Abstract

The invention provides a steel slag and slag high-performance composite grout, which comprises the following raw materials by weight proportion: 0 to 60 portions of steel slag, 0 to 60 portions of granulated blast-furnace slag, 20 to 60 portions of sulphoaluminate cement, 0 to 50 portions of Portland cement, 2 to 8 portions of air entraining agent and excitant, 0.5 to 10 portions of slag activity excitant, 3 to 10 portions of antisettle agent, and 10 to 15 portions of high-performance expanding agent; and the raw materials are evenly mixed. The grout has better durability and wearing resistance, and can save resources and reduce the emission of waste at the same time to achieve the aims of protecting the environment and reducing the cost.

Description

technical field [0001] The invention relates to a cement-based high-performance composite grouting material (hereinafter referred to as the grouting material). The aggregates and admixtures used are steel slag, granulated blast furnace slag and other wastes from metallurgical enterprises, thereby forming aggregates and cementitious materials. High performance composite grout without interface. Background technique [0002] Since the beginning of the 21st century, my country's iron and steel industry has developed rapidly, producing a large amount of waste steel slag and blast furnace granulated slag, which has caused huge pressure on the environment and is still growing at a rate of hundreds of millions of tons per year. How to effectively solve the comprehensive utilization of waste, reduce environmental pressure, and turn waste into wealth is an important issue for circular economy and sustainable development. Using steel slag and slag to make grouting materials has the a...
