Design of concrete mix ratio and the influence of high water absorption resin and water reducer on strength and working performance

Abstract

The performance of concrete and water cement ratio, water ratio and unit water consumption has a close relationship, concrete mix ratio design is actually to determine the proportion between the three, correctly determine the proportion relationship, can make concrete meet the design requirements. This paper systematically studies the working performance of concrete with different strength grades, and then compares the experimental results with the four concrete strength grades designed. High water absorption resin process increases the tightness of the slurry, to improve the working characteristics of cement, and then improve the durability of cement function. The influence of the high absorption resin curing agent and water reducing agent on different concrete strength and working performance is studied. The test data between high water absorption resin and absorbent are used to form the change curve of various strength grades, the interaction mechanism between high water absorbent resin and absorbent is analyzed, and puts forward an important scientific basis for the study of cement mix ratio.
