Description
Technical field
The present invention relates to building material technical field more particularly to a kind of air entrained concrete straw building block and its preparation sides
Method.
Background technology
Air-entrained concrete building block is light porous one kind, insulation, the good New Building Materials of fire protecting performance, is used
The components such as waste and industry byproduct and cement, lime, sandstone, foaming agent etc. mix, and by dispensing, stir, pour, conserve
Etc. technical process be made, have many advantages, such as that environmental protection, sound-absorbing effect are good, gradually substitute traditional solid clay brick and obtain extensive
Application.
In the application process of air-entrained concrete building block, due to the characteristic and part construction factor of material itself, wall is caused
The problems such as cracking after body construction, hollowing, leakage.Since air-entrained concrete building block itself is a kind of high dispersive porous structure
Construction material, porosity reaches 70%~80%, and air hole structure relative distribution is independent, is the small structure of the big mouth of thorax, has and inhale
Water is more, surface watering is not easy to irrigate, absorb water after moisture evaporation is slow and drying shrinkage value is big feature, this results in air entrained concrete
In the construction process, building block directly absorbs moisture from mortar for building block, and the position part dehydration for making mortar be contacted with building block easily goes out
Situations such as bonding force between existing desiccation layering, mortar and building block declines, porous media is uneven, dry on building block section in addition
Dry shrinkage value is big, is also easy to produce shrinkage stress, and then lead to wall crazing.
In the prior art, the Chinese patent that publication No. is CN106242433A discloses a kind of for air-entrained concrete building block
The water conservation anticracking grout on surface, including cement, granular polystyrene, gypsum, powdered whiting, calcium hydroxide, cellulose ether, wooden fibre
Dimension, latex powder and polypropylene fibre, by improving the water-retaining property and cementitiousness of mortar, reaching prevents building block from being made because of water absorption rate height
It is fast at mortar dehydration and crack and the case where strength reduction occurs.But this is just needed using specific mortar and building block coordinative construction,
It makes troubles for construction.
