Effect of Mineral Admixture on the Mechanical Properties of the RAC Activity
摘要
Abstract
In order to study the mineral admixture on the properties of the RAC interface improvements, the 174 groups of 522 active mineral enhanced RAC mechanics performance test, analyzed the mineral admixture under different content and volume rate on mechanical properties of RAC and changed rule of the influence of the deformation performance.Research results show that the fly ash (FA) on the early compressive strength of RAC cube is larger, with the increase of the content of the cube, the cube compressive strength show different degrees of reduction.With the increase of water reducing agent (PS) and silica fume (SF), the decline increases.But the axial compressive strength, splitting tensile strength and flexural strength, enhancement effect is more obvious.Along with the change of FA,PS and SF levels, the peak strain decreases.However, the elastic modulus increases with the increase of FA and PS.关键词
