Iam SRIDEVI , studying B.Tech fourth year in srinivasa institute of engineering and technology.
We are doing project that SUITABILITY OF SEA SAND AS FINE AGGREGATE IN CONCRETE PRODUCTION.We know that sea sand in concrete not effect on compressive strength(i.e while using sea sand as fine aggregate the compressive strength of cubes is increases than using river sand) the effect of sea sand only on durability and efflorescense.
so please send documentation about our project( not in a clear way but it contain our requirements i.e how the compressive strength will change and what tests are required for cement ,fine aggregate ,coarse aggregate).
NOTE:Here we are using sea sand without tratment,
using M 30 grade concrete
casting beams and cubes for 7,14,28 days tests.
