It can condense and harden speedy when being added into concrete, which possess high early and latter strength.
GK-3A is a kind of milled grey powder after the modified of aluminum oxide clinker,soda carbonate and set controlling agent etc. They can condense and harden speedy when being added into concrete, which possess high early and latter strength. At present, it is an ideal spray concrete and mortar flash setting admixture in our country.
1,Use additive dosage is 4-5% of the cement. Initial condense time is 2-4min,ultimate condense time is below 8min.
2,The resistant stress strength of cement slurry 1d with the addition of GK-3A is above 7.0 Mpa,28d resistant stress strength ratio is over 80%.
3,It is well adaptable to various kinds of cement, low rebound ratio.
Applicable key point
1, In order to confirm the best additive dosage, it is suitable to make an applicable test experiment referred to cement and flash setting admixture before using.
2,During the process of construction, the water-cement ratio should be controlled strictly, it will make a negative influence if the ratio is too big.
3,The concrete with added GK-3A due to reinforce the early maintenance, ensure that the water-cement reaction proceed fluently.
4,It is ought to increase some additive dosage if the cement are placed too long and the construction condition is unfavourably.
Package ad storage
1,The GK-3A should be wrapped in liner plastic film woven bags,25kg per sack.
2,It should be taken care well during the transportation and protected from damage and moisture.
3,Our product of GK-3A should be stored in ventilated and dry warehouse, the validity is five months.
