Use of Sea Shells as Aggregate in Concrete

Exertion towards protecting regular coarse aggregate for future era and diminishing sea shell waste beginning from the fisheries business has started studies on plausibility of coordinating this waste in solid generation. This paper shows the outcome on the workability and compressive strength of solid containing different rate of sea shell content as incomplete coarse aggregate substitution. Concrete blends containing 0%, 5%, 10%, 15%, 20%, 25% and 30% sea shell substitution level were thrown before subjected to water curing for 28 days. Workability test and compressive strength test were directed on solid understanding to IS 516 and IS 4926 respectively. Results demonstrate that substitution of proper sea shell content ready to create workable cement with attractive quality. Coordination of 20% sea shell improved the quality of solid making it to be the most astounding when contrasted with whatever other substitution level.
