Apply polycarboxylic acid high effective water reducing,concrete admixture,it's liquid. Operative Norm The performance follows the JC476<concrete expansion agent> The construction follows GB50119<concrete admixture application technique standard> Characteristics Appearance Liquid PH value 7 9 Solid content ≥20% Fluidity of cement paste(mm) ≥230 Chlorides Content ≤0.05 Performance 1 Lower water 40%,increase the fluidity of the concrete,it is suit for high performance concrete over C80 . 2 With good adaptability, it could increase the strength of the concrete at early and later period, improve the process of constructions, 3 Small damage, almost no damage in 90min, and could improve the transport time of the concrete. 4 Best quantities is 0.8-1.2%, it can adjust under 0.5% if the concrete is under C25; if the high strength concrete mixture, you could increase the quantity, but not over 2.5%. Application 1 Application precast concrete, fresh concrete, steel concrete, premix concrete of various industry and civilian buildings, irrigation works, port, traffic and government and so on . 3 Application ready mixed concrete, pump concrete. 4 Application high strength, high performance on the anti-permeability, hardening accelerator, self-leveling and steel fire and other special concrete. Use Method 1 Add the standard agent into water or concrete agitating machinery, better to prolong the agitating time 30-60s. 2 Advise you to match and test the best proportion of the specific cements in order to get the best effect. Package and Storage 25-200kg/barrel, better to be transported with tanker, the shelf life is half a year. Attentions 1 Refer to the specification of products to match and test the mixed concrete at first, if you change the cement, please test again to make sure the quality of the construction. 2 Control the quantity of materials, water, and mix agent accurately. 3 If the agitating materials are opening aggregate, it should add water first, and then mix the hardening accelerator. 4 Better to take the machine to agitate. If the worker does it, please prolong the agitating time to make sure uniform. 5 Please follow standards to construct and conserve.
