高云母含量石粉混凝土性能试验研究
Study on performances of concrete with high. content of mica in stone powder
摘要
Abstract
The mica content of stone powder in manufactured sand is higher when the sand is made by crushing rocks of higher mica content. The effect of mica content in stone powder on the performances of manufactured sand concrete is experimentally studied in this work, with the mica content controlled by adjusting stone powder content of manufactured sand from 6% to 18%. Experimental results show that the stone powder with high content of mica has adverse effects upon concrete performances, such as water content, workability and tensile strength etc. With higher content of mica in stone powder, the concrete will have higher water content, worse workability and lower tensile strength. And the ratio of tensile strength to compressive strength is lower.关键词
