Flowing property of concrete
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 with the ratio of water to cement when forming the concrete, and tensile strength is increased by … 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 ( Reinforced concrete is … 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 Expansion and shrinkage Concrete has a very low coefficient of thermal expansion.
