Cellular concrete product

Abstract

A foamed concrete product is characterized in that Portland cement or ordinary Portland cement is taken as gelling material; zeolite powder, metakaolin powder, limestone powder, fly ash or silicon ash powder are taken as admixtures; protein hydrolysate of hoof and horn of animals is taken as a foaming agent; an acrylate coagulator or a polycarboxylic acid type water reducing agent is taken as an adjuvant, and water is active water. In order to improve the early strength, the later compressive strength, the bending strength and the anti-tensile splitting strength of the low-density foamed concrete, a plurality of admixtures comprising the zeolite powder, the metakaolin powder, the silicon ash powder or the limestone powder are chosen, by mutual collocation of the components and contents of the admixtures, the comprehensive improvement of various strengths is achieved, and the multifunctional effects of insulating heat, adjusting moisture, preserving heat, and the like, are obtained. In the foamed concrete blocks of the ordinary Portland cement, the density is 500-800kg / m<3>, the compressive strength is 6-8MPa and the water absorption rate is 5-10%, the heat preserving property and the heat insulating property are obviously improved, the water absorption performance and the moisture adjusting index are remarkably improved, and the better cost performance ratio is obtained.

Description

technical field [0001] The invention relates to a building material, especially a cement foam concrete product. Background technique [0002] At present, the domestic construction industry is gradually reforming wall materials, and various blocks with perforated structures have gradually replaced traditional wall bricks, which have achieved remarkable results in reducing the weight of buildings, increasing floor heights, and expanding the use area. With the progress of society and the further improvement of people's housing conditions, modern building structures put forward higher requirements for building materials. For example, the wall structure requires not only to reduce the weight of the wall, but also to have high strength and good seismic performance, which is both thermal insulation and insulation. heat to save energy. In order to adapt to this development trend, the construction industry at home and abroad has achieved remarkable results in the production of foam-...
