Novel light compression-resistant foam concrete and preparation method thereof

Abstract

The invention discloses novel lightweight compression-resistant foam concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by mass: 35-45 partsof cement, 25-30 parts of fly ash, 20-25 parts of lime powder, 12-18 parts of asbestos fiber, 10-20 parts of glass fiber, 2-5 parts of foaming agent, 1-3 parts of calcium stearate, 2-4 parts of polycarboxylic acid water reducing agent and 40-50 parts of water;. The compressive strength of the concrete is improved by adding the asbestos fibers and the glass fibers into preparation raw materials ofthe concrete, the concrete is high in compressive capacity, slurry can be evenly distributed in the mold by swinging the supporting plate and the mold, the slurry is scraped to be flat through the scraping plate, the surface of the prepared concrete can be smooth, the quality of the concrete is guaranteed, construction is facilitated, the concrete with different sizes can be leveled, and the applicability is high.

Description

technical field [0001] The invention relates to concrete, in particular to a novel light-weight compressive foam concrete and a preparation method thereof. Background technique [0002] Foamed concrete, also known as foamed concrete or lightweight concrete, foamed concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and mix the foam and cement slurry evenly, and then pass through the foaming machine It is a new type of lightweight thermal insulation material containing a large number of closed pores formed by natural curing through the pumping system for cast-in-place construction or mold molding; foamed concrete is made by mixing foaming agent, cement, fly ash, stone powder, etc. The double-set continuous structure polymer of organic binder contains uniform pores; foamed concrete is an energy-saving material used for roof insulation slope finding, ground insulation cushion, upturned beam foundation pit filling, and wall...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of novel lightweight anti-pressure foam concrete and preparation method thereof, foaming agent of the present invention is made of lauryl alcohol, alcohol ether glycoside, sodium lauryl sulfate, ammonium carbonate, makes the obtained The air bubbles in the concrete are uniform and sufficient, and the weight is relatively light. The invention improves the compressive strength of the concrete by adding asbestos fibers and glass fibers to the raw materials for concrete preparation, and solves the technical problem of poor compressive resistance of traditional foam concrete;
