The most important mechanical properties of hardened concrete

The most important mechanical properties of hardened concrete, concrete means to resist the pressure, pulling, bending, shear, such as the ability to stress. Water-cement ratio, cement variety and amount of variety and amount of aggregates and mixing, forming, curing, have a direct impact on the strength of concrete.Concrete Mixing and Batching Plant Standard compressive strength of concrete (with a side length of 150mm cube as the standard specimen, curing 28 days under standard curing conditions, as measured according to the standard test method has a 95% guaranteed rate of cube compressive) strength class division called numeral, divided C10, C15, C20, C25 and the like. Tensile strength of concrete compressive strength is only 1/13 to 1/8. Improve concrete tensile, compressive strength ratio is an important aspect of concrete modified.
