Foam concrete additive and foam concrete

Abstract

The invention discloses a foam concrete additive, which comprises the following components in percentage by mass: 3.5 percent of lauryl sodium sulfate, 0.8 percent of lauryl dimethyl amine oxide, 5 percent of thickening agent, 5 percent of sodium silicate, 0.3 percent of water reducing agent and 85.4 percent of water. The invention also discloses foam concrete, which comprises the following components in percentage by mass: 15 to 17 percent of cement, 10 percent of fine sand, 50 percent of coal ash, 20 percent of water and 3 to 5 percent of additive which is diluted by water in a ratio of 1:35. The foam concrete additive and the foam concrete are high in adaptability to the cement; and the foam concrete is high in strength, bulking rate and foam stability, non-toxic, tasteless, difficult to decompose and convenient to store and transport, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of foam concrete, in particular to a foam concrete additive and foam concrete. Background technique [0002] For building wall materials, its performance indicators are mainly weight, strength, thermal insulation, sound insulation, etc. For the requirements of building energy conservation and environmental protection, wall materials are required to be light in weight, high in strength, thermal insulation, and sound insulation. The foam concrete can better meet the above conditions. After the concrete is expanded, the thermal insulation and sound insulation performance indicators are greatly improved, and the weight per unit volume can also be reduced to less than one-third of the concrete. [0003] In the production of foamed concrete in the prior art, the added additives (foaming agents) are divided into plant type and animal type. In practical application, plant-based additives will make the strength of foam conc...

Problems solved by technology

In practical applications, plant-based additives will make the strength of foam concrete insufficient, and the foam effect will not be stable at the same time, sometimes resulting in insufficient expansion rate and uneven foam, which will directly affect the u
