Sep 11, 2019· 3.2. Fine aggregate River sand (RS) which is available nearby the institution (Palar River) was used as fine aggregate for the production of coconut shell and conventional control concretes. Specific gravity of river sand was found as 2.65 and falls in the zone II type of fine aggregate as per IS 383:2016 [13]. 3.3. Quarry dust
crushed concrete aggregate (RCCA) and slag aggregate reclaimed from iron production as pavement base materials since the 1980s. Whether constructed of gravel or recycled aggregate, a pavement's base layer func-tions as a stable, permeable foundation, providing support and allowing water to drain away. Through maintenance inspections,
Aggregate, Coarse Aggregate and cement). From the environment point of view, the huge extraction of the aggregate creates depletion and manufacturing of cement causes pollution. This scenario affects the world's ecological balance. As a civil engineer, we have planned to replace the river sand which is widely used in construction by sea shell.
