Designing a concrete mix for some particular aspects of durability is relatively simple if a correct choice of the constitute materials is made. Adopting carefully designed concrete mixtures in the actual construction is no guarantee that the structures will be durable up to its designed life cycle. The first obstacle is non-homogeneity of the concrete in various parts of the structures caused by insufficient or lack of vibration due to carelessness of the workers or improper supervision. This report illustrates how a combination type SCC, made with a Viscosity Modifying Admixtures in an aqueous solution may be utillised efficiently for constructing durable structure with readily available local material and labour and present several international projects where SCC has been used with success.Also this report illustrates the study carried out on determination of suitable methods for assessing SCC at site. This work is based on the method for assessment of key properties of SCC like flow, passing ability, filling ability and segregation resistance. Final aim of this work is to decide and proposed a test method, which gives fast and accurate assessment of fresh SCC properties. A combination of Slump-flow test and L-Box test has been found suitable for workability assessment of SCC at job sites.
