Production process of concrete additive

Abstract

The invention discloses a production process of a concrete additive. The production process comprises the following steps: S1, raw material preparation: selecting raw materials in parts by weight: 5 to 18 parts of magnesium silicate, 10 to 20 parts of modified cement, 5 to 18 parts of fly ash, 8 to 30 parts of mineral powder, 6 to 20 parts of soil, 18 to 42 parts of quartz sand, 0.5 to 3 parts of KH550 silane coupling agent, 4 to 16 parts of acrylic acid, 14 to 50 parts of ethylene-vinyl acetate copolymer, 1 to 4 parts of fiber, 5 to 12 parts of efficient water reducing agent, 1 to 4 parts of reinforcing agent, 0.4 to 2.4 parts of cross-linking agent, 0.5 to 3.6 parts of free radical initiator, 0.2 to 1.4 parts of antioxidant, 0.1 to 1.2 parts of compound waterproof agent, 1 to 3 parts of ferric oxide and 0.2 to 0.6 part of an ultraviolet light absorber; S2, preparing modified inorganic filler powder; S3, preparing an intermediate material; S4, preparing a mixture; and S5, preparing the concrete additive. The additive disclosed by the invention has the advantages of good waterproofness, no need of high-temperature sintering, low energy consumption and convenience in raw material acquisition, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete additives, and in particular relates to a production process of concrete additives. 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 , in the production of concrete, concrete additives will be added, but there are still various problems in the production process of various concrete additives on the market. [0003] For example, the authorized announcement number is CN103755216A, which discloses a method for preparing con...

Problems solved by technology

[0003] For example, the authorized announcement number is CN103755216A, which discloses a method for preparing concrete composite additives. Although it realizes that the production process is not complicated, it is simple and easy to produce products, and it is convenient and can be used evenly in the use process, which meets the stability of production and ensures the production of concrete. quality, but it does not solve the existing problems of the existing concrete additive production process: it is inconvenient to improve the impermeability of concrete, it is inconvenient to improve the fluidity of concrete during mixing, and it is inconvenient to obtain raw materials, which reduces work efficiency. Therefore, we propose a production process for concrete additives
