WebFor normal concrete, the weight of a cube of one cubic metre is between 2,000 and 2,600 kg. Heavy concrete. Concrete with an apparent density of more than 2,600 kg/m3 is called heavy concrete. As radiation protection concretes, heavy concretes shield dangerous radiation, for example in the radiology department of a hospital. WebNormal Weight of Concrete: A normal concrete can weigh between 140 to 150 Lbs/ft³ due to the presence of heavier aggregates in the natural state. Weight of Lightweight Aggregate Concrete: The weight of Lightweight Aggregate Concrete is 115 pounds per cubic foot, and the average concrete weight is 145 pounds per cubic foot.
