Problems solved by technology

[0004] Steel slag is one of the main waste slags in the iron and steel industry. The comprehensive utilization rate of steel slag in my country is small. A large amount of steel slag accumulation not only occupies land and pollutes the environment, but also is a great waste of resources.

Abstract

The invention belongs to the technical field of building materials, in particular relates to a quick-hardening early-strength structure reinforcement material based on aluminate cement and steel slag. The structure reinforcement material consists of aluminate cement, steel slag, ore slag powder, fly ash, silicon ash, a retarder, a water reducing agent, a latex powder, cellulose ether, a defoamer and poval fiber. By using the material provided by the invention, the problems of the common cement-based reinforcement material, such as high construction difficulty, long wet operation time and low early strength, can be solved. According to the invention, a composite gel material supplemented by steel aggregate, a composite additive and fiber is subjected to dry mixing and then packaged for supply; in scene, the structure reinforcement material provided by the invention can be used after adding water and stirring; and the structure reinforcement material has the characteristics of high early strength, good cracking resistance, good permeability resistance, small shrinkage, excellent durability and the like, is easy to construct and is suitable for reinforcing works of buildings, wharfs, bridges, dams, railways, tunnels and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a fast-hardening and early-strength structural reinforcement material based on aluminate cement and steel slag. Background technique [0002] Concrete is the most widely used and applied building material in the world today. Due to the low tensile strength of concrete, large dry shrinkage, poor toughness, coupled with the influence of changing environment, poor construction quality or improper design, concrete often suffers from diseases and shortens its service life. In order to prolong the service life of concrete buildings, it is necessary to repair and strengthen the concrete structures that have been damaged. [0003] Concrete structure reinforcement materials mainly include cement-based reinforcement materials, steel and welding materials, fiber and fiber composite materials, adhesives and rust inhibitors, among which cement-based reinforcement materials are the...
