摘　　要：理论研究表明,采用煤矸石部分取代天然骨料配制强度等级C35以下的低强度混凝土是可行的。但在实际工程应用时还存在因煤矸石自身强度低、内部构造特殊、针片状颗粒含量大等现象,导致现行标准规程不适用、影响泵送等问题。建议国家有关部门抓紧制定专门用于煤矸石骨料的技术标准,以利于煤矸石骨料的推广应用。The theoretical research shows that it is feasible to partially replace low strength concrete with natural aggregate strength grade below C35 with coal gangue.However,there are still some problems in practical engineering application,such as low strength of coal gangue,special internal structure and large content of needle flake particles,etc.,which may cause the current standard specification failure,and affect the pumping.So it is suggested that the relevant departments should formulate corresponding technical standards in order to promote the application of coal gangue aggregate.

关 键 词：煤矸石骨料 配合比设计 煤矸石混凝土 可泵性
