AN EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES FOR REPLACEMENT OF RIVER SAND WITH SEA SAND AND ROBO-SAND IN CONCRETE

Now a day's urbanization requires lot of ingredients in infrastructure development. Smart cities are always be safe and economical either in construction or living. In view of urbanization concrete is used for all type of constructions. Concrete is having cement, fine aggregate, course aggregate. Sand plays vital role in concrete in all type of constructions. In this study gives the comparative experimental results in compressive and tensile strengths of concrete for M20 grade under curing periods about 7 days, 14days and 28 days replaced fine aggregate with sea sand and robosand. The objective of this paper is to give detailed study whether robo sand and sea sand are advisable to use or not. The removal of salt and impurities from sea sand and river sand is mandatory. Using different proportion of sea sand and robo-sand in the place of river sand has been taken for tests.
