Coal gangue Portland cement clinker and preparation method thereof
The invention belongs to the technical field of constructional engineering, relates to a cement clinker, and particularly relates to a coal gangue Portland cement clinker and a preparation method thereof. The technical key points are as follows: the concrete clinker is prepared from the following components in parts by weight: 200-250 parts of limestone, 130-140 parts of a coal gangue admixture, 80-90 parts of iron ore powder, 10-15 parts of aggregate, 30-40 parts of an excitant and 5-10 parts of aluminum ash. According to the coal gangue Portland cement clinker and the preparation method thereof, the prepared coal gangue Portland cement clinker can effectively improve the early strength of cement, reduce the water demand of the cement, reduce early shrinkage of the cement in the cement curing process and delay release of heat of the cement, so that late shrinkage of cement curing is reduced, the 3d strength and 28d strength of the cement are improved, and meanwhile, the alkali-aggregate reaction is avoided.
本发明属于建筑工程技术领域，涉及一种水泥熟料，更具体的涉及一种煤矸石硅酸盐水泥熟料及其制备方法。其技术要点如下：按照重量份数计算，包括如下组分：石灰石200~250份，煤矸石掺合料130~140份，铁矿石粉80~90份，骨料10~15份，激发剂30~40份和铝灰5~10份。本发明提供的一种煤矸石硅酸盐水泥熟料及其制备方法，制备出的煤矸石硅酸盐水泥熟料能够有效提高水泥的早期强度、降低水泥需水量，且在水泥固化过程中减少水泥的早期收缩，延缓水泥的热量的释放，从而减少水泥固化的晚期收缩，提高水泥的3d强度和28d强度，同时避免碱骨料反应的发生。
