Abstract

The invention relates to desulfurized gypsum based antistatic self-leveling mortar and its preparation method. Adopting calcined desulfurized gypsum as the main raw material, the desulfurized gypsum based antistatic self-leveling mortar comprises the following components by weight: 25-45 of desulfurized gypsum, 5-10 of slag powder, 3-10 of fly ash, 5-12 of portland cement, 15-25 of quartz sand, 15-25 of steel slag sand, 0.03-0.2 of modified carbon fiber, 0.5-2.0 of redispersible emulsion powder, 0.02-0.07 of cellulose ether, 0.10-0.25 of a water reducer, 0.1-0.4 of an antifoaming agent, 1.2-2.5 of an early strength agent, 0.02-0.06 of a retarder, and 0.002-0.005 of a carbon nanotube. The desulfurized gypsum based antistatic self-leveling mortar has good antistatic performance, bonding property, wear resistance, as well as high compressive strength, and overcomes the defect of poor water proofness of gypsum based materials. By utilizing a lot of industrial solid waste, the self-leveling mortar of the invention has the advantages of environmental protection, energy saving, and low cost, etc., and can be applied in various building ground projects with requirements for electrostatic protection and levelability.

Description

technical field

[0001] The invention belongs to the technical field of building materials and also relates to the technical field of functional materials, in particular to a desulfurized gypsum compounded by desulfurized gypsum, steel slag sand, fly ash, slag powder, carbon fiber, carbon nanotubes and chemical additives Base antistatic self-leveling mortar and preparation method thereof. Background technique

[0002] Energy conservation and comprehensive utilization of resources is a long-term strategic policy for my country's economic and social development. my country has proposed to develop a low-carbon economy based on low energy consumption, low pollution, and low emissions. One of the important components of the low-carbon economy is the secondary resource utilization of various wastes, especially industrial solid wastes. Desulfurization gypsum is a kind of solid waste produced in the process of flue gas desulfurization in coal-fired power plants. It takes up a lot o...
