WebConcrete 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. For the production of heavy concrete, special aggregates with a high bulk density are used, e.g. baryte or ilmenite. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). Reinforced concrete is the most common form of concrete. The reinforcement is often steel rebar (mesh, spiral, bars and other forms). ... For normal weight concrete ... Ver mais Concrete has relatively high compressive strength (resists breaking, when squeezed), but significantly lower tensile strength (vulnerable to breaking, when pulled apart). The compressive strength is typically controlled … Ver mais Concrete has relatively high compressive strength, but significantly lower tensile strength. As a result, without compensating, … Ver mais The modulus of elasticity of concrete is a function of the modulus of elasticity of the aggregates and the cement matrix and their relative proportions.
