Attapulgite- slate- fire-proof ceramsite hollow block

Abstract

The invention discloses an attapulgite-slate- fire-proof ceramsite hollow block. The key point of the technical scheme is that the hollow block comprises the following materials: attapulgite clay tailing, slates, high bauxite, spheroidal attapulgite fire-proof ceramsite, a volcaniclastic rock mixture, bentonite tailing powder, aluminate cement, a polypropylene reticular fiber and a polycarboxylic acid high-performance water-reducing agent. According to the method, the materials are uniformly stirred and pressed to a semi-manufactured product of the hollow block, which is subjected to regular maintenance for 28 days, and then is packed so as to form the finished product of the hollow block provided by the invention. The hollow block provided by the invention has the advantages of high strength, crack prevention, heat preservation, energy conservation, sound insulation, heat insulation, water absorption of not more than 20 percent, and good freeze-proof performance. According to invention, as the materials including a large amount of various wastes are utilized, not only the resource utilization rate is improved, wastes are changed into value of things, but also the land occupation is reduced, the environment is protected and purified, and the energy is saved. Therefore, the hollow block provided by the invention is suitable for wall construction.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an attapulgite shale refractory ceramsite hollow block. Background technique [0002] New wall materials mainly refer to building materials mechanized from non-clay resources such as sandstone, shale, industrial solid waste, and construction residual soil, which have the functions of protecting land, protecting the environment, saving energy, utilizing waste, increasing strength and economical Applicable and other characteristics, various concrete blocks are widely used in construction projects, but due to product quality, building structure, construction technology and other reasons, cracking of concrete blocks is common. For a long time, concrete masonry cracking, hollowing, Leakage is considered a common problem in wall construction. [0003] Shale is a rock formed by the extrusion of clay in the crustal movement. It has sheet-like or thin-sheet bedding. It is easy to break ...

Problems solved by technology

[0008] The disadvantage of the above-mentioned patent is that "the raw materials are mixed according to the following parts by mass on a dry basis: shale, lime, and fly ash with a particle size of 1000-1500 mesh after crushing", and the particle size of 1000-1500 mesh is equivalent to 0.012-0.009 mm. The production cost of this kind of particle fineness is very high, and it cannot be applied to the actual production of the building materials industry
