Abstract

Abstract

Four groups of high performance concretes were designed, in which the content of pumice and zeolite wasdifferent, and twelve specimens were produced for each group. Three specimens had been eroded in lime saturatedwater, three in MgSO 4 solution, and three in NaCl solution for two years. Then the freezing and thawing experimenton them was done. In the experiment, the change of weight and compressive strength of high performance concretewhich had been eroded in different salification solutions was studied, meanwhile, the effects of different mineraladmixture on salification erosion resistance durability of high performance concrete were analyzed. The tests resultsshow that MgSO4solution' s erosion of high performance concrete is severer than NaCl solution, besides, salificationerosion resistance durability of high performance concrete with pumice and zeolite is good, and it increase with theincrease of zeolite content in high performance concrete.
