![]() Used to build highways, airports, and embankments. Rapid hardening concrete - mostly used in underwater construction and road repairing.Īsphalt - the combination of aggregates and asphalt. Glass concrete - recycled glass is used as an aggregate. Prestressed Concrete - a special type of reinforced concrete in which the reinforcement bars are tensioned before being embedded in the concrete.Īir-entrained concrete - specially prepared plain concrete in which air is entrained in the form of thousands uniformly distributed particles. Precast concrete - the term refers to prefabricated concrete blocks. In this concrete type, steel in various forms is used as reinforcement to give a very high tensile strength. Reinforced concrete - most important type. It is mostly used in atomic power plants (good radiation protection). The density varies between 3000-4000 kg/m³. High-density concrete - also called heavy weight. Lightweight concrete - density lower than 1920 kg/m³. Made of cement, sand and coarse aggregates. ![]() Ordinary or plain concrete - one of the most commonly used. Assuming 5% is lost to waste and spillage - voila! We need 284 bags of concrete.Ĭoncrete is produced in a variety of compositions, finishes and performance characteristics to meet a wide range of needs. The total weight of concrete that we need is 16,201.03 lb. We need 4 cubic yards of concrete our producer sells concrete in bags weighing 60 lb with a 150 lb/cu ft density. In our example, let's leave the default measures. Experienced contractors usually assume 5-10%. To be safe, account for spillage and waste.If not, again, change it to the appropriate number. Check if the weight of a single bag of concrete is the same as the default already given (60 lb).Now, the total weight of concrete you need is shown. ![]()
