        ¡¾General Description¡¿

        Accelerating agent(DK-301) is mainly used in concrete constructions,such as the rush repairmen in the constructions

        of water resistance,anti-permeation,stop-leaking It can coagulate concrete fast,improve the early strength largely,

        small deformation of concrete shrinkage small spray anchor springback is also the feature.

        Liquid Type:3.0-6.0

        ¡¾Instructions¡¿

        The suggested maxing rate is 3.0-6.0 in accordance with cement types,the ratio of water cement molecule,

        the injection parts,injection process quality requirements.

        Fresh high grade cement is needed in shotcrete,the shelf life should be better within a month, 14-40¡æ is the

        best temperature for injection,warm keeping measures should be adopted when the temperature is lower than 10 ¡æ.

        Water cement ratio:the cement type fresh degrees influences the coagulating a lot,please avoid using damp

        out of dated cement.The cement performs good in accelerating when the water cement ratio¡Ü0.4,

        it should be added a little more in lower temperature high moisture situation.Water should be deducted for liquid

        products, No Alkali&No Chloride Type should reduce the adding of water in 5-15.

        Few sediment is allowed,stirring it before using.

        ¡¾Package And Storage¡¿

        25KGS or 50 KGS per woven bag with film in it.

        Please store it in dry ventilated place.

        The expiration date is 6 month based on the environment above.
