Durability Properties of Self Compacting Concrete by using M-Sand as Fine Aggregate

Self-compacting concrete is also called as self consolidated concrete which does not require vibration for placing and compaction. In the present trend scarcity of natural sand become a huge problem to construction industry, inorder to reduce this problem alternatives are used, one of the alternative material is Manufactured sand. Manufactured sand is produced from hard granite stone by crushing. There are two reasons to M-sand i.e, availability & transportation. An attempt was made to evaluate the workability and strength characteristics & durability properties of self compacting concrete with river sand and manufactured sand as fine aggregates. For each replacement level, constant workability was maintained by varying the dosage of superplasticizer. Sulphate attack and chloride attack of the specimens were determined. Different proportions of solution are used for durability study.
