¡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.

¡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.
