One cubic yard of concrete weighs around 4,000 pounds. Concrete is measured in cubic yards. Concrete is made out of sand, gravel and cement. Cement is made out of limestone, silica and alumina. Cement is a gray powder that reacts with water to harden the concrete.
Concrete 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).he rule of thumb is to consider that a 94 lb. bag of cement will make one cubic foot when it is freshly packed. The density of lightweight concrete is 1920 kg per cubic meter or 116 lbs per cubic foot (3132 lbs per cubic yard).
