Problems solved by technology

[0004] However, the existing autoclaved aerated concrete slabs still have various problems during use, such as the low strength, low hardness and heavy quality of the autoclaved aerated concrete slabs, especially the heavy weight of the concrete slabs, resulting in The uneven quality of each part of the board will easily cause the overall center of gravity of the building to shift when it is used, which will lead to immeasurable consequences

Abstract

The invention relates to the technical field of building materials, in particular to an autoclaved aerated concrete slab with uniform texture and a processing method of the autoclaved aerated concreteslab. The concrete slab is prepared by mixing and processing 100 to 110 parts of cement with the size of smaller than 0.01 mm, 85 to 110 parts of quick lime, 12 to 16 parts of talcum powder, 450 to 520 parts of fly ash, 6 to 10 parts of gas formingfoaming agent, 95 to 135 parts of expanded perlite micro powder, 35 to 50 parts of silica flour, 15 to 24 parts of fiber micro powder, 10 to 25 parts of graphene, 40 to 57 parts of marble micro powder, 10 to 50 parts of dispersant, 10 to 35 parts of butyl stearate and 85 to 105 parts of modified sawdust with the size of smaller than or equal to 0.01mm. Three continuous steaming modes of normal temperature and constant pressure, constant temperature and normal pressure and constant temperature and constant pressure are selected in the processingprocess of the concrete slab, and further the steaming effect of a blank body is improved; in the steaming process of changing conditions, the inner part of the blank body slowly creeps, diffuses orshrinkages to drive the dispersion of materials, and the quality and texture uniformity of the finished concrete slab are improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an autoclaved aerated concrete plate with uniform texture and a processing method thereof. Background technique [0002] Autoclaved aerated concrete panels are currently the development direction of domestic lightweight wall panel materials, and are widely used in industrial and civil buildings such as concrete and steel structures. It has the advantages of light weight, high strength, high thermal insulation, good sound insulation, convenient construction, and long-lasting fire resistance. The use of autoclaved aerated concrete slabs to replace traditional aerated concrete blocks and cement slag hollow wall panels can not only greatly reduce engineering time, improve engineering installation quality, and reduce construction costs, but also achieve environmental protection, energy conservation, and improvement. The purpose of improving the surface quality of the wall,...
