Experimental Study on the Influence of Fly Ash on Mechanical Properties and Shrinkage Performance of Concrete

摘要

Fly ash is a commonly used concrete admixture, which can improve its durability. In this paper, a series of experiments were made to study the influence of the amount of fly ash additive on the mechanical properties and shrinkage properties of concrete, which provides reference for the preparation of fly ash concrete. The results proved that the mixing of fly ash can improve the strength of concrete, restrain the production of concrete shrinkage cracks, and the fly ash plays a role in the late stage of concrete strength growth.
