The invention discloses a preparation method of fly ash blind hole hollow brick, which belongs to the field of building brick manufacturing method, especially relates to a manufacturing method of all fly ash blind hollow brick; the invention is mainly aimed at the existing extrusion moulding of fly ash sintered brick waste of energy and waste of natural resources and cost high, only the production of through hole hollow brick, brick masonry wall strength is not high, easy to crack the problem, provide a comprises the following steps: pretreatment A. small amount of fly ash; B. adding fluxing additive; adding C. residual fly ash; D. forced mixing; e. compression molding; method of preparation of F. sintered fly ash. The weight of the brick group was 98% higher than the content; compared with the existing manufacturing method of the invention of extrusion molding of fly ash sintered brick, has the advantages of saving natural resources. The utility model has the advantages of energy saving and low cost, and can produce high quality and high strength blind hole hollow bricks.
【技术实现步骤摘要】
本专利技术属于建筑用砖的制作方法领域，特别涉及一种。
技术介绍
目前建筑物用烧结砖为粘土砖、页岩砖、矸石砖、粉煤灰砖。现有的粉煤灰烧结砖多是将粉煤灰掺入粘土中，经搅拌、挤塑成型、烘干、烧结而成。用粘土做粘合物，挤塑成型存在三大不足一是粉煤灰不易与粘土充分拌合，增加了生产工艺难度，生产过程中电耗高，还要内掺外投燃料，能源浪费大，成本高；二是为了保证挤塑成型，粉煤灰掺合比例较低，一般体积比在20％～50％左右，加大了粘土的用量，浪费了自然资源；三是只能生产通孔空心砖，砌体强度难保证，墙面易产生裂纹。
技术实现思路
本专利技术的目的是为了克服现有粉煤灰烧结砖制作方法存在的上述不足，提供一种可以节约能源，降低成本，减少自然资源的浪费，治理电厂对环境的污染和堆积粉煤灰占用土地，生产出优质高强度盲孔空心砖的。本专利技术的目的是通过下述技术方案来实现的，所述砖的组成成分的重量比为，粉煤灰96％～98％，助熔添加剂2％～4％，制作方法包括如下步骤，a.少量粉煤灰预处理；b.添加助熔添加剂；c.添加余量粉煤灰；d.强制搅拌；e.加压成型；f.烧结。助熔添加剂主要成分为含钾的矿物，或...
