Influence of charging mixing order on concrete performance
Abstract
To know whether or not the concrete performance will be effected by the charging mixing order of three materials including the fine materials, the hydrophobic materials and the poriferous internal curing materials, three kinds of charging mixing order were designed. The slump of fresh mix concrete was tested. The compressive strength of harden concrete was tested. The pore structure was also detected. The test results show that charging mixing order can effect on the slump of concrete. While, it has no effect on compressive strength and pore size distribution. About the pore parameters, charging mixing order can effect on the average pore diameter and the critical pore diameter. It has no effect on the porosity of the concrete.
