Problems solved by technology

[0005] This is a common foam concrete component currently on the market, but research has found that most of the materials used in this type of foam concrete formula are hydrophilic or water-collecting substances; water is absorbed into the interior of the concrete by these materials and cannot flow away in time. As a result, the gelled slurry inside the concrete is softened by water bubbles. The overall structure of the foamed concrete after soaking in water is like tofu. After being subjected to a large external force, part of the structure in the concrete falls off, and the strength of the concrete structure is low.

Abstract

The invention relates to a foam concrete formula and a preparation method and application thereof. The foam concrete formula comprises 1-3 parts of a component A, 40-60 parts of a component B and 3-12parts of a component C, wherein the component A comprises vinyl acetate, polyvinyl alcohol, sodium lauryl sulfate, octanol, xanthan gum, propolis and saccharomycetes; the component B comprises cement, sand, gravel and mineral powder; the component C comprises a diluent. Foam concrete provided by the invention has relatively good hydrophobicity, so that water does not remain in a concrete system,and thus damage, caused by long-term retention of water in the concrete system, to a concrete structure is avoided; in the concrete formula provided by the invention, no admixture is used, and the concrete can be reused after being crushed, namely recycling of the concrete is achieved, so that the advantages of waste utilization and the like are achieved.

Description

technical field [0001] The invention relates to concrete, in particular to a formula of foam concrete and its preparation method and application. Background technique [0002] Concrete is a composite material composed of filler and cementitious material; in concrete, the filler acts as a skeleton and becomes aggregate, and the cementitious material and water form a slurry, which is called cementitious slurry; cementitious slurry Wrapped on the surface of the aggregate and fill the pores between the aggregates; before hardening, the gelled slurry acts as a lubricant, making the mixture have a certain degree of workability, which is convenient for construction; after the gelled slurry is hardened, the bone The material is hinged as a solid whole. Concrete can be divided into different types such as lime concrete, gypsum concrete, asphalt concrete, polymer concrete, foam concrete, etc. [0003] Foam concrete, also known as foam cement, lightweight concrete, etc., is a new typ...
