Abstract

The invention discloses a dry-mixed mortar containing sintered dry desulfurization ash and recycled water plant sludge and a preparation method thereof, and solves the technical problem of high manufacturing cost of the existing dry-mixed mortar. According to the technical scheme, the dry-mixed mortar containing sintering dry desulfurization ash and recycled water plant sludge comprises the following raw material components in percentage by mass: 20 to 28 percent of sintering dry desulfurization ash, 30 to 40 percent of recycled water plant sludge, 20 to 28 percent of sand, 10 to 12 percent ofcement, 6 to 7 percent of fly ash, 1 to 3 percent of nano aluminum powder and 0.1 to 0.6 percent of sodium sulfate, wherein the sum of the mass percentages of all the raw material components is 100 percent. The dry-mixed mortar provided by the invention is simple in preparation process and low in production cost, so that the invention achieves value-added utilization of sintered dry-process desulfurized ash, recycled water plant sludge and fly ash.

Description

technical field [0001] The invention relates to a dry powder mortar, in particular to a dry powder mortar containing sintered dry desulfurization ash and recycled water plant sludge and a preparation method thereof, which belongs to the field of comprehensive utilization of dry powder mortar and solid waste resources in the field of building materials. Background technique [0002] In the field of building materials, compared with masonry mortar, dry powder mortar has the following characteristics: ①The plastering layer does not bear load; ②The plastering layer and the base layer must have sufficient bonding strength, so that it can be used during construction or long-term. It will not fall off or crack under the influence of the environment; ③The plastering layer is mostly a thin layer, and it is applied in layers. [0003] In order to ensure the workability, sag resistance, early strength, and construction convenience of dry-mix mortar, and facilitate the improvement of ma...
