Description

A kind of biology grey matter Self-heat-insulating concrete building block and preparation method thereof
Technical field
The present invention relates to concrete segment technical field, more particularly, to a kind of biological grey matter Self-heat-insulating concrete building block and Preparation method.
Background technology
Concrete segment is the common wall main material of building trade at present, due to intensity height, from heavy and light, is built by laying bricks or stones conveniently, wall Surface evenness is good, high efficient construction, has become the product that national construction sector is recommended first.Since worker is carrying out Mortar can inevitably be fallen into the hole of building block, be resulted in waste of resources when building by laying bricks or stones, and wall lower part because mortar accumulation cause from Increase again, thermal coefficient increases, and thermal conductivity is deteriorated, and sound insulation property reduces.Concrete hollow block filler currently on the market Mostly foam cement and eps foam plate, wherein foam cement cost is excessively high, and it is big that eps foam plate produces and processes difficulty.Another party Face, in China Tibet region, cow dung has history in thousand as the fuel that tea is cooked is burnt, and lives in the vast agriculture of snow-coated plateau Herdsman regards it as best fuel so far.But it is burned after grey matter cow dung ash (cattle manure ash- are hereinafter referred to as For CMA) most emergency burial, resource is not only wasted, but also cause environmental pollution.And with the quick hair of cattle-raising Exhibition, fecal pollution have become a great problem, according to the relevant information, in some places, cow dung has been more than to the pollution of environment The total amount of industrial pollution, some are even as high as 2 times or more.
Invention content
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of new bio grey matter concrete The advantages that heat insulation building block has good heat insulating, and production cost is low, and machinability is strong, to realize the utilization again of resource, Keep building heat preservation performance more preferable.
To achieve the goals above, the technical solution adopted by the present invention is that：
A kind of biology grey matter Self-heat-insulating concrete building block, including common specification concrete small size hollow building block 1, common specification 1 hollow part of concrete small size hollow building block fills mixed foaming filler 2.
Common 1 size of specification concrete small size hollow building block is 390mm X 190mm X 190mm.
A kind of preparation method of biology grey matter Self-heat-insulating concrete building block, step are：
Step 1：According to mass ratio it is (2.5-3.0) by cement and CMA：(6.5-7.0) is mixed, and obtains mixture, water Mud uses 42.5R Portland cements；
Step 2：Add water in the mixture obtained to step 1, the mass ratio of mixture and water is 1：(0.18- 0.2) CMA cement mortars, are obtained；
Step 3：The fine uniform foams of 0.8-1.2mm are made in foaming agent water solution, foam and CMA cement mortars are fully mixed The hollow part of concrete small size hollow building block 1 is injected after conjunction with pouring pump；The mass ratio of foam and CMA cement mortars：(0.032- 0.034)：1；
Step 4：1 constant temperature and humidity of concrete small size hollow building block after foam and CMA cement mortars are sufficiently mixed will be injected Condition conserves 2~3 days, and natural curing 7~10 days again after demoulding obtain biological grey matter Self-heat-insulating concrete building block.
The condition of the constant temperature and humidity is：It is constant at 20 DEG C ± 2 DEG C to conserve indoor temperature, humidity be maintained at 95%RH with On.
The foaming agent water solution is mixed using animal foaming agent with water, and volumetric concentration is percent 10.
Beneficial effects of the present invention are：
The present invention is used as building-block filler using CMA and cement admixture foaming, prevents construction spillage first, keeps away Exempt to cause the heat-proof quality of building block to be deteriorated, conduct oneself with dignity increase and the wasting of resources since the mortar fallen into is excessive；Next is reduced Thermal coefficient so that the self-insurance warm nature of building block gets a promotion；Furthermore while improving heat-insulating property, excessive increase is had no Building Integral Loading；Finally, recycling CMA not only economized on resources, but also avoided polluting.
