Abstract
This projects aims at bringing out the role of Viscosity Modifying Agents and how various VMAs affect the properties of self-compacting concrete differently. The main reason behind this study is to find out which VMA is best suited for the particular cement being used in the manufacture of SCC. In this project, two different viscosity modifying agents are used namely Glenium Stream 2 and Rheomac VMA 358. The quantity of the VMA added is the same for both the test conditions and their properties are checked as per standard SCC tests. Comparative study is done between the test mixes and the results are drawn to bring out the more optimum VMA for the cement used. Only fresh concrete tests are done so as to attain the workability related results. There was variation in the fluidity based on the dosage of the VMA provided
