Problems solved by technology

However, the sodium β-sulfonate formaldehyde condensate is used therein, which makes the environmental protection performance not good; due to the poor synergy between the components, the amount of it is large, which affects the waterproof and anti-seepage performance and the mechanical strength of the concrete. The promotion effect needs to be further improved

Abstract

The invention discloses a concrete waterproof anti-cracking agent which is characterized in that the concrete waterproof anti-cracking agent is prepared from the following components in parts by weight: 3-6 parts of porous beta-cyclodextrin crosslinked polymer nano-fibers, 10-15 parts of bauxite powder, 4-7 parts of a sulfonic acid group-containing fiber material, 20-30 parts of alunite, 8-12 parts of blast furnace slag, 2-4 parts of rosin-based hyperbranched polyester, 5-10 parts of sulfonate modified 2-amino adenine nucleoside, 3-5 parts of nano-boron fibers, and 2-5 parts of surface hydrophilic pig hair fibers. The invention also provides a preparation method of the concrete waterproof anti-cracking agent. The concrete waterproof anti-cracking agent disclosed by the invention is remarkable in waterproof anti-cracking effect, small in mixing amount, capable of effectively improving the comprehensive performance of concrete and good in environmental protection property.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete waterproof and anti-cracking agent and a preparation method thereof. Background technique [0002] With the rapid development of the economy, my country's construction industry is also developing rapidly, and the use of concrete has also greatly increased. Concrete is referred to as "concrete" for short, which refers to the collective name of engineering composite materials that aggregate aggregates into a whole by cementitious materials. Concrete is one of the most important civil engineering materials in the contemporary era. It has the characteristics of abundant raw materials, low price and simple production process. At the same time, the hardened concrete has the characteristics of high compressive strength, good durability and wide range of strength grades. It is widely used in construction projects. [0003] Concrete is a hydraulic material. During ...
