Abstract

The invention discloses dry-process desulphurized fly ash dry-mixed mortar, which belongs to the field of pre-agitated dry-mixed mortar materials for buildings. The mortar is formed by mixing the following materials in a ratio by weight: 8-12 parts of cement, 15-20 parts of dry-process desulphurized fly ash, 68-77 parts of aggregate, 0.25-0.4 part of composite excitant, 0.07-0.1 part of compositewater retaining agent, 0.2-0.3 part of composite anti-cracking agent and 0-0.3 part of water repellent agent. Compared with the prior art, the dry-process desulphurized fly ash dry-mixed mortar adopts extremely fine ash formed by a dry-process desulfurizing technology as a main material and has the characteristics of energy saving, environment friendliness, low material cost and the like.

Description

technical field [0001] The invention relates to a ready-mixed dry-mixed mortar material for construction, in particular to a dry-process desulfurized ash dry-mixed mortar. Background technique [0002] At present, there are three main types of gas desulfurization processes for coal-fired boilers in my country: wet desulfurization process, semi-dry desulfurization process, and dry desulfurization process. Baosteel alone produces 170,000 tons of desulfurization ash every year. In the existing technology, there are some relatively mature utilization methods for calcium sulfate dihydrate produced by wet desulfurization process, but there is basically no mature utilization method for desulfurization ash. . [0003] On the other hand, with the development of society, people's requirements for project quality, environmental protection requirements and civilized construction are constantly improving, and the advantages of dry-mixed mortar are favored by more and more people.
