Waterproof Admixture For Concrete Using Pozzolan Active Material

摘要

The invention as a physical and chemical reaction in the cement hydration process, when using mixing the composition invented to chaired by the fly Ashton (Fly Ash) and silica fume (Silica Fume) artificial pozzolan (Pozzolan) surfactant (活性 劑) in concrete are designed to provide to a specific water shield (軀體 防水 材) for concrete content to promote strength, permeability decreases, and performance concrete (軀體) water conditions of the concrete admixture (混和 劑) such as the absorbent decreases.; The fundamental reason for the waterproof construction in the structures came been surface coated type, such as cement mortar water use aims to and at the same time ensuring the waterproof performance of structures maintain the durability of the structure, but until now for the waterproofing of concrete structures, non-structural (非構造體) conventional cement mortar waterproof material used for but increase the water resistance and the tight the mortar was to promote curing of the cement during the hydration reaction using the calcium chloride based (CaCl ₂ or CaCl ₂ and 6H ₂ O) and salt-based is a factor of lowering performance of the structure because of the reinforced concrete structures promote corrosion and shrinkage in size there is a performance problem ever for use in concrete structures. The present invention can be obtained to prevent the corrosion concerns and reduction in strength of the concrete and to improve water resistance and concrete performance available to the reinforced concrete structure at the same time effective.; The present invention is complete when the waterproof concrete structure which performance is required, the environmental conditions are poor wet condition or to minimize the structure applicable and the working process in the facing in a narrow working space, and the existing derivative waterproof construction concept membrane of ( Membrane) type and without the water directly to the concrete mixed concrete waterproofing because bangsuhwa the entire concrete structure with performance concrete waterproof concrete admixture that reduces the effects of sigongbi much larger than the other and the shortening effect of permanent keeping durability and waterproof process waterproofing there is an advantage.
