Abstract

The invention discloses sulfate-corrosion-resistant waterproof mortar and a preparation method thereof. Comprising the following raw materials in parts by weight: 250-350 parts of nickel slag, 20-30 parts of carbide slag, 25-35 parts of sodium carbonate, 4-6 parts of basalt fiber, 5-7 parts of sodium lignin sulfonate, 40-50 parts of polyvinyl alcohol stabilized ethylene-vinyl acetate emulsion, 750-1050 parts of ferronickel tailings, 35-45 parts of water, 4-6 parts of an auxiliary agent, 1-6 parts of a water reducing agent and 1-2 parts of a defoaming agent. According to the sulfate-erosion-resistant waterproof mortar prepared by adopting a wet-grinding ultrafine mode and the preparation method, sulfate erosion of concrete can be effectively prevented, the mortar has excellent self-repairability and impermeability, coordination of body deformation is guaranteed, the materials are low in cost, easy to obtain and environmentally friendly, the operation process is simple and convenient, the preparation cost is effectively reduced, and the method is suitable for industrial production. And the method has obvious practicability and economical efficiency.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environment-friendly concrete materials, in particular to a sulfate-resistant waterproof mortar and a preparation method. Background technique [0002] Nickel slag is the waste slag produced in the smelting process of non-ferrous metal minerals. The scale of my country's non-ferrous metallurgical industry is huge. At the same time, the discharge and storage of non-ferrous metallurgical slag are large, but the utilization rate of non-ferrous metallurgical slag is very low. land resources, and caused serious pollution to the environment and groundwater. At present, the annual stockpiled nickel slag in my country is as high as 30 million tons, which has become the fourth largest smelting industrial waste after relaying slag, steel slag and red mud in the non-ferrous metallurgical industry. The main component of nickel slag is SiO 2 , CaO, Al 2 O 3 , Fe 2 O 3 , MgO, etc., of which SiO ...
