Specifications:
(1) liquid 50% ( could with a solid content of 20%-55%).
(2) With a high slump retention ability, without concrete segregation, with a much smaller slump loss than that of other superplasticizers.
(3) With a good dispersion, an excellent adaptability to different cements, and good water-reducing properties. A high water-reducing ratio up to 40% could be obtained when used in high strength grade concrete.(higher than C50). With a dosage of 0.4%,water reducing rate up to 32%.
(4) Cement paste fluidity ≥250mm (with a dosage of 0.3%).
Uses and Cautions:
(1) A recommended dosage is 0.25%-0.8%. Actual dosages should be determined by mixture design test according to concrete strength grade.
(2) 0ºC-40ºC the shelf life of liquid products is 12 months.
(3) Concrete test must be carried out before utilization.
(4) This product is forbidden to be mixed with naphthalene superplasticizers.
(5) Experiment must be done when it is used together with other admixtures.
