摘要
机制砂中含有石粉是机制砂与天然砂之间最显著的区别之一,而石粉对机制砂混凝土性能影响也是机制砂混凝土研究的重点。文章详细的介绍了石粉对机制砂混凝土工作性、力学性能、体积稳定性以及耐久性能影响的国内外研究现状。并探讨了石粉对机制砂混凝土性能影响研究中存在的问题。
One of the most remarkable difference between manufactured sand and natural sand is stone dust whose particle size is less than 0.075mm,and influence of stone dust on manufactured sand concrete is the current research focus.In the paper,the researching development of influence of stone dust on the workability,mechanical property,volume stability and durability of manufactured sand concrete is summarized at home and abroad.And existing problems of the researching results is discussed and analyzed.
