How To Use

1.This product Polycarboxylate Superplasticizer PCE Liquid is a colorless or light yellow liquid. recommended dosage as below:generally , 5%-30% of mother liquor is used to mix other small materials to make water-reducing agent.The dosage of water-reducing agent is generally 1% ~ 3% of the total weight of cementitious materials.

2.Before use of this product or changing the type and batch of cement and gravel, it is necessary to carry out adaptability test with cement and gravel. According to the test, formulate the proportion of water reducing agent.

3.This product Polycarboxylate Superplasticizer PCE liquid can be used alone or combined with slow-release mother liquor to reduce concrete slump loss; Or compound with functional auxilaries to get admixtures with retarder/early strength/antifreeze/pumping functions. The application method and conditions should be determined by testing and compounding technology.

4.This product Polycarboxylate Superplaticizer can be used together with other kinds of admixtures such as early strength agent, air entraining agent, retarder, etc., and should be tested before use. Do not mix with naphthalene series water reducer.

5.Concrete cement and mix ratio should be determined by test, When using, mixed and measured water should be added or added to the concrete mixer at the same time. Before using, the mixing test should be carried out to ensure the quality of the concrete.

6.When there are active admixtures such as fly ash and slag in the ratio of concrete, the amount of water-reducing agent should be calculated as the total amount of cementitious materials.
