Uses and Dosages

1. WhenPolycarboxylate Superplasticizer concrete admixture (Powder)is applied in the form of powder, normal dosage ranges from                     0.*5% to 0.6% of the weight of cementitious material in 1m3 of concrete. When applied in the form of liquid by being mixed with and dissolved into water,Polycarboxylate Superplasticizer concrete admixture (Powder)can be changed into liquid of which density varies from *0% to *0%. In order to optimize the dosage, experiments are required before the adoption of it or changing of the cement type.

2. Recommended dosage: 0.2% of the weight of cementitious material in 1m3 of concrete.

3.Polycarboxylate Superplasticizer concrete admixture (Powder)can be added into cement paste together with water or after mixing, while the latter approach is preferred.

4. The quantity of water must be strictly controlled whenPolycarboxylate Superplasticizer concrete admixture (Powder)is applied, since slump loss of concrete is closely related to it.

5.Polycarboxylate Superplasticizer concrete admixture (Powder)is alkalescent, nontoxic, non-corrosive and environmental friendly. If it gets onto skin or in the eyes, please wash it off with clean water at once. If there is skin allergy, please see a doctor.

6. Do not mix it with naphthalene-based admixtures. If other admixtures, such as set retarder or corrosion-inhibiting admixture, are required simultaneously for some special projects, compatibility tests should be conducted beforehand.

7. When applyingPolycarboxylate Superplasticizer concrete admixture (Powder)in steam curing concrete or other special concrete, abundant experiments are highly recommended to make sure it satisfies the expected requirement.

8. WhenPolycarboxylate Superplasticizer concrete admixture (Powder)is used to make concrete at or below C*5, the total cost may be reduced by increasing the quantity of minerals.
