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. However, if no provision is made for expansion, very large forces can be … See more Portland cement concrete holds water. However, some types of concrete (like Pervious concrete) allow water to pass, hereby being perfect alternatives to Macadam roads, … 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 … 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 … See more Creep is the permanent movement or deformation of a material in order to relieve stresses within the material. Concrete that is subjected to long-duration forces is prone to … See more WebIn the flow table test workability of concrete is determined by observing the flowing property of concrete. It is a lab test that suits low concrete workability. This test was also used to determine consistency, cohesiveness, and the proneness to segregation. Workability is a very complex characteristic of concrete that directly impacts ... increase font size in gedit
