workability, microstructure and compressive strength of self compacting geopolymer concrete (SCGC). SCGC is an improved way of concreting execution that does not require compaction and is made by complete elimination of ordinary Portland cement content. The parameters studied were superplasticizer (SP) dosage and molarity of NaOH solution.

Difference Between Plasticizer and Superplasticizer

Plasticizers and superplasticizer are added to concrete mixtures in order to reduce the water: cement ratio, thereby, reduces the water requirement in the production of concrete. The main difference between plasticizers and superplasticizers is that plasticizers can reduce the need for water by 5-15% whereas superplasticizers can reduce the need for water by 30%.
