WebDensity of Concrete Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is … The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1] Reinforced concrete is the most common form of concrete. The reinforcement is often steel rebar (mesh, spiral, bars and other forms). Structural fibers of various materials are available. See more 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 … See more Concrete has relatively high compressive strength, but significantly lower tensile strength. As a result, without compensating, concrete would almost always fail from tensile stresses (Stress (mechanics)#Mohr's circle) even when loaded in … See more The modulus of elasticity of concrete is a function of the modulus of elasticity of the aggregates and the cement matrix and their relative … See more As concrete matures it continues to shrink, due to the ongoing reaction taking place in the material, although the rate of shrinkage falls relatively quickly and keeps reducing over time … See more The ultimate strength of concrete is influenced by the water-cementitious ratio (w/cm), the design constituents, and the mixing, placement and curing methods employed. All things being equal, concrete with a lower water-cement (cementitious) ratio makes a … See more Expansion and shrinkage Concrete has a very low coefficient of thermal expansion. However, if no provision is made for expansion, very large forces can be created, causing cracks in parts of the structure not capable of withstanding the … See more Creep is the permanent movement or deformation of a material in order to relieve stresses within the material.

WebIn this study, Equation (7), presented by Salman [56] was used to determine the air-dry density of concrete. (7) γ = 114.8 · V L + 1813. where: γ—air-dry density (kg/m 3) and V L —ultrasonic pulse velocity (km/s). In order to establish the accuracy of the proposed equation, the air-dry density of concrete was experimentally determined.
