Problems solved by technology

[0005] However, the cost performance of foam concrete is low, and its strength is not high, it has a high water absorption rate, and the degree of shrinkage and cracking is also very serious.
Ceramsite concrete can alleviate this problem to a certain extent, but there are still some problems in ceramsite concrete: such as poor fluidity, many structural defects, and some pore structures are unreasonable, resulting in low thermal insulation performance.

Abstract

The invention discloses a ceramsite foam concrete and a preparation method thereof. The concrete consists of ordinary portland cement, ceramsite, fly ash, river sand, nano zeolite powder, albite, a composite foaming agent, a water reducing agent, carbon fiber, vanadium carbide, cellulose ether, triethanolamine and sodium dodecyl sulfate. In the invention, a ceramsite foam concrete and a preparation method thereof are developed by combining foam concrete and ceramsite concrete; and meanwhile, by optimizing the raw materials and content thereof, the concrete fluidity is improved, the pore structure distribution is optimized, and the thermal insulation property is enhanced.

Description

technical field [0001] The invention belongs to the field of concrete, in particular to a ceramsite foamed concrete. Background technique [0002] With the rapid development of my country's construction industry, my country's demand for building materials is also growing, especially concrete and related materials. [0003] Concrete, referred to as "concrete (tóng)": refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0004] Foamed concrete is the concrete that researches more now, discloses a kind of preparation method of foamed concrete as CN104446633A, and concrete steps comprise: take raw ma...
