Popis: Consumption of concrete has grown rapidly over a year, and it is also becoming one of the basic construction materials. Since, it is a composite mixture of the constituents containing cement, fine aggregate, coarse aggregate and water. For manufacturing the concrete the fine aggregate are required more quantity. In general, river sand and M-sand is used as fine aggregate in construction industry. Due to this increase in use of river sand and M-sand the requirement has been increasing massively day by day in building sector. The government also have given some limitation on mining of river sand from the river beds. So now a day the manufactured sand is used as a replacement of river sand as fine aggregate in construction industry. The treatment needed to remove the salt content in sea sand and sea water is difficult on time of treatment and cost. So, the untreated sea sand is used in this test. The work on this study evaluates the different comparisons of mechanical properties of complete M-sand (MS), complete sea sand (SS) and 50% of M-sand with 50% of sea sand (MSSS). Main intention to consider the sea sand based concrete is to preserve the environmental resource in economical and sustainable development in construction and concrete sector. The experimental test results of sea sand based concrete shows adverse increase in strength compared to M-sand based concrete specimens.
