Attapulgite-shale pulverized coal ash hollow block

Abstract

The invention discloses an attapulgite-shale pulverized coal ash hollow block which comprises the ingredients attapulgite clay tailing, shale, pulverized coal ash, volcaniclastic rock mixture, bentonite tailing powder, kieselguhr tailing, cement, polypropylene reticular fiber and polycarboxylic acid high-performance water reducer. The attapulgite-shale construction waste 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 pulverized coal ash hollow block. The attapulgite-shale pulverized coal ash 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 pulverized coal ash hollow block is suitable for the wall construction.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an attapulgite shale fly ash 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 into pieces w...

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.
