A kind of ceramsite concrete and preparation method thereof

Abstract

The application discloses a ceramsite concrete and a preparation method thereof, and relates to the technical field of building materials. A ceramsite concrete is mainly made of concrete raw materials including the following parts by weight: 50-75 parts of cement, 35-55 parts of water, and 200-250 parts of sand; the concrete raw materials also include admixtures and modified lightweight materials , the external material includes 0.5-2.5 parts by weight of water reducing agent; the modified lightweight material is mainly made of modified raw materials including the following parts by weight: 0.5-1.8 parts of aminopropyl triethoxysilane, fat 0.3-0.9 parts of amine polyoxyethylene ether, the modified raw material also includes a modified matrix, and the modified matrix includes 45-90 parts by weight of ceramsite. Ceramsite concrete has the advantage of good crack resistance. The preparation method includes the following steps: mixing and concrete preparation. The preparation method has the advantage of improving the crack resistance of the product.

Description

A kind of ceramsite concrete and preparation method thereof technical field The application relates to the technical field of building materials, in particular to a kind of ceramsite concrete and preparation method thereof. Background technique Concrete takes cement as main cementitious material, and is matched with water, sand, ceramsite, admixtures and mineral admixtures. The artificial stone is made of uniform stirring, compact forming and curing and hardening. Concrete has the advantages of high hardness and convenient construction. Widely used in construction field. With the development of society, people's requirements for buildings are gradually increasing, and concrete is gradually becoming lighter. qualitative development. Ceramsite concrete has the advantages of light weight, good thermal insulation performance and excellent fire resistance, and has gradually been widely used. use. CN108793888A discloses a kind of ceramsite concrete wallboard and prepa...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that ceramsite has high water absorption rate and low density, which will easily accelerate the loss of slump, affect workability, and easily cause problems such as bleeding and segregation, which will bring certain problems to the crack resistance of ceramsite concrete.
