Effect of polycarboxylate superplasticizers on large amounts of fly ash cements

The conclusions confirm that the use of these types of superplasticizers improves cement behavior, increasing fluidity and decreasing the water demand of cement products. LPC is slightly more effective than SPC. With regard to hardened performance, SPC provides cement mortars with a denser structure which leads to higher compressive strengths and lower water absorption capacity than in both mortars containing cement without superplasticizer and the mortar with LPC. The best performance was had with a dose of 0.15% SPC.
