Abstract

The invention relates to a preparation method of a concrete additive. The additive is composed of the following components in parts by weight: 6 to 12 parts of carboxylated graphene, 3 to 8 parts of zinc oxide powder, 4 to 7 parts of active carbon, 30 to 40 parts of nano level mild heavy calcium powder, and 40 to 50 parts of polyester fiber. According to the preparation, weighed carboxylated graphene, zinc oxide powder, active carbon, and nano level mild heavy calcium powder are delivered to a forced mixer to mix the components mentioned above, then according to the needs, the mixture is filled into bags, then weighed polyester fibers are added into the bags, and finally the bags are sealed to obtain finished products. The provided concrete additive can greatly enhance the anti-cracking and anti-seepage performance of concrete, moreover, the anti-rust performance of steel bar structure is greatly strengthened, and the waterproof period of buildings is largely prolonged.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a preparation method of a concrete 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, which seriously affects and restricts the application of concrete materials. [0003] Therefore, various additives related to impr...
