摘要
通过试验 ,研究了高掺量粉煤灰碾压混凝土的孔结构特征、随龄期延长孔隙构造的发展变化以及高压水渗透对孔结构的作用 ;论述了碾压混凝土配合比和龄期对原生孔结构及孔结构发展变化的影响 ;
Through the experiments, pore structure characteristic, the expanding and changing of pore structure with age period and the effect of high pressure water to pore structure of RCC(Roller Compacted Concrete) made with high volume fly ash were researched. The factors of RCC mix proportion and age affecting pore structure were disscussed, the permissible fly ash content of RCC used on has been exploned.
