Abstract
The invention relates to an aerated concrete. Each cubic meter of the concrete contains 300 to 350 kg of a siliceous material, 160 to 180 kg of a calcareous material and 0.3 to 0.5 kg of a foaming agent. The aerated concrete is characterized by further comprising ferroferric oxide and gypsum, wherein ferroferric oxide accounts for 5 to 10% of the total weight of the concrete, and the gypsum accounts for 2 to 3% of the total weight. According to the invention, ferroferric oxide is added into a conventional aerated concrete formula, so an aerated concrete brick prepared from the aerated concrete provided by the invention has effectively improved compressive strength, meets requirements of bearing and is a lightweight and anti-compression brick.
Description
Technical field
The present invention relates to building material technical field, especially a kind of gas concrete.
Background technology
Gas concrete is to be main raw material with siliceous material (sand, flyash and contain silicon tailings etc.) and calcareous material (lime, cement), admixture foaming agent (aluminium powder) is by the light porous silicate product of preparing burden, stirring, building, technological process such as precuring, cutting, steaming pressure, maintenance being made.Because it contains a large amount of even and tiny pores after getting angry, so name gas concrete.Be applicable to the infilled wall of Highrise buildings and the bearing wall of low-rise building.Non-bearing building block production and use are the most extensive, and volume density is generally 500kg/m
3And 600kg/m
3, mainly use infilled wall and partition wall in structure, and do not bear load; The volume density of bearing building block is 700 kg/m
3And 800kg/m
3, after special structure treatment, bear load under construction; The volume density of insulation block is generally 300 kg/m
3With 400 kg/m
3, it is heat insulation to be mainly used in building heat preserving; Roof boarding and wallboard all are the reinforcement aerated concrete panels, according to the purposes difference, and its arrangement of reinforcement difference.
The ultimate compression strength of most of gas concrete is very low, and when especially wall was weighed in conduct, ultimate compression strength not higher position may be brought out quality problems and security incident.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the not high technical problem of aerated concrete compressive strength in the prior art, a kind of gas concrete is provided, Z 250 can strengthen the ultimate compression strength of gas concrete.
The technical solution adopted for the present invention to solve the technical problems is: a kind of gas concrete, contain 300 ~ 350 kilograms of siliceous materials, 160 ~ 180 kilograms of calcareous materials and 0.3 ~ 0.5 kilogram of foaming agent in each cubic meter of concrete, it is characterized in that: also comprise Z 250 and gypsum, described Z 250 accounts for 5 ~ 10% of gross weight, and described gypsum accounts for 2 ~ 3% of gross weight.
Concrete, described siliceous material comprises sandstone, flyash and Calucium Silicate powder, described sandstone account for the siliceous material gross weight 15%, flyash account for the siliceous material gross weight 80%, Calucium Silicate powder accounts for 5% of siliceous material gross weight.Flyash is core material, and accounting is the highest.
Further, described siliceous material also comprises Magnesium Silicate q-agent and/or pure aluminium silicate, and Magnesium Silicate q-agent and/or pure aluminium silicate account for 2% of siliceous material gross weight.
Described calcareous material is cement and lime, and cement accounts for 20% of calcareous material gross weight, and lime accounts for 80% of calcareous material gross weight.Lime also is one of main raw material of producing of gas concrete, and its main effect is to cooperate with cement effective calcium oxide is provided, make it under hydrothermal condition with siliceous material in SiO
2, Al
2O
3Hydrated calcium silicate is produced in effect, and therefore, lime is one of main intensity source of this product.
As preferably, described gypsum is phosphogypsum.Gypsum is the conditioning agent of the process of getting angry in gas concrete, and the regulating effect of gypsum is mainly reflected in to be cleared up and the delaying of slip multiviscosisty speed unslaked lime.
As preferably, described foaming agent is aluminium powder.Must get angry material as foaming agent, make concrete produce pore, could form light porous structure.
The invention has the beneficial effects as follows that gas concrete of the present invention has added Z 250 in existing gas concrete prescription, can effectively improve the ultimate compression strength that gas concrete is laid bricks, the requirement of the load-bearing of satisfying the demand is a kind of light weight and measuring body laying bricks.
Embodiment
A kind of gas concrete of the present invention, contain 300 ~ 350 kilograms of siliceous materials, 160 ~ 180 kilograms of calcareous materials and 0.3 ~ 0.5 kilogram of foaming agent in each cubic meter of concrete, it is characterized in that: also comprise Z 250 and gypsum, described Z 250 accounts for 5 ~ 10% of gross weight, and described gypsum accounts for 2 ~ 3% of gross weight.Z 250 is the critical formulations that strengthens ultimate compression strength, can improve intensity and ultimate compression strength that gas concrete is laid bricks.Ultimate compression strength can improve 50 ~ 80% than the ultimate compression strength of laying bricks that does not add Z 250.
Concrete, described siliceous material comprises sandstone, flyash and Calucium Silicate powder, described sandstone account for the siliceous material gross weight 15%, flyash account for the siliceous material gross weight 80%, Calucium Silicate powder accounts for 5% of siliceous material gross weight.Flyash is core material, and accounting is the highest.
Further, described siliceous material also comprises Magnesium Silicate q-agent and/or pure aluminium silicate, and Magnesium Silicate q-agent and/or pure aluminium silicate account for 2% of siliceous material gross weight.

2, Al
2O
3Hydrated calcium silicate is produced in effect, and therefore, lime is one of main intensity source of this product.
As preferably, described gypsum is phosphogypsum.Gypsum is the conditioning agent of the process of getting angry in gas concrete, and the regulating effect of gypsum is mainly reflected in to be cleared up and the delaying of slip multiviscosisty speed unslaked lime.
