Problems solved by technology

[0006] 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 ceramsite foamed concrete which is composed of ordinary Portland cement, ceramsite, fly ash, river sand, nano zeolite powder, albite, composite foaming agent, water reducing agent, carbon fiber, vanadium carbide, cellulose ether, triethanolamine and sodium lauryl sulfate. The ceramsite foamed concrete is prepared by combining foamed concrete and ceramsite concrete; at the same time, by the optimization of the composition of the raw materials and contents thereof, the fluidity of the concrete is improved, the pore structure distribution is optimized, and the heat insulation performance is improved.

Description

[0001] This application is a divisional application of a patent with an application number of 2016101097431 and an application date of February 29, 2016, entitled "a kind of ceramsite foamed concrete and its preparation method". technical field [0002] The invention belongs to the field of concrete, in particular to a ceramsite foamed concrete. Background technique [0003] 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. [0004] 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. Concr...
