Seepage-prevention anti-shearing heat-insulating hollow building block

Abstract

The invention relates to a seepage-prevention anti-shearing heat-insulating hollow building block which is characterized by comprising the following components by weight percent: 71.8-54.7 percent of Mo-bearing iron ore tailing slag containing silicon oxide of over 60, 15-30 percent of fly ash ceramsite, 10-8.5 percent of cement, 3.2-6.8 percent of fly ash of over two grade and 4-3.5 percent of water. Because the voidage of the hollow building block reaches about 50 percent, the dry density is decreased to be 1000-850 kg / m3 similar to that of aeroconcrete of 620-850kg / m3. The granularity of the Mo-bearing iron ore tailing slag and the fly ash ceramsite is supposed to be less than or equal to 12mm after pulverization and treatment. In the structure of the hollow building block, the left and the right end surfaces of the block are respectively provided with a shearing groove and a groove tenon which are capable of being matched with each other for firm tenon joint, the upper and the lower planes are prefabricated with seepage prevention grooves and seepage prevention tenons, which are capable of matched with each other for firm tenon connection, so that the performances of seepage prevention, shearing resistance, thermal insulation and the like are improved overall. With the seepage-prevention anti-shearing tenon-groove cooperation, the construction has a hard standard for standardizing wall building, and a high wall can be built directly, so that the hollow building block is a perfect product.

Description

Technical field: [0001] The invention belongs to the field of building materials, and in particular relates to an anti-seepage, anti-shear and heat-insulating hollow block mainly made of molybdenum iron ore tailings and fly ash waste. Background technique: [0002] At present, new wall materials have been developed and applied in the market, but there is no series of products with excellent performance to replace the clay solid bricks and hollow bricks handed down for thousands of years from "Qin bricks and Han tiles"; in the eyes of Chinese people Traditional clay brick products are all excellent and are the supreme luxury. So far, any new type of wall material can't shake its superior position, and it seriously challenges and puzzles industry experts, design institute engineers and "ban" workers. [0003] Why can't clay solid bricks and hollow bricks be replaced? Aerated concrete products made of various material formulas are light in weight, but due to moisture absorpti...

Problems solved by technology

It is observed that in some small and medium-sized cities, in order to cater to the psychology of home buyers, some developers quietly use clay hollow bricks with better texture. They would rather pay more for the "new wall material fund" than use new wall materials; However, it is still the main wall material in the construction industry; especially the hundreds of millions of peasants still use clay solid bricks, and they have a soft spot for clay products
