Naturally-foamed non-autoclaved novel wall block

Abstract

The invention relates to a naturally-foamed non-autoclaved novel wall block and belongs to building materials. The naturally-foamed non-autoclaved novel wall block is processed from following raw materials in parts by weight: 50-60 parts of base stock, 10-20 parts of magnesium oxide dry powder, 10-15 parts of magnesium sulfate dry powder, 10-15 parts of magnesium chloride dry powder, 2-4 parts of hydrogen peroxide and 1-3 parts of phosphoric acid. A processing process of the naturally-foamed non-autoclaved novel wall block comprises the following steps of: firstly crushing the base stock, adding water and mixing the base stock with the magnesium oxide dry powder, the magnesium sulfate dry powder and the magnesium chloride dry powder, stirring at the normal temperature, carrying out sample examination, adding hydrogen peroxide and the phosphoric acid, continuously stirring, pouring the mixture in a mold, then foaming, maintaining and demolding, so as to obtain the finished wall block. The naturally-foamed non-autoclaved novel wall block has the advantages that the manufacturing is simple, the cost is low, and a large amount of coal ash, tail sand, sludge, blowing sand, household garbage or industrial residue is reasonably and comprehensively utilized, so that the problems such as waste of resources and environmental pollution are solved.

Description

technical field [0001] The invention relates to a preparation method of building materials, in particular to a new type of naturally foaming and steam-free wall block. Background technique [0002] With the continuous development of urban buildings, in order to save space and reduce loads, non-load-bearing walls in various construction projects generally use lightweight wall blocks. At present, there are many types of lightweight wall blocks on the market, such as autoclaved aerated block bricks, hollow block bricks, etc.; the material requirements in the production process of autoclaved aerated block bricks are complicated, and steam is required for maintenance. It is a mature technology, but its production of finished products requires a large investment in building a factory; while hollow block bricks need to consume a large amount of cement, river sand and maintenance turnover sites. From the user's point of view, the above-mentioned lightweight wall blocks prepared by ...
