WebThe Rheology of concrete may be defined as the science of the deformation and flow of materials. The term rheology deals with the materials whose flow properties are more complicated than those of simple fluids. It is concerning relationships between stress, the rate of strain, and time. The rheological principle and techniques are applied to ... 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.
