Abstract

The invention discloses a novel energy-saving autoclaved fly ash hollow wall material, which belongs to the field of building wall materials. It is prepared from the following raw materials in parts by weight: 55-75 parts of dry fly ash, 10-20 parts of carbide slag, 1-2 parts of gypsum, 5-25 parts of aggregate, and 0.5-1 part of sodium metasilicate. It is a cuboid, with blind holes distributed on the front of the cuboid, which communicate with the bottom surface; two of the sides have masonry positioning mortises, and the middle parts of the two sides are groove-type grip holes, and the ribs are set in the groove-type grip. In the middle of the hole, divide the grip hole into upper and lower two. The hollow wall material of the present invention has high compressive strength, large porosity (above 45%), small drying shrinkage, light density, small size deviation, high construction efficiency, excellent thermal insulation and other properties, and can greatly reduce The energy consumption of buildings is much better than traditional wall materials.

Description

technical field [0001] The invention relates to the field of building wall materials, in particular to a light-weight, heat-preserving, heat-insulating and energy-saving building wall material. Background technique [0002] In my country, fly ash bricks have been produced for many years, and the steam curing process has been used to produce fly ash bricks for more than 40 years. Fly ash bricks can replace clay bricks as a load-bearing wall material for industrial and civil buildings, which can save clay consumption, thereby avoiding the reduction of cultivated land and vegetation damage, and can effectively treat power plant waste fly ash. At present, due to changes in building structures and types in my country, enterprises that originally produced autoclaved fly ash bricks are facing the problem of market shrinkage, transformation and upgrading. As the load-bearing material of the inner wall of the building, under the premise of ensuring the strength, new wall materials w...
