RESEARCH ON THE APPLICATION OF ADDITIVE TARGETED CONTROL METHOD TO CONCRETE PERFORMANCE
To help concrete enterprises cope with the rapid change of production materials,strength grades,and dif-ferent construction performance requirements of concrete,this paper studies the influence of different proportions of slump retention and water reduction components on the fluidity of the net slurry,the expansion degree of three types of machine-made mortar,the slump degree of concrete,and its loss over time.The results show that appropriate ratio of slump retention admixture and water reduction admixture can be quickly determined with the expansion degree of mortar and applied to the regulation of the proportion of admixtures in concrete,providing the reference significance for concrete production enterprises to ensure the stability of concrete mixture.
