COMPRSSIVE STRENGTH EXAMINATION OF USING SEA SAND AS FINE AGGREGATE REPLACEMENT IN EPOXY BLENDED CEMENT CONCRETE

Abstract

Concrete, the most widely used building material consumes large quantities of aggregates for its production. The use of aggregates has generated major environmental issues, necessitating the adoption of an alternate material to satisfy demand. Polymer concrete essentially is used for special applications and their usage is also not uncommon in today’s world. The current study attempts to increase service life of seasand concrete by combining it with epoxy resin. Initially the removal of some minute impurities such as clay, organic matter and other traces were removed by subjecting them to water washing continuously for about three hours. The removal of chloride ions from sea sand indirectly extends the service life of the concrete produced using sea sand in concrete. Some important physical & mechanical1properties of concrete were studied on sea sand concrete containing epoxy resin as cement replacement. The effort include evaluating the qualities of concrete made with sea1sand as a replacement1for natural river sand up to 50 & 12% epoxy1resin as a partial1substitute for cement
