Design method for mix proportion of high-performance coal gangue fine aggregate concrete
The invention discloses a design method of a mix proportion of high-performance coal gangue fine aggregate concrete, and relates to the technical field of preparation of concrete materials from solid wastes. Wherein the solid waste is natural coal gangue fine aggregate which is obtained after spontaneous combustion coal gangue is crushed and has the grain composition similar to that of natural river sand, the coal gangue fine aggregate belongs to lightweight aggregate and replaces the natural river sand to serve as fine aggregate according to the volume ratio, and fly ash is added to improve the working performance of the concrete; the problem that common coal gangue concrete is poor in working performance is solved. The coal gangue fine aggregate concrete with high strength and good performance is prepared by crushing the coal gangue as the fine aggregate, mining of natural sand is saved, a large amount of coal gangue is consumed, and the method is an effective practical method for solving environmental problems through solid waste utilization.
本发明公开了一种高性能煤矸石细集料混凝土配合比的设计方法，涉及固体废弃物制备混凝土材料技术领域。其中，固体废弃物为将自燃煤矸石破碎后得到颗粒级配与天然河沙相近的自然煤矸石细集料，煤矸石细集料属于轻骨料通过体积比替换天然河沙作为细骨料，并加入粉煤灰提高混凝土的工作性能，解决了普通煤矸石混凝土工作性能差的问题。本发明将煤矸石破碎作为细骨料制备一种强度高、性能好的煤矸石细集料混凝土，节约了天然砂的开采，又消耗了大量的煤矸石，是有效的固废利用解决环境问题的实际方法。
