Chat OnlineLean concrete is made with low cementitious material content.This means that it does not have many of the heavy, high-density rock and sand elements that normal concrete has.Instead, it can use a mixture of standard concrete materials, reclaimed and crushed concrete, discarded sand and recycled ash.
Chat OnlineConcrete is a mixture of cement, fine and coarse aggregates, water, and sometimes some supplementary materials like fly ash, slag, and various admixtures.A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard).The unit weight of concrete (density) varies depending on the amount and density.
Chat Onlinequestion: what's the nominal weight of standard concrete? answer: anyone who has ever moved it by the shovelful will tell you fresh concrete is heavy, but just how heavy it is depends on the mix proportions and the particular ingredients.A good rule of thumb for most concrete mixtures is 150 pounds per cubic foot.If you fill a 5-gallon bucket you've moved nearly 100 pounds of concrete.
