[摘要] 針對(duì)煤矸石占用大量耕地并對(duì)環(huán)境造成污染等問(wèn)題，對(duì)阜新高德礦堆積的自燃煤矸石進(jìn)行了性能測(cè)試，通過(guò)機(jī)械破碎、篩分級(jí)配等制成煤矸石粗細(xì)集料代替天然砂石配制C15~ C40共6組煤矸石全集料混凝土試件，進(jìn)行了抗壓、劈拉試驗(yàn)。研究結(jié)果表明：煤矸石集料可以代替天然集料制備出C15~ C40不同強(qiáng)度等級(jí)的混凝土，其配制的混凝土性能優(yōu)良，不僅實(shí)現(xiàn)了固體廢棄物的減排目標(biāo)，而且緩解了硬質(zhì)石材短缺的問(wèn)題，具有雙重效益。

Abstract: The properties of spontaneous combustion gangue produced from Fuxin Gaode nune were tested, aiming at solving the problems of gangue, such as taking up a lot of farmland and polluting the environment etc. Then mechanical crushing and screerung grading methods were used to make gangue aggregate in place of natural sand.  Six groups of C15-C40 concrete specimens were made and the compressive strength and splitting strength test was carried out. The results show that gangue aggregate can take the place of natural sand to make different strengths of nice-feature concrete. At last, the methods could not only aclueve the solid waste reduction but also alleviate the problem of shortage of hard stone materials, which getting the double benefits.
Keywords: spontaneous combustion gangue; aggregate; concrete; strength
