28 days compressive strength ratio is not less than 75%
Conform to the index requirements of "JC477-2005 accelerating agent for concrete"

Function
Sprayed concrete strength loss is small, rebound rate is low, jet thickness is high, it is helpful to improve the quality and durability of sprayed concrete engineering, has obvious technical and economic benefits

Usage and attention
(1) Dosage 3-6%, usually is 5, 6%
(2) In the use of quick setting agent pay attention to the adaption and freshness of the cement, ensure the dosage according to the environment and experience, keep the temperature between 5-35°C
(3) Pay attention to the water cement ratioshould be 0.4-0.45, should not be too large, with no flowing eject, no spot,uniform color is appropriate
(4) When using should strictly note protectionof the labor

Packing and storage
