Abstract
The heat insulating light quartzite brick has the material comprising quartzite 58-64 wt%, cement 21-25 wt%, lime 10-14 wt%, gypsum 3-5 wt%, and aluminum powder 0.08 wt%. The production process includes mixing quartzite and water and ball milling; mixing with cement, lime, gypsum and aluminum powder through stirring in some container while heating; molding and natural expanding in a static curing chamber; cutting to form; and final steam curing at 190-196 deg.c and steam pressure of 107.8-127.4 Pa. The product features light weight only one third of clay brick, high compression strength, high freeze resistance, high heat insulating, sound isolating and fireproof performance, no radioactivity, etc. and may be used as bearing wall in multistoried building, and wall in high-rise building in frame structure.
Description
One, technical field:
The present invention relates to a kind of material of construction, particularly disclose a kind of Guartz sand light heat insulation brick, be applied in building wall, have functions such as lightweight, resistance to compression, insulation, antifreeze, environmental protection, fire prevention, sound insulation.
Two, background technology:
Exploitation has the high-quality novel wall material of comprehensive premium properties, is key subjects of 21 century material of construction innovation.The construction material of current Application and Development fails to have both the shortcoming of comprehensive premium properties: the one, and the cement concrete Hollow brick of exploitation, unit weight is big, and heat retaining property is poor, and easy to leak can not be widely used in the construction wall brick; The 2nd, the autoclaved fly ash brick of exploitation, though light weight, frost resistance is poor, and certain radioactivity is arranged; The 3rd, other materials for wall of exploitation is except unit weight is big, and intensity does not reach the resistance to compression standard of national regulation.In a word, existing various novel wall material quality producies do not reach the standard code that national construction industry is used, and can not be widely used in growing construction industry.In the face of greatly developing of Highrise buildings, in the face of state guarantee cultivated land resource, the real situation that limits and forbid the production and the application of clay brick, Application and Development has the wall body brick of comprehensive premium properties, has been the task of top priority of construction industry.
Three, summary of the invention:
The objective of the invention is to overcome the shortcoming of currently available products, a kind of lightweight, resistance to compression, insulation, antifreeze, environmental protection, fire prevention, sound insulation are provided, the exterior wall and the interior wall that both can be used for high-storey building frame structure can be used for the Guartz sand light heat insulation brick of the bearing wall of tier building again.
The present invention is achieved in that a kind of Guartz sand light heat insulation brick, it is characterized in that the recipe ratio (weight ratio %) of its composition material is: quartz sand 58～64, cement 21～25, lime 10～14, gypsum 3～5, aluminium powder 0.08.The manufacturing process of Guartz sand light heat insulation brick, by material mixture ratio each prescription is weighed and openly to deposit, earlier at normal temperatures quartz sand is added water for ball milling, it is fine sand slurry below 200 orders that the mortar that forms is got fineness at the standard sieve sieve, after inserting the container of heating, the fine sand slurry adds cement, lime, gypsum and aluminium powder add water and stir, and heat up, the interior compound of container of will heating then pours into mould and pours into a mould, the compound and the mould that pour into mould are inserted the chamber of resting, naturally the expansion of getting angry under mesophilic condition, the expansible base substrate cutting forming of resting, inserting autoclave carries out maintenance and becomes product, it is characterized in that: the proportioning material adds water and stirs its water, material is than being 0.58～0.63: 1; The temperature of casting mixture is controlled at 40 ℃～50 ℃.Described autoclave carries out maintenance, and its temperature is controlled at 190 ℃～196 ℃, vapor pressure 107.8～127.4Pa.
The remarkable advantage of product of the present invention is: the one, and light weight, unit weight are 1/3rd of clay bricks; The 2nd, the ultimate compression strength height, frost resistance is good, can be used for the bearing wall of tier building, the exterior wall of high-storey building frame structure and interior wall; The 3rd, insulation, sound insulation, fire resistance are good; The 4th, environmental protection is "dead"; The 5th, both protected cultivated land resource, promoted construction quality again, put on market in the Highrise buildings of hospital, dwelling house, office building and use, be subjected to user's consistent favorable comment, supply falls short of demand at last sea-food, and economic results in society are very remarkable; The 6th, quality detects the requirement that reaches and be better than national building trade GB/T11968-1997 standard code through national Notified body.Detected result is as follows:
(1) 600 kilograms/M of volume density
3± 50 kilograms
(2) ultimate compression strength 〉=4.3Mpa (GB 〉=3.5Mpa)
(3) frost resistance, and intensity 〉=3.9Mpa after freezing (GB 〉=2.8Mpa)
(4) thermal conductivity is [W/ (mk)] 0.13
(5) air-borne sound weighted transmission loss RM44dB
(6) internal radiation index 0.08 (GB≤1.0), external radiation exposure index 0.1 (GB≤1.0)
(7) the brick fire endurance that 200mm is thick reaches 8 hours
