EXPERIMENTAL STUDY ON CONCRETE USING SEA SAND

2016-9-9 · Abstract: Concrete is the most popular building material in the world. River sand has been the most popular choice for the fine aggregate component of concrete in the past, but overuse of the material has led to environmental concerns, the depleting of securable river sand deposits and a concomitant price increase in the material. Therefore, it is desirable to obtain cheap, environmentally friendly substitutes for river sand that is preferably sea sand. The Land Reclamation and Development Board (Sri Lanka) plans to popularize the use of sea sand as an alternative to river sand. According to the experts in the global construction trade, Sea Sand is being used in the construction industry in the Asian Region and some leading European countries. Civil Engineering Department of University of Moratuwa (Sri Lanka) and the National Building Research Organization [NBRO] (Sri Lanka) have confirmed that the sea sand pumped from a distance of about ten kilometers is very suitable for building construction industry. This study is to experiment the suitability to use beach/sea sand as a substitute for river sand as fine aggregate
