A comparative study on behavior of different superplasticizers with fly ash added ordinary Portland cement

The paper presents a comparative analysis of incompatibility behavior of different types of superplasti-cizers with cement in concrete. Along with different superplasticizers, fly ash is added as partial replace-ment of cement with constant water/cement ratio 0.40 to prepare M40 grade of concrete. Mechanical and durability properties of concrete are determined. The different types of superplasticizers revealed encour-aging with 20 percent flyash replacement of cement in concrete.
