XF-I Early Strength Agent concrete additive

XF-I early strength agent can be applied grout concrete construction,precast parts, road, bridge, culvert Operative Norm The performance follows the GB8076<concrete admixture> The construction follows GB<concrete admixture application standard> Characteristics Appearance power Solid content % ≥90 Fineness(0.315mmsieve residue)% ≤10 Performance 1 Significantly effect, the strength of pressure under the same situation is 1D≥125%-140% 3D≥120%-130% 7D≥110% ,and it would increase in the later period ,the strength of 28D is higher than standard concrete obviously. 2 Shorten the construction cycle, increase the rate of model turnover 30-50% 3 Improve the workability of concrete, increase the performance of anti-permeability and anti-freezing. 4 Non-toxic ,incombustible, no-corrosion to the steel and other substances, not including chloride . Use Method 1 The required quantity is 1-3% of the cements; the usual quantity is 2%. 2 Mix methods: Mix together, mixes later and mixes in several times. Usually mix together, that is mix the product and cements, then mix with Aggregate then add water to agitate, the time of agitating should prolong 30-60s. Package and Store 1 The standard of package is 50kg/bag 2 Store at the dry and Ventilate place, prevent to be wet. 3 Best using in a year after producing, it should match and test if it is over one year. Attentions 1 Refer from 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, mix agent accurately. 3 If the agitating materials are porous bone ,it should add water first ,then mix the early strength agent. 4 Better to take the machine to agitate. If the worker does it, please prolong the agitating time to make sure uniform. 5 As to the methods to agitate, transport, it is the same with ordinary concrete. 6 Please follow referent standards to conserve.
