The excess demand for natural River sand (NRS) as a construction material is increasing day by day. As a result of demand, there are server environmental impacts such as lowing the water table, damaging the flora and fauna etc. This study is to focus to prevent the environmental impact by developing artificial sand as a replacement for natural river sand (NRS). Development of artificial sand by mixing high volume fly ash, cement, natural river sand, and locally purchased high solid content polycarboxylate ether-based superplasticizer (HS-PCE). All the physical and chemical properties of polycarboxylate fly ash sand (PFS) were observed and satisfied the requirement of the Indian Standard code. As per IS: 383 – 2016 PFS is classified as Zone-I sand and has a specific gravity of 2.59. However, the angle of friction (41o), pH (11.6), and water absorption (3.58%) values were higher as compared to NRS. Soundness and Alkali aggregate test were within the permissible limit as per Indian Standard. The compressive strength of M25 grade concrete incorporating PFS was evaluated against the same for the control mix incorporating NRS. The trial mix with PFS achieved a 28-day compressive strength of 32.7 MPa which was roughly 4% lower than that of the control mix. This research indicates that PFS would be the best replacement for NRS as reduced the environmental impact of sand mining, also the utilization of waste.
