Description

Execute standard The performance follow the JC**6<concrete expansion agent> The construction follow GB****9<concrete admixture application technique standard> Homogeneous : Appearancepowder Solid container≥*7% fineness0.*8≤*0% Performance 1)Improve the performance of anti-crack and anti-permeability , and also possess the function of compensation and contract. 2)The expansion rate of concrete is 0.***0.*4%, it could construct prestressed 0.**0.7Mpa, anti-permeability S*0. 3)Contain tiny quantity of alkali, lower the harmness that expansion agent to the concrete alkali aggregate. 4)Non-toxic , fireproof, no corrosion to the steel and other substances, not including chloride Usage: 1 The required quantity is ***2% by weight of the cement. 2 Mix methods: Usually mix together, that is mix the product and cements, sand, stone, water to ***** time of agitating should prolong ****0s. Precaution: 1 Refer to the specification of products to match and test the mixed concrete at first using, if you change the cement type , please test again to make sure the quality of the construction. 2 Control the quantity of materials , water , mix agent accurately. 3 If the agitating materials are porous bone , it should add water first , then mix the expansion agent. 4 Better to take the machinery to agitate .If the worker do it , please prolong the agitating time to make sure uniform. 5 As the methods to agitate, transport, grout are the same with ordinary concrete. 6 Please follow referent standards to conserve
