Heading: 1.2Superplasticiser and Fly Ash
Regarding the dose of superplasticiser to achieve a particular target slump; does the dose vary significantly depending on the replacement of OPC (Ordinary Portland Cement) with Fly Ash? Does the Superplasticiser only effect the OPC component? If so, should the dose of Superplasticiser be based on the OPC component alone or the total cementitious.


Do you think superplasticizer can take the place of cement? Perhaps I'm not understanding you properly.
