Three Formulation Guidances of Hybrid Polycarboxylate (PCE) type superplasticizers(Sps)
(1)PCE superplasticizer can not be combined with sulfamate water reducing agent, naphthalene based water reducer, melamine water reducing agent, wood calcium water reducing agent and so on. It can be formulated with aliphatic high-efficiency, wood sodium, wood magnesium common water reducing agent in the appropriate proportion range. (2)Any powdered component should not be dissolved directly into the PCE liquid, but should be made into an aqueous solution and mixed with the PCE liquid. (3)PH value of PCE solution often makes a difference in the quality of the compounded, In principle, when pce solution PH =7, should select components that are stable in alkaline environments such as baking soda, sodium citrate, dextrin, sodium nitrite, etc. PH<7 Choose Materials that are unstable in alkaline environments such as citric acid, phosphoric acid and sodium pyrophosphate. Materials, such as sodium gluconate, sodium nitrate, methanol, and triethanolamine, can be compounded in both acid and alkali PCE
