Description
技术领域 technical field
本发明涉及一种砌筑砂浆干粉料,尤其涉及一种利用蒸压粉煤灰加气混凝土废料制备的低成本砌筑砂浆干粉料。 The invention relates to a masonry mortar dry powder material, in particular to a low-cost masonry mortar dry powder material prepared by using autoclaved fly ash aerated concrete waste.
背景技术 Background technique
蒸压粉煤灰加气混凝土是一种具有墙体自保温的新型建筑墙材,主要以水泥、石灰、石膏、铝粉以及粉煤灰为原料,经过原材料制备、配料浇注、静养发气、坯体切割、蒸压养护、成品贮存等工序制成。蒸压粉煤灰加气混凝土最大优势就是原料的来源非常的广泛;并且有非常好的可加工能力、隔热、保温能力以及加工特性,可铇可锯。随着墙材革新工作的不断推进,蒸压粉煤灰加气混凝土砌块已逐渐在建筑工程中得到规模应用。 Autoclaved fly ash aerated concrete is a new type of building wall material with wall self-insulation. It mainly uses cement, lime, gypsum, aluminum powder and fly ash as raw materials. It is made by the processes of body cutting, autoclave curing, and finished product storage. The biggest advantage of autoclaved fly ash aerated concrete is that the source of raw materials is very wide; and it has very good machinability, heat insulation, heat preservation ability and processing characteristics, and can be sawed. With the continuous advancement of wall material innovation, autoclaved fly ash aerated concrete blocks have gradually been used in large-scale construction projects.
随着蒸压粉煤灰加气混凝土应用的广泛,在生产过程中,切割废料、搬运废料以及不合格品废料总量也日益增多,无处堆放、无地运出,给企业造成极大困扰,给环境带来污染。目前,蒸压粉煤灰加气混凝土废料利用技术主要有⑴将废料烘干与石膏混合制得膨胀剂;将该膨胀剂与硅酸盐水泥混合均匀,制得膨胀水泥;⑵由废碎渣、纤维材料及其它工业废料制成加气混凝土废碎渣墙体;⑶将面包头和废坯料作原料,可制成密实(或配筋)硅酸盐酸盐混凝土制品和密实硅酸盐瓦材产品,如果在湿热养护后进行表面处理,还可制成硅酸盐水磨石制品、铺地及贴墙用各色面砖;⑷利用废料去除废水中的磷。 With the wide application of autoclaved fly ash aerated concrete, in the production process, the total amount of cutting waste, handling waste and substandard product waste is also increasing day by day, and there is nowhere to stack and transport out, causing great troubles to enterprises , causing pollution to the environment. At present, the utilization technologies of autoclaved fly ash aerated concrete waste mainly include (1) drying the waste and mixing it with gypsum to obtain an expansion agent; mixing the expansion agent with Portland cement evenly to obtain an expansive cement; , fiber materials and other industrial wastes to make aerated concrete waste and slag walls; (3) use bread and waste billets as raw materials to make dense (or reinforced) silicate concrete products and dense silicate tiles If surface treatment is carried out after hot and humid curing, it can also be made into silicate terrazzo products, various colored tiles for paving and wall covering; (4) use waste to remove phosphorus in wastewater.
但是以上技术无法就地利用废料,并且废料利用率较低、废料利用技术不完善,会产生二次污染,所以其市场推广存在难度。如何妥善处理、有效利用蒸压粉煤灰加气混凝土废料并获得较高的社会效益、生态效益和经济效益是亟待解决的问题。 However, the above technologies cannot utilize waste on site, and the waste utilization rate is low, and the waste utilization technology is not perfect, which will cause secondary pollution, so its market promotion is difficult. How to properly handle and effectively utilize autoclaved fly ash aerated concrete waste and obtain higher social, ecological and economic benefits is an urgent problem to be solved.
