Concrete cracking resisting waterproofing agent

Abstract

The invention relates to a novel concrete cracking resisting waterproofing agent and particularly relates to an aluminum-slag-powder concrete cracking resisting waterproofing agent which is prepared from aluminum slag powder, steel slag powder, mineral slag, fly ash and a small amount of admixture, wherein the aluminum slag powder, the steel slag powder, the mineral slag and the fly ash serve as the raw materials. The aluminum slag powder accounts for 0.3-0.7%, the steel slag powder accounts for 10-30%, the mineral slag accounts for 20-70%, the fly ash accounts for 5-20% and the admixture accounts for 1-3%, wherein the total percent by weight of the components is 100%. The concrete cracking resisting waterproofing agent is low in construction cost and can be used to maintain easily, and the mixing amount of components of the concrete cracking resisting waterproofing agent is easy to control.

Description

technical field [0001] The invention relates to the technical field of auxiliary materials for building materials, in particular to a concrete anti-cracking and waterproofing agent. Background technique [0002] With the acceleration of urbanization, people have higher and higher requirements for the safety and reliability of buildings. Concrete is the main building material. The strength and durability of concrete directly affect the quality of buildings, and the quality of buildings is closely related to the quality of residents. Safety and satisfaction go hand in hand. Concrete, as a heterogeneous brittle material, often suffers from shrinkage and cracking, especially in the construction of reinforced concrete. Concrete shrinks after setting and hardening, and cracking occurs due to the restraint of steel bars, which seriously affects the durability of concrete. To solve this phenomenon, people have successively adopted the method of adjusting the mix ratio of concrete,...

Problems solved by technology

However, the existing anti-cracking and waterproofing agents need to add expansion agents, fibers, etc. when used, and the construction cost is high; the construction requirements of expansion agents need to be in a humid environment to achieve the effect, and the environmental requirements are relatively high during construction, which is not easy to achieve in general construction environments Construction requirements, concrete is affected by this and causes increased shrinkage; fibers tend to form agglomerates and are not easy to mix evenly during use. Increase the amount of fiber, so that the amount is not easy to control and the strength decreases
