The invention relates to a building auxiliary material, in particular to a rapid setting filler for cement concrete. The rapid setting filler comprises the following raw materials: coal cinder, sodium carbonate, calcium chloride, sodium silicate, sodium metaaluminate, ferric chloride, asphalt emulsion, gypsum, a filler and a modifier. The coal cinder is taken as a main material, so that the compression resistance, fracture resistance and frost resistance of the concrete can be improved; in addition, the coal cinder is a sintered pozzolanic material, has hydraulic gelling performance after being ground, and can be matched with cement clinker and cement in the concrete or lime and gypsum for use; polyvinyl chloride can be used for producing lightweight concrete, and the produced lightweight concrete is light in weight, high in heat insulation and sound insulation; anhydrous glycerin is a good cement hydration inhibitor; tetraethoxysilane is hydrolyzed to consume water, and forms a volatile azeotropic hydrate with isopropanol and water, so that volatilization of water in the concrete is accelerated; and the tetraethoxysilane is hydrolyzed to form silicon dioxide, so that the bonding performance of the concrete is improved.
本发明涉及一种建筑辅助材料，具体是一种水泥混凝土的快速凝固填充剂,水泥混凝土的快速凝固填充剂原料包括煤渣、碳酸钠、氯化钙、硅酸钠、偏铝酸钠、氯化铁、沥青乳液、石膏、填充剂、修正剂。以煤渣作为主材料可以提高混凝土的抗压、抗折、抗冻性能，另外，煤渣为烧结火山灰质材料，磨细后具有水硬胶凝性能，可同混凝土中的水泥熟料、水泥或同石灰和石膏相互配合使用；聚氯乙烯可生产轻质混凝土，所产的轻质混凝土质量较轻，高度隔热，并且隔音；无水甘油为良好的水泥水化抑制剂；四乙氧基硅烷水解消耗水分，并和异丙醇及水形成易挥发的共沸水合物，加快混凝土中水分的挥发；四乙氧基硅烷水解形成二氧化硅，改善混凝土粘结性能。
