Abstract

The invention discloses a powder ash air-entrained concrete building block and a preparation method thereof. The powder ash air-entrained concrete building block is prepared by adding water to 100-200kg of cement, 350-380kg of lime, 1350-1550kg of powder ash, 1.4-1.5kg of aluminite powder and 0.195-0.205kg of foam stabilizers. The preparation method comprises the following steps of raw material preparation, metering, stirring, pouring in a mould, standing for procuring, demoulding, swinging to cutting parts for cutting, steaming and curing in a reactor and finished product warehousing. The building block has the advantages of light weight, good heat insulation, machinability, convenient construction, wide source of raw materials, high production efficiency, low production energy consumption and good fire protection and sound insulation, wherein the dry volume density of the building block is 500-700kg / m3 and amounts to one third of a clay brick; as a large quantity of air holes and micro holes are arranged inside the building block, the building block has favorable heat insulation; as coarse aggregates are not used, the building block has favorable machinability, can be sawn, dug,drilled and nailed and bonded by bonding materials, thereby providing beneficial conditions for building construction; and the building block belongs to a green environmental-protection product.

Description

technical field [0001] The invention relates to the technical field of making an autoclaved aerated concrete block, in particular to an autoclaved fly ash aerated concrete block and a preparation method thereof. Background technique [0002] There is an existing Chinese invention patent whose application number is CN200910304521.5 and the title is "A Kind of Phosphorous Slag Autoclaved Aerated Concrete Block and Its Preparation Method", which discloses an autoclaved aerated concrete block and its preparation method, which is It is prepared by adding water to phosphorus slag, silica sand, quicklime, cement, gypsum and aluminum powder. Compared with the prior art, this invention uses the waste slag produced by the production of phosphorus as the main material to provide siliceous components to produce autoclaved aerated concrete blocks, heat preservation, and can produce different levels of autoclaved aerated concrete blocks according to different requirements . While making...
