alkali-aggregate reaction การใช้

Diagnosis and prevention of alkali - aggregate reaction
Contrete - reactivity of a concrete formula with regard to the alkali - aggregate reaction - performance test
Concrete alkali - aggregate reaction can be great damage to the concrete , which is called the cancer of content
The research of this text is about stopping " alkali - aggregate reaction " , reducing concretes exothermic peak , controling the internal concrete adiabatic storage and using the microexpansivity of magnesia to make up the shrinkage production in the later harden
The liquid - gas method is improved based on the above methods , overcoming the defects of gbj82 - 85 . using the liquid - gas method , permeability condition of concrete can be tested and indicated quickly , efficiently , and the influences on concrete of alkali - aggregate reaction , sulfate attack , carbonization , steel rust , freeze and thaw can be inflected indirectly . it is significant on the research and monitor on the durability of concrete
