SJK-905 has good dispersibility, excellent dynamic anti-foaming performance, excellent compatibility and miscibility in water reducer (soluble in water and other additives) , and does not affect the strength of concrete, sJK-905 can effectively increase the workability and fluidity of concrete. The recommended use is particularly suitable for polycarboxylate type water reducer: ▪ leveling mortar ▪ Ready mixed concrete ▪ self-compacting concrete ▪ precast concrete components recommended dosage of 0.03% -0.5% additive dosage (supply form) based on the total amount of water reducer. The recommended addition amount is for reference. The optimum addition amount should be determined through a series of experiments. The additive can be directly added into the water reducer or concrete formula. It is suggested that the additive be added before the air-entraining agent is added.
