I-sand: An Environmental Friendly Sand used in Reinforced Cement Concrete Construction 1Shreya Sanjeev Yadav, 2Dr. D.V. Wadkar
Department of Civil Engineering, AISSMS COE PUNE, India ---------------------------------------------------------------------***--------------------------------------------------------------------sand, its influence on the fresh and hardened properties of Abstract - Now a day’s erosion of rivers and considering environmental issues, there is a scarcity of river sand. The demand of natural sand is very high in developing countries to satisfy the rapid infrastructure growth. Hence it is necessary to find alternative to ‘River Sand’. Benefits of using I sand: Cost reduction; social benefits; Mass utilization of waste material is possible in construction by using steel slag as a partial replacement material for fine aggregates in concrete. Waste or discarded materials produced commonly in industries, factories or mechanical plants are increasing daily thereby constituting increased pollution in environment. Global ferrous scrap availability stood at 750 MT in 2017, 630 MT of which was recycled. Even after recycling, around 120 MT (16% of total) scrap disposed in landfill. The scrap is expected to reach about 1 BT in 2030 and 1.3 BT in 2050. Concrete using ISand gives equal or more compressive strength than concrete using River Sand. Therefore to reduce threat to environment as well as society due to rapid extraction of sand from river bed, we can use iron waste as partial replacement to river sand.
concrete, and its potential economic and environmental advantages. By exploring this innovative approach, we contribute to the growing body of knowledge surrounding sustainable construction materials and their role in addressing the challenges of modern construction practices.

1. INTRODUCTION The increasing demand for construction materials, coupled with the depletion of high-quality river sand, has prompted researchers and engineers to explore alternative materials that can effectively replace or supplement traditional aggregates. One such material that has gained attention is iron sand, also known as iron ore sand, due to its unique composition and potential benefits in construction applications.
3.1.2 Fine aggregate The aggregate size is lesser than 4.75 mm is considered as fine aggregate. The sand used for the experimental programmers was locally available sand and conformed to grading zone II as per IS: 383-1970. The specific gravity were found to be 2.645 3.1.3 Coarse Aggregate
Traditionally, river sand has been a key component in concrete production, providing a fine aggregate that contributes to the workability, strength, and durability of the material. However, the extraction of river sand has raised environmental concerns, including ecosystem disruption, habitat destruction, and alteration of river courses. This has led to the need for sustainable alternatives that can maintain or improve the performance of concrete while reducing the ecological impact associated with sand extraction. This paper aims to provide an overview of the current state of research and development regarding the utilization of iron sand as a partial replacement for river sand in concrete production. It will delve into the key characteristics of iron

Coarse aggregates are those which are retained on IS sieve size 4.75 mm. Crushed stone angular shaped of 10 mm and 20 mm size from a local source was used as coarse aggregate. The specific gravity was found to be 2.85 for 20 mm size aggregate and 2.80 for 10 mm aggregate. 3.1.4 Iron waste Iron waste is collected from Shree Sai agencies, Bhosari Pune. Cost = 15 Rs/kg. This waste is generated from automobiles part.
