Embodiment Construction

[0012] The invention discloses a preparation process of thermal insulation foam concrete using andesite rock powder. The raw materials in the process include 520 parts by weight of water, 300 parts by weight of cement, 420 parts by weight of fly ash, 420 parts by weight of andesite powder and 310 parts by weight of activator mixed solution; the preparation steps are:

[0013] Water, portland cement, fly ash, andesite rock powder are fed into the mixing tank in proportion through the cement hopper and water pump, and stirred into cement slurry; the activator and water forming the activator mixed liquid are pressed The weight ratio of 10:300 is well stored in the barrel. The compressed air and the activator mixture are mixed through the foaming machine through the air compressor to form high-density bubbles. The pressure of the air pump needs to reach 0.8Mpa; and then through the hydraulic pressure of the foaming machine Mix the cement slurry and high-density air bubbles in the ...

Abstract

The invention relates to a thermal insulation foam concrete preparation process applying andesite rock powder. The raw materials comprise: 520 parts by weight of water, 300 parts by weight of cement, 420 parts by weight of fly ash, 420 parts by weight of andesite rock powder, and 310 parts by weight of an activator mixed solution. The preparation steps include: stirring water, Portland cement, fly ash and andesite rock powder into a cement slurry according to the proportion; preparing the activator mixed solution from an activator and water in a weight ratio of 10:300, placing the mixed solution in a bucket, mixing compressed air with the activator mixed solution through an air compressor and a foaming machine to form high density bubbles, making the pressure of an air pump reach 0.8MPa; and then mixing the cement slurry with the high density bubbles in a stirrer through the hydraulic pressure of the foaming machine, and finally delivering the product to a specified place through a high pressure pipeline. The thermal insulation foam concrete involved in the invention can completely replace ceramsite concrete, expanded perlite and other traditional thermal insulation and filling materials, can realize continuous casting construction on the spot, and is convenient, fast, economical, and environment friendly. The thermal insulation foam concrete prepared by the invention can be widely applied to roof sloping, leveling, thermal insulation, basement bottom plates, tops plates, bridges and many other fields.

Description

technical field [0001] The invention relates to the field of building technology and building materials, in particular to a preparation process of thermal insulation foam concrete using andesite rock powder. Background technique [0002] At present, a large amount of foam concrete is used for roof slope finding, insulation, and filling. Traditional foam concrete is produced with a large amount of cement, and the overall cost is high. [0003] Andesite is a kind of igneous rock and is one of the excellent aggregates for making concrete. The main waste of the quarry - stone powder, pollutes the environment, farmland and rivers. For the comprehensive utilization of resources, combined with the characteristics of andesite itself, this kind of stone powder is applied to the preparation of foam concrete. Contents of the invention [0004] The object of the present invention is to provide a kind of heat-insulating foam concrete preparation technology that uses andesite powder, ...
