Abstract
High efficiency water reducing agents are mainly used to improve the performance of concrete,with a general dosage not exceeding 5%of the cement dosage.This article focuses on studying their impact on the shrinkage performance of high-performance concrete,selecting reasonable experimental raw materials,instruments and equipment,and mix proportions.Based on two forms of water reducing agent addition,experiments are conducted.The results show that the use of water reducing agents will increase the shrinkage deformation of high-performance concrete,and timely control measures need to be taken to improve the volume stability of concrete.关键词
