Abstract

The invention provides polymer modified nickel slag waterproof mortar and a preparation method thereof. The polymer modified nickel slag waterproof mortar is prepared from the following components in parts by weight: 60 to 80 parts of nickel slag powder, 20 to 40 parts of carbide slag, 2 to 5 parts of sodium sulfate, 40 to 50 parts of organic silicon modified epoxy emulsion, 10 to 16 parts of glass powder, 40 to 60 parts of water, 4 to 6 parts of auxiliaries, 4 to 6 parts of water reducing agent, 0.4 to 0.6 part of defoaming agent and 180 to 240 parts of ferronickel tailings. The waterproof mortar prepared by the invention has the advantages of high impermeability grade, high bonding strength and compressive strength, good flexibility, wear resistance, fluidity and impact resistance, easily available and cheap raw materials, convenient construction and simple preparation method. The nickel slag is used as a binding material, the industrial by-product carbide slag is used as an exciting agent, and the ferronickel tailings replace fine aggregate, so that the resource reutilization of wastes is realized, the energy waste of'two-grinding and one-burning 'of the cement is effectively avoided, and the method is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly building materials, and in particular relates to a polymer-modified nickel slag waterproof mortar and a preparation method thereof. Background technique [0002] Nickel is a non-ferrous metal of strategic significance, widely used in the military and defense industries, and nickel is also an essential component for the production of stainless steel. However, the nickel content of nickel ore is very low, and even fine ore after beneficiation can only reach 6%-12%, and the slag produced after smelting reaches 80%-90% of the raw material quality. The solid waste slag produced in the process of extracting metallic nickel, currently, the annual increase of nickel slag in my country has reached 30 million tons, and it has developed into the fourth largest smelting industry waste slag after slag, steel slag and red mud. Due to the high difficulty in handling nickel slag and...
