Attapulgite-shale hollow block

Abstract

The invention discloses an attapulgite-shale hollow block which comprises the ingredients attapulgite clay tailing, shale, coal gangue, volcaniclastic rock mixture, bentonite tailing powder, kieselguhr tailing, cement, polypropylene reticular fiber and polycarboxylic acid high-performance water reducer. The attapulgite-shale hollow block is prepared by evenly stirring the ingredients and conveying into a full-automatic block machine, pressing to obtain a semi-finished hollow block, conventionally maintaining for 28 days and packaging to obtain the finished attapulgite-shale hollow block. The attapulgite-shale hollow block has the characteristics of good strength, no cracks, heat insulation, energy conservation, sound insulation, less than or equal to 20% of water absorption and good anti-freezing performance; by using a mass of waste as ingredients, not only the resource utilization rate is improved to turn the waste into wealth, but also the land occupation is decreased to protect and purify the environment and save the energy; and the attapulgite-shale hollow block is suitable for the wall construction.

Description

Technical field [0001] The invention involves the field of building materials, and it is specific to a hollow block of a bump shale. Background technique [0002] The new wall material mainly refers to building materials produced by non -clay resources such as sand and gravel, shale, industrial solid waste residue, and building residual soil as raw materials.Application and other characteristics, various concrete blocks are widely used in construction engineering, but due to product quality, building structure, construction process and other reasons, the cracked phenomenon of concrete blocks is common.Leakage is considered a common problem for wall engineering. [0003] The shale is a rock formed by the clay squeezed in the crustal movement. It has a page -like or thin -shaped layer. It is easy to crack into fragments with hard objects.After the block shale is crushed, it can be processed into a shale block. [0004] 80 % of my country's mineral resources are common mines, and a ...

Problems solved by technology

[0009] 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.
