The most important properties of concrete mixtures. It comprehensively expresses the consistency, the fluidity, the plasticity, the anti-demixing and segregation bleeding performance, the easy-to-smear property and the like of the mixture. Methods and indexes for measuring and expressing the workability of the mixture are many, and China mainly measures the mixture workability by using a truncated cone slump cone. The most important mechanical property of the hardened concrete refers to the capability of the concrete to resist stress such as compression, tension, bending, shearing and the like. The water cement ratio, the variety and the dosage of cement, the variety and the dosage of aggregate, stirring, forming and curing all directly influence the strength of concrete. The concrete is classified into strength grades according to standard compressive strength (cubic compressive strength with 95% guarantee rate measured by standard test method by using a cube with side length of 150mm as a standard test piece and curing for 28 days under standard curing conditions), which are called as labels and are classified into C10, C15, C20, C25 and the like. The tensile strength of the concrete is only 1/13-1/8 of the compressive strength of the concrete. The improvement of the ratio of tensile strength to compressive strength of concrete is an important aspect of concrete modification.
