Abstract

The invention relates to a concrete anti-cracking and anti-permeability special additive, which is composed of the following components in parts by weight: 9 to 11 parts of carboxyl material that is prepared by mixing sodium carboxymethyl cellulose and carboxylated graphene according to a mass ratio of 1:7.2-8.2, wherein sodium carboxymethyl cellulose and carboxylated graphene are both powder with a particle size of 500 to 600 meshes; 4 to 6 parts of zinc oxide with a particle size of 300 to 400 meshes; 4 to 5 parts of active carbon powder with a particle size of 200 to 300 meshes; 40 to 42 parts of nano level light heavy calcium carbonate powder with a particle size of 1000 to 1200 meshes, and 65 to 68 parts of polyester fiber with a length of 10 to 15 mm and a diameter of 20 to 25 [mu]m. The provided concrete special additive can largely improve the anti-cracking and anti-permeability performance of concrete, and thus the waterproof protection period of building is largely prolonged.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete anti-crack and anti-seepage special additive, and also relates to a preparation method of the concrete anti-crack and anti-seepage special additive. Background technique [0002] Concrete, referred to as "concrete" for short, usually refers to using cement as the cementitious material, sand and stone as the aggregate, mixed with water in a certain proportion, and mixed. Concrete has the characteristics of rich raw materials, low price and simple production process, which makes it widely used. It is not only used in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material . However, due to the characteristics of its own structure, concrete materials often leak during use, especially for those underground and underwater structural projects, whic...
