Preparation method of foam concrete based on plant-based foaming agent

Abstract

The invention relates to the field of preparation of building materials, in particular to a preparation method of foam concrete based on a plant-based foaming agent. According to the invention, the plant-based protein foaming agent is used as the foaming agent of the foam concrete so that the prepared concrete has better impermeability and excellent thermal insulation capability, and the compressive strength of the concrete is not lower than other foam concrete; according to the invention, the modified diatomite is added into the aggregate of the foamed concrete so that the aggregate has goodthermal insulation and sound insulation properties, and the aggregate and closed pores have good thermal insulation and sound insulation properties; the plant-based protein foaming agent is prepared by heating and hydrolyzing sunflower cake meal and lotus pond sludge in the presence of calcium oxide, the foaming agent is prepared by taking high-quality natural plants as raw materials and is odorless, non-toxic and harmless, is not sensitive to hard water, does not generate precipitates, does not corrode concrete and metals, and does not pollute the environment; and the prepared foam concrete has excellent quality.

Description

technical field [0001] The invention relates to the field of building material preparation, in particular to a method for preparing foamed concrete based on a plant-based foaming agent. Background technique [0002] Foamed concrete is usually mechanically prepared from an aqueous solution of a foaming agent into a foam, and then the foam is added to a slurry composed of siliceous materials, calcium materials, water and various admixtures, etc., after mixing, pouring, A porous material formed by curing. Because the foamed concrete contains a large number of closed pores, it has many good physical and mechanical properties such as low density, excellent thermal insulation performance, good sound insulation effect, and good shock absorption performance. [0003] CN105294153A discloses a foamed concrete, which is made of the following raw materials in parts by weight: 3-6 parts of zinc sulfate, 6-10 parts of carbon powder, 7-9 parts of calcium carbonate, 20-40 parts of cement, ...

AI Technical Summary

Problems solved by technology

[0006] The key to foamed concrete lies in the performance of the foaming agent. At present, two types of foaming agents, rosin soap and rosin thermal polymer, are used more in the market in my country, as well as high-quality foaming agents imported from developed countries such as Italy, Japan, South Korea, and the United States. Performance protein foaming agent, my country is also developing some protein foaming agents, but the internal pores of the foamed concrete made of protein foaming agents are connected, so the thermal insulation performance and compressive strength are not good, so our country is completely independent The development of foamed concrete produced has been limited
