Technical field
The present invention relates to a kind of incorporation basalt fibre regeneration concrete wall and apply method, belong to building disaster prevention with it is green
Color technical field of buildings.
Background technique
Since 21st century, social economy's high speed development in the world, urban construction and Development of China's Urbanization
Constantly accelerate, a large amount of industrial civil buildings are rised sheer from level ground with speed as emerging rapidly in large numbersBamboo shoots after a spring rain, thus society enters what new and old building substituted
Peak period.However, the flood tide building waste that a large amount of old buildings generate after removing causes extremely serious destruction to environment, build
Building refuse handling and recycling as the hot spot of society urgently to be resolved.
To promote the sustainable development of construction refuse resource and building trade, response country to promote number of " green building "
It calls together, solve the problems, such as that the raw material such as natural sand stone because serious deficient caused by exhaustive exploitation, regenerate the research work of coagulation material
It comes into being, and made breakthrough progress, regeneration concrete is widely used in various structural elements.But it can't be ignored
It is that regeneration concrete has the weakness such as the low flexural strength of low tensile strength since own material limits to.Based on this, the present invention is mentioned
A kind of incorporation basalt fibre regeneration concrete wall and way are gone out.
Basalt fibre is a kind of novel inorganic environment-friendly and green high performance fibre material, and regeneration is mixed after basalt fibre is added
Solidifying soil material tensile strength flexural strength significantly improves, and mechanical property is significantly promoted.On the other hand, basalt fibre is not only strong
Degree is high, but also has a variety of excellent properties such as electrical isolation, corrosion-resistant, high temperature resistant.The incorporation of basalt fibre effectively promotes wall
The fire resistance of body has outstanding contributions in terms of building fire protection.

Native blanking point dispersed placement, pays attention to placement layer by layer and vibrates, and every layer pours height no more than 500mm；
Step 6: carrying out wet curing in 10h after the completion of the concreting of regeneration concrete wall, curing time 7d is protected
Card concrete is in moisture state；Demoulding is carried out when concrete strength reaches 1.2MPa；Metope and corner are modified after demoulding.
