Two types of liquid polycarboxylate super plasticizer water reducing admixtures1. Polycarboxylate superplasticizer water reducing admixture (CL-WR)
2. Slow release polycarboxylate superplasticizer slump retention water reducing agent (CL-SR)
Advantages:
New formula,fully reaction, pure appearance
1. High water reduction
2. Low dosage, and so to save cost in comparison with other water reducers at equal performance
3. To maintain slump perfectly
4. To enable a much better flowability of the mixture
5. To improve the strength and durability of the concrete drastically
6. To save cement at equal strength and durability
7. Eco-friendly since no formaldehyde

CL-SR-50 slow release slump retention polycarboxylate superplasticizer water concrete admixture
Note:
(1)Slump retention type (CL-SR-50) using is suitable for compounding with high water redcuing type(CL-WR-50). According to the concrete materials to determine the final mixing ratio. The product adapts to all kinds of concrete/cement.
(2)CL-SR-50 is slow release slump retention type water reducer. it will be effected in the period of 30min to 180min.
(3)concrete mortar 180min no slump. CL-SR-50 has super slump retention ability. it should be mixed with CL-WR-50 .
Specifications:
(1) polycarboxylate superplasticizer 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).
(4) Low chloride content, and no corrosion to steel.
(5) 180min Cement paste fluidity ≥260mm (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. After expiration date, concrete test must be carried out to confirm the quality.
(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.
