Because a cubic foot of fresh water only weighs 62.4 pounds and exerts less upward force, its apparent weight would be 87.6 pounds. A 6-inch thick slab weighs 72.5 pounds per square foot, the maximum allowable weight. Among the most spectacular examples is Romes Pantheon, a well-preserved cylindrical temple. The density of concrete varies based on its composition, but average density of concrete is around 2,400 kilograms per cubic meter (150 pounds per cubic foot). per cubic foot. The average weight per cubic yard of a solid slab of concrete is 4,050 pounds (2 tonnes), or 150 pounds per cubic foot. In three years, Chinese engineers used more concrete than the U.S. did through the entire 20th Century. Ready-mix concrete also removes irregularities in the concrete caused by human error. The buildings dome was an impressive technical achievement for Roman architects and engineers. To build one yard of concrete, youll need roughly 20-25 gallons of water, which weighs about 8 pounds each gallon. Wall Height (feet) width x12. A good rule of thumb is take your calculation and add 4% to 10% to the total to account for waste, spillage, over-excavation, settlement, spreading of forms, loss of entrained air or any other changes in volume. In 1902, French architect Auguste Perret applied a similar approach. Unit volume. Total concrete you will need is: Volume in Cubic Feet = Volume in Cubic Feet Under Platform + Volume in Cubic Feet Under Stairs Conversion in other common units: Volume in Cubic Yards (yd3) = Volume in Cubic Feet (ft3) / 27 Volume in Cubic Meters (m3) = Volume in Cubic Feet (ft3) x 0.0283 Understanding the Concrete Calculator This reduces waste and improves the integrity of the concrete. Quantity * Note that our Concrete Calculator uses the stats of premixed cement density, which is 2,130 kg/cubic meters, and 133 pounds/cubic feet in order to calculate the weight of concrete which is required. When buildings sway, the easier-to-fix mortar is the first to break. It has been around for millennia, far longer than there has been concrete. Type the zip code of the delivery address to see available products and prices. Since 1 cubic foot of concrete weighs 150 lbs, you divide that by 1728 to get the weight of concrete per cubic inch. This concrete calculator determines the volume and weight of the concrete required to build a specific land with premixed cement. Adding just 1 gallon of water per cubic yard can decrease . density of concrete, Asphalt is equal to 2 243 kg/m. That means a concrete of 6 foot width, 6 foot height, and 6 foot length will have a weight of 900 pounds (if it is a solid slab). This reduces the ambient temperatures as they absorb less heat. They add concrete to a pre-built framework of steel reinforcement bars (rebar). Estimate the density of the hotmix to be used. Changing the proportions of ingredients will yield a concrete with different properties. When mixing it, the concrete becomes a paste than can further on fill spaces among the aggregate particles of the construction. The individual weights of aggregate, cement, sand, and water in a yard of concrete are: 517 pounds of cement (234 kg) With this formula in mind, you'll be able to calculate just how much concrete or cement you'll need for your project: One 60-lb bag of concrete gives you .45 cubic feet of concrete when mixed with 2.5 quarts of water. They didnt see concrete as a building material for houses and public buildings at first. The calculator will automatically estimate the number of cubic yards of concrete that will be required. Some cement additives help improve the durability of concrete in extreme conditions. Compressive Strength. They even created special maritime concrete to use in ports and coastal constructions. High concentrations of sulfates can cause rapid erosion of concrete in two ways. It is a mass to volume ratio that determines density. A real estate juggernaut, China alone accounts for much of this consumption. This mix is difficult to use. Theres only so many ways to stop rebar rusting from within concrete. Once the process completes, the concrete sets. Unlike the Romans, the 19th Century Europeans thought lowly of concrete. Engineers have optimized each type to perform best in the prevailing climate environment. In a process called sintering, the mixture fuses together. These are custom ratios formulated for the specific needs of the construction project. To put it another way, a block of concrete that is one foot wide, one foot long, and one foot high would typically weigh 150 pounds when measured in pounds per cubic foot (lb/ft3). That was more air pollution than both China and the United States combined! The building still stands today in Port Chester, New York. Concrete is remarkably durable. In every town and city today, youre bound to see at least one thing made of the substance. The weight per square foot is 47.85 pounds when divided by the number of decimal places in the