Concrete prepared from industrial production waste and preparation method thereof
The invention relates to concrete prepared by taking industrial production wastes as main raw materials. Specifically, the invention provides concrete containing mineral powder and coal gangue aggregate as main raw materials, the coal gangue aggregate is coal gangue fine aggregate or coal gangue mixed fine aggregate and coal gangue coarse aggregate or coal gangue mixed coarse aggregate, and a) the mass ratio of the coal gangue fine aggregate to the coal gangue mixed fine aggregate is not higher than 50%; b) the mass ratio of the coal gangue coarse aggregate to the coal gangue mixed coarse aggregate is not higher than 40%; or c) a combination of a) and b). The invention also provides a preparation method of the concrete.
本发明涉及一种由工业生产废弃物为主要原料制备的混凝土。具体地，本发明提供了一种包含矿粉和煤矸石骨料为主要原料的混凝土，所述煤矸石骨料为煤矸石细骨料或煤矸石混合细骨料，和煤矸石粗骨料或煤矸石混合粗骨料，其中a)煤矸石细骨料与煤矸石混合细骨料的质量比不高于50％；b)煤矸石粗骨料与煤矸石混合粗骨料的质量比不高于40％；或c)a)与b)组合。本发明还提供了上述混凝土的制备方法。
