Attapulgite-shale-river silt-ceramsite hollow building block

Abstract

The invention discloses an attapulgite-shale-river silt-ceramsite hollow building block. The attapulgite-shale-river silt-ceramsite hollow building block is technically characterized in that the ingredients of the attapulgite-shale-river silt-ceramsite hollow building block include attapulgite clay tailings, shale, spherical attapulgite-river silt ceramsite, pyroclastic rock mixture, bentonite tailings powder, cement, polypropylene reticular fiber and polycarboxylic acid high-performance water reducing agent. The ingredients are stirred to be uniform and then are pressed into the semi-finished product of the hollow building block, and after being conventionally maintained for 28 days, the semi-finished product is packaged into the finished product of the attapulgite-shale-river silt-ceramsite hollow building block. The attapulgite-shale-river silt-ceramsite hollow building block has the characteristics of good strength, no crack, thermal insulation, energy conservation, good sound-insulation and heat-insulation properties, water absorption rate being not more than 20%, and good antifreezing performance; a great quantity of wastes are adopted in the ingredients of the building block, thereby favorably improving resource utilization rate, changing waste into wealth, reducing land occupation, protecting and purifying environment, and saving energy; and the attapulgite-shale-river silt-ceramsite hollow building block is suitable for wall construction.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an attapulgite shale river bottom 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 brea...

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.