formula (4/12). This simple house is the first residence made of true reinforced concrete. (this gives you the depth in feet.) Many surviving Roman concrete structures still remain in good condition today. They lived in an arid, drought-prone region. One hundred forty-five pounds per cubic foot x.5 = 72.5 pounds per cubic foot or 72.5 pounds per cubic meter. An alternative method of calculation is square footage divided by depth. Vaclav Smil, author of Making the Modern World, notes that the Chinese demand for concrete far outpaces even that of the United States. Concrete and steel architecture continued to soar throughout the 20th and 21st centuries. The water ratio of concrete determines its workability. The resulting material, clinker, must then be ground up. Here's what the math looks like for a 10' by 10' concrete patio: 10 x 10 = 100 square feet. Material Volume Weight (pounds) Weight (tons) Cubic Yards Per Ton Trash 1 cubic yard 350 .175 5.71 Cans & Bottles 1 cubic yard 50 .025 40 Cardboard 1 cubic yard 100 .05 20 Drywall 1 cubic yard 500 .25 4 Scrap Metal 1 cubic yard 1,000 .5 2 Scrap Wood 1 cubic yard 300 .15 6.66 28 This is a popular option for large-scale construction projects. Do you know the weight of a 4-inch-thick slab of concrete? Other times, engineers must keep setting concrete wet through a process called curing. Use 150 and the steel is included unless heavily reinforced as Lomarandil noted. This was soon followed in 1903 by the high-rise Ingalls Building in Cincinnati, Ohio. How many cubic yard of concrete in pounds of cement? The first major innovation was the rotary kiln. Multiply the length by the width to calculate the square footage of concrete. After the mixing process, start using the concrete to fill in spaces you planned to, because it quickly hardens. Calculates for shapes like: slabs, walls, square footings. They have a greater volume of water in the mixture by design. Incorrect formulations can create voids in the concrete, which will lead to cracking. Thus, their quality is predictable. Keep in mind that concrete is typically poured to be 3-4 inches thick. This saves builders a lot of time and money. To increase the usefulness, the tool also returns the number of concrete bags within few categories (60lbs, 80lbs or 100 lbs bags). Concrete behaves like a porous liquid when first mixed. Use too much water, however, and you compromise the strength of the resulting concrete. If you need to convert to cubic feet from yards: multiply your final number by 27. Weight of the concrete per volume of concrete. Reference Workers have a limited time to mold and shape the concrete before it sets. The total concrete needed for the 3' by 3' porch will be .28 cubic yards. Concrete is ordered by volume in cubic yards. This equals .039 kg. He designed a reinforced concrete apartment building in Paris whose facade impressed onlookers. When stretched, the tendrils within the concrete fall apart. It is a strong conglomerate construction material and is obtained by mixing specific quantities of cement with specific quantities of granular material such as sand, fibers. The mix design process can either be conducted on the basis of charts or experimentally. This totals .17 cubic yards. The first true concrete was made from lime extracted from limestone. To neutralize these chemicals, the cement used must have a low alkalinity. Multiply the volume by the density (in the same units) to get the weight A cubic foot of concrete weighs 137 pounds. The damage that results is expensive to repair and replace. Concrete is ordered by volume in cubic yards. According to the materials and ratios employed, as well as the amount of water used in mixing, the actual weight per yard can vary greatly. Finally, concrete is a great way to recycle various infill materials. Note: While different mixes have different density levels, these calculators presume a density of 133 pounds per cubic foot or 2,130kg/cubic meter. Standard density for asphalt is 145 lb/ft 3 (2322 kg/m 3 ). For comparison a square foot of 1.5 inch thick granite is 17.5 pounds. Calculate Crusher Run. 6, 7), for further information. Tables 1 through 8 list concrete masonry wall weights for 4 to 16 inch (102 to 406 mm) thick single wythe walls. Specialty cements may include pozzolana ash to increase its durability further. 1 cubic yard = 27 cubic feet. They are 4 feet in height and 10 inches in width (diameter), or 4 x 10. You must use the appropriate amount of water to catalyze the reaction. Although different from todays Portland cement, the resulting mix was quite strong. It is also used in masonry constructions and as a binder for stucco wall finishes. As it does, it creates voids within the concrete that causes it to lose some of its strength and integrity. Even though concrete countertops weigh less than regular concrete, its still simpler to polish standard density concrete because of the 3.5 pounds per square foot weight savings.

