Abstract
An aerocrete for wall is prepared from sand, calcium lime, cement, gypsum and aluminium powder through proportional mixing. Said sand contains quartz which greater than 55%, magnesium oxide less than 5% and clay less than 8%.
Description
Technical field
The present invention relates to material of construction prescription field, specifically a kind of aerated concrete walling material that utilizes sand to make.
Background technology
We know, at present, exist two big problems to be badly in need of solving at China's building material industry: the one, the annual construction of China's building field needs a large amount of materials for walls, the present clay brick of still firing based on clay, fire these clay bricks and taken a large amount of soils every year, caused the loss of land resources.The 2nd,, along with China's high-rise especially construction of high-rise frame building, the materials for wall that needs a large amount of light-weight and higher-strength to require.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome above-mentioned the deficiencies in the prior art, to provide a kind of production cost low, energy-conserving and environment-protective, can making full use of the light wall material of river sand or extra large sand.
The technical scheme that the present invention solves the problems of the technologies described above employing is: the aerating concrete material that utilizes sand to make, adopting sand, unslaked lime, cement, gypsum, aluminium powder is that feedstock production forms, its technical characterictic is that the weight of raw material consists of and contains: husky 55～65%, unslaked lime 10～30%, cement is 5～20%, gypsum 1～8%, aluminium powder 0.06～0.1%.
The requirement of the weight of ingredient is in the sand of the present invention: quartzy magnesium oxide is less than 5% greater than 55%, and clay is less than 8%.
Its production cost of the aerated concrete walling material that the present invention produced is low, intensity is high, thermal and insulating performance good, can utilize river sand or extra large sand fully, saves a large amount of soils.
Embodiment
The invention will be further described below in conjunction with embodiment:
Embodiment 1: must be greater than 55% with quartz content, magnesium oxide must be less than 5%, clay must be less than 8%, sulphur trioxide must be 200 orders～300 orders through ball mill grinding to fineness less than 2% river sand (or extra large sand), 300 kilograms of 550 kilograms in river sand after will grinding again and unslaked limes, the cement double centner, phosphogypsum adds water for 50 kilograms makes ratio of water to material reach 60%～65%, after the mixing, be heated to 30 ℃～40 ℃ and add 0.55 kilogram of aluminium powder whipping agent again, stirring cast rested 1.5～3 hours after 8～15 minutes, the temperature of resting is controlled at 40 ℃～50 ℃, again base substrate is cut, the cutting cycle is 5～10 minutes, steaming needs when pressing at first autoclave to be carried out draining, base substrate after will cutting then pushes steam-cured still, after closing still air in the still is found time, its vacuum tightness is reached-0.65Mpa, feed steam again, make temperature in the kettle reach 190 ℃～195 ℃, pressure reaches 1.1Mpa, and pressure is remained on 1.1～1.3Mpa reach 4 hours, in 1～1.5 hour, the still internal pressure is reduced to normal atmosphere at last, realize the steam discharge process, thereby make the aerated concrete building block of finished product.
