Description
Technical field
The present invention relates to a kind of non-fired and non-steamed bricks and building block, particularly relate to a kind of light dolomite non-fired and non-steamed bricks and building block that has a water resisting property.
Background technology
For thousands of years, clay brick is the main building building block of China always.Clay brick must could use through oversintering, and in the process of making sintered clay brick, has both damaged large-area arable land, consumes a large amount of energy again, also gives off a large amount of CO simultaneously
2And SO
2Deng gas, aggravation Greenhouse effect and environmental pollution.For saving resource, protect environment, country bans use of solid clay brick in decision big and medium-sized cities at home for a long time; To the end of the year 2010, all cities and towns, the whole nation will be completely forbidden and use solid clay brick.
For protecting farmland, Chinese invention patent application 00110917.0 discloses a kind of making method of colliery wastes brick, and replacing clay with coal gangue is that raw material is made colliery wastes brick, but still needs sintering; Chinese invention patent application 200410065821.X discloses a kind of making method of blocks from flyash by steaming and pressing, and replacing clay with flyash is raw material, makes flyash brick, but need carry out high-pressure steaming and cultivating.These two kinds of products are meeting consume fuel, discharging waste gas in making processes.
For cutting down the consumption of energy, Chinese invention patent application 200910020879.5 discloses a kind of clay baking-free light insulating brick and preparation method thereof, utilize magnesium oxide and magnesium chloride solution binding agent as various clays, after the insulating brick blanks and moulding and conserving, make clay brick, need not sintering can use, but the main raw material of this product still is a clay.This product still can damage the arable land in making processes.
Replace the material of main part of clay with flyash, building waste and nonmetallic waste slag respectively in Chinese invention patent application 99112868.0 (is unburned, the non-evaporating brick and tile building block series product and the technology of base-material with flyash), 02123184.2 (a kind of baking free hollow wall building block made from construction refuse resource products) and 200810047841.2 (utilizing nonmetallic waste slag to produce baking-free building block and preparation method) as building brick, use magnesium oxide and magnesium chloride solution as consolidating material simultaneously, prepare the sintering free construction brick.These patented products had both been protected the arable land, reduced the energy consumption of product again, and solid waste is got utilization.But in the aforementioned patent product; when utilizing magnesium oxide and magnesium chloride solution as consolidating material; all ignored the shortcoming that the reacted hydrated product of magnesium oxide and magnesium chloride solution does not have a water resisting property; other composition in the above-mentioned patented product does not all possess substantial anti-water conservation effect to this hydrated product; thereby limited the range of application of product; and in the life-time service process; because hydrated product is subjected to the erosion of moist atmosphere and rainwater; corrosion products also can cause the product moisture absorption; return halogen and scum; finally cause the product efflorescence; lost strength; lose use value, influenced the work-ing life of buildings.In addition, magnesium oxide source in the above-mentioned patented product concentrates on Liaoning Province's Haicheng City and Dashiqiao City and Laizhou City, Shandong Province of China, obtain by the magnesite calcining, being subjected to the region on the one hand limits, be difficult to apply in China, on the other hand, again mass consumption the magnesite resource of China's preciousness.
Summary of the invention
The object of the present invention is to provide a kind of lightweight, high-strength, water resisting property good, the light dolomite non-fired and non-steamed bricks and the building block of sound insulation, heat insulation, fire-retardant compliance with environmental protection requirements again.
The present invention is implemented by following technical scheme, and a kind of light dolomite non-fired and non-steamed bricks and building block comprise the component of following weight part:
5 parts～40 parts in light dolomite powder, 4 parts～35 parts of blender solution,
5 parts～85 parts in aggregate, 0.01 part～8 parts of anti-water admixtures.
It also includes the raw material of following parts by weight: 1～50 part of industrial residue.
It also includes the raw material of following parts by weight: strengthen 1～30 part of thickening material.
It also includes the raw material of following parts by weight: 0.01～0.5 part of water reducer.
Described light dolomite powder is that rhombspar is through the powdered material that contains activated magnesia and lime carbonate after the calcining.
Described industrial residue is any one or more than one the mixture in flyash, slag, slag, slag, the desulfurated plaster.
Described blender is the mixture of any one or two kinds in magnesium chloride, the sal epsom.
Described blender solution is that degree Beaume is the magnesium chloride solution of 18～35 ° of B é, the mixture of any one or two kinds in the Adlerika that degree Beaume is 20～35 ° of B é.
Described enhancing thickening material is the mixture of any one or two kinds in magnesium oxide, the Magnesium Silicate q-agent.
Described aggregate is any one or more than one the mixture in natural sandstone, artificial graded sand and stone, mill tailings sandstone, clay pottery sand and haydite, shale pottery sand and haydite, flyash ceramic sand and haydite, coal gangue, building waste, sawdust, the agricultural crop straw.
