摘要
针对较多无砂大孔混凝土配制透水混凝土的技术,在掺入细集料的情况下,研究不同砂率、不同粒径及连续大粒径对透水速率和混凝土强度的影响,并给予相应的改善措施,为今后工程中配制透水混凝土提供参考。
Employing the sand free larger hole technology for the preparation of porous concrete under the condition of mixing with fine aggregate, the experiment focuses on the influence of different sand ratio, different sizes and continuous particle size distribution on permeable rate and concrete compression strength. It provides the corresponding improvement measures with references for preparation of permeable concrete in future projects.