Headquarters: 3823 Raleigh St. Charlotte, NC 28206, Shelco, LLC and I have enjoyed a business relationship with Concrete Supply for nearly 30 years. His work on the composition of lime paved the way for more refined concrete recipes. His kiln had a length of 150 feet (45.72 meters), allowing him to scale up production by a large margin. The calculation process is: Estimate the volume of asphalt needed, using geometrical formulas and plans or measurements, including width, length, and depth (thickness). Cement is heavier than sand in terms of scientific weight! Calculate the volume of cubic yards needed to create a tube or circular slab. The other substance of choice for cement is hydraulic lime. El-Dieb, A. S. (2007). Water is another important element to consider in formulating concrete. The skilled engineers of the Roman Empire developed concrete formulas for various applications. Acid rain, with high levels of sulfuric acid, can cause slow but devastating damage to concrete structures. If you divide 3700 pounds by 27 you get 137 pounds per cubic foot. Sometimes, builders must avoid putting too much water onto the concrete. Calculate the volume of cubic yards needed to fill in a hole, column or round footing. Please note that this is only an estimation based on your input, therefore the decision to buy specific concrete quantity is entirely yours. Engineers must be careful to keep these air pockets small. The water-to-cement ratio is a good way of determining the right amount of water for your needs. These were precursors to reinforced concrete. Thus, it must arrive on time to remain usable. One way of measuring water content in mixed concrete is through the slump test. The resulting material was ground up for use. 6/12 = 5. Main Office 11143 Goodnight Lane Dallas, TX 75229. Theres little wonder why we call the modern city the concrete jungle.. This indicates a ratio of one one part cement, one part water, and two parts coarse aggregates. A pre-made batch of concrete guarantees consistency. Early modern forms of concrete use natural cement mixes. It also protected them from outside erosion. And these were built to last. 4050 lbs divided by 27 cubic feet = 150 lbs. The aggregate materials often stay separated. This is a house tool that can help you estimate the cement requirements for your construction project. This is the standard mixture ideal for most uses of concrete. The production of clinker produces a lot of pollution in the form of carbon dioxide (CO2). Weight. They need only to be heated to be usable. Length (feet) length x12 Width (inches) width x12 Depth (inches) While additives can slow down the reaction, these are often not enough.

This was invented by English engineer Frederick Ransome in 1873. These may interfere with the creation of concrete. A cubic yard of cured concrete, or 4050 pounds per cubic yard, based on Imperial as well as US customary measurement systems, is roughly equivalent to 2400 kilogrammes (2.4MT) per cubic meter (m3) in the metric system, or 150 pounds per cubic foot in the Imperial system. Not only is concrete strong, it is also very cheap. These are designated by the American Society for Testing and Materials (ASTM). It is not evaporation that makes concrete hard. The effects of sulfate attacks depend on the type and concentration of sulfates in the area. Scientists from the University of California at Berkeley analyzed Roman concrete samples. Effect of high temperature or fire on heavy weight concrete properties. Calculate the volume of cubic yards needed to fill in a hole, column or round footing. With the above mentioned two-units calculating service it provides, this concrete converter proved to be useful also as an online tool for: 1. practicing cubic feet and pounds of concrete ( cu ft - ft3 vs. lb ) measuring values exchange. Modulus of Elasticity. For most modern building applications, plain concrete is not up to the task. So, the 6-inch slab is 5 feet thick. (102-mm) concrete masonry walls are . Share calculator: Thus, strict planning is essential for the effective use of ready-mix concrete. Concrete is ordered by volume in cubic yards. Aspdin relied on vitrification to fuse the materials together in the finished cement. It uses a premixed cement density of 133 pounds per cubic foot (60 pounds/0.45 cubic feet, or 80 pounds/0.60 cubic feet) or 2,130kg/cubic meters to obtain the weight in the result. Concrete Supply Co., LLC is committed to protecting the Environment through sensible and responsible operating activities. Self-curing concrete: Water retention, hydration and moisture transport. In most cases, a decrease in concrete density results in a reduction of concrete strength. As an example, 1 cubic foot of concrete at 145 pcf + 1% min reinforcing yields a unit weight of about 150 pcf. Concrete Footing Calculator To use the Concrete Volume Calculator, simply enter the width, length, and thickness of your pour. Builders can create all kinds of intricate shapes using molded concrete. One hundred forty-five pounds per cubic foot x.5 = 72.5 pounds per cubic foot or 72.5 pounds per cubic meter. How Much Does a Cubic Yard Weigh? The ingredients for modern concrete are quite easy to find. Concrete: Laying the Groundwork for the Modern World Lime mortars brittleness can be used to prevent damage in these older buildings. It weighs less because it is created of pumice, an inherently light mineral. 1. Using volume, you can easily calculate the weight of concrete. We look forward to serving you. In comparison, the density of sand ranges from 2.65 to 2.67. The two create a gelatinous mass that suspends any material mixed into them.
