Method for preparing foaming concrete lightweight wall material

Abstract

The present invention discloses a foam concrete light wall-body material and the corresponding preparation method; the detailed preparation method is that: the components in the present invention such as water, common cement and medium sand (powder coal ash or industrial cinder) are added into a milling pot to be milled evenly and enough according to weight ratio with 0.8 : 1: 1 of water: common cement: medium sand; and the components in the foam agent includes rosin, sodium hydroxide and glue agent; according to the weight ratio with 15 : 1: 18 of rosin : sodium hydroxide : glue agent, the rosin, sodium hydroxide and glue agent are added into a container to be milled evenly and enough to obtain the foam agent. And then the foam agent and the water with the weight ratio of 1: 50 are respectively added into a foam pot; the pressure is increased to 8kg to the foam pot by a common air pump; the foam agent in the pressure situation is ejected into the milling pot of the concrete by a foam gun and then to be milled evenly and enough. The foam concrete can be obtained after the foaming process is stable, and then the foam concrete is ejected into a mould; the mould can not be dismantled until the natural conservation reaches the intension requirement of the dismantlement. Finally, after being maintained in 25 DEG C for 8 hours, the foam concrete light wall-body material with the density of 700- 900kg / m3 can be obtained.

Description

technical field [0001] The invention relates to a preparation method of a foamed concrete lightweight wall material, which belongs to the manufacturing technology of building materials. Background technique [0002] Chinese patent application No. 200510047439.0 discloses a "manufacturing method of foamed concrete lightweight wall material on site", which is to mix hydrogen peroxide with water with 5-10% of water quality, and then mix aluminum with 2-7% of cement quality. Mix the powder with cement, sand, and stone evenly; then mix the above two mixtures, stir and pour them into the built formwork; after 4 hours (20°C), the concrete will foam in the formwork and form strength, until the strength reaches the formwork removal requirements Finally, the formwork is removed, and after curing, the final density is 1800-2100kg / m 3 of the wall. The foamed concrete that this method makes, its density is still very big, and sound insulation effect is still not good enough, and the la...

Problems solved by technology

The foamed concrete produced by this method still has a high density, and the sound insulation and heat preservation effect is still not good enough, and the labor intensity during use is still relatively high.
