摘　　要：提出了微细颗粒增强多孔混凝土研究方法,该方法仍以含砂多孔混凝土中细集料作用机理为基础,但作用形式完全改变,该方法在提高多孔混凝土强度的基础上,可以有效保证多孔混凝土的连通孔隙,且试验中微细火山渣、微细矿渣、微细石英砂试验组最优试验组,比标准试验组分别提高了30.1%、37.7%、50.8%。It presents the research method of micro particle reinforced porous concrete.The method is still based on the action mechanism of fine aggregate in sand containing porous concrete,but the form of action is completely changed.This method can not only improve the strength of porous concrete,but also effectively ensure the connectivity of porous concrete.In the experiment,the best experimental group of micro slag,fine slag and fine quartz sand was increased by 30.1%,37.7%and 50.8%respectively compared with the standard experimental group.
