Mortar for improving overall performance based on fine coal gasification slag and preparation method thereof
The invention belongs to the technical field of building materials, and discloses mortar for improving overall performance based on fine coal gasification slag and a preparation method of the mortar. The mortar is prepared from the following components in percentage by mass: 11 to 20 weight percent of cement, 58 to 75.8 weight percent of standard sand and 2.2 to 11.1 weight percent of coal gasification fine slag; screening the fine coal gasification slag, diluting the fine coal gasification slag with other raw materials by adding water, and stirring to prepare fine coal gasification slag slurry; fully stirring the coal gasification fine slag slurry, introducing the coal gasification fine slag slurry into a screening device, screening the coal gasification fine slag slurry through a 200-400-mesh sieve to separate out large-particle solid components, and collecting undersize separation slurry to obtain composite slurry; according to the method, the mixing amount of the coal gasification fine slag for replacing part of cement and the parameters of the method are accurately controlled, the content of hydration products in the neat paste is effectively increased finally, and meanwhile, the content of CSH gel in the system is increased.
本发明属于建筑材料技术领域，公开了一种基于煤气化细渣提高整体性能的砂浆及其制备方法；所述砂浆包括质量分数为11~20wt%的水泥、58~75.8wt%的标准砂和2.2~11.1wt%煤气化细渣；将煤气化细渣筛分处理，然后和其他原料加水稀释搅拌制成煤气化细渣浆料；再将煤气化细渣浆料充分搅拌后导入筛分装置，过200~400目筛分离出大颗粒固体组分，收集筛下分离浆料得到复合浆料；本发明对煤气化细渣取代部分水泥的掺量以及方法参数进行了精准的控制，并最终有效提高了净浆中水化产物的含量，同时增加了体系中CSH凝胶的含量。
