Abstract – This paper primarily aims to study the
By appropriate addition of different fractions of glass sand, the variation in the properties of concrete can be studied in terms of its compressive strength and workability.
performance of recycled waste glass sand as a partial replacement for fine aggregate in concrete. Fine aggregates are replaced by recycled waste glass sand at varying fractions to check the compressive strength and workability. Replaced mixes are compared with the conventional mix in terms of workability and compressive strength to evaluate the effectiveness. The workability was determined by a slump test on fresh concrete with all the above waste glass sand fractions. Compressive strength at 7-days and 28-days curing was determined for all concrete mixtures. The obtained results were analyzed and compared with that of the conventional concrete mix of M25 grade. From the above analysis, mixing with 50% waste glass sand is considered optimal in terms of compressive strength. Hence this study verifies the potential of recycled waste glass sand as a construction material and thereby leading to a sustainable construction process.
This study entails the performance analysis of concrete containing varying amounts of waste glass sand as a partial replacement for fine aggregates and thereby confirming its potential as an efficient construction material. 1.1. Aim To study the performance of utilizing recycled waste glass sand as a partial replacement for fine aggregates in concrete. 1.2. Scope

2. METHODOLOGY
1.INTRODUCTION
Collection of materials
Concrete is dominant in modern construction procedures due to its versatility, durability and strength. It serves as a foundational material for various structures including buildings, bridges, and infrastructure. Fine aggregates, being an important component of concrete, are mainly natural sand extracted from riverbeds. Since these natural resources are getting depleted day by day due to increased constructional activities, the industry is dealing with a dual challenge of balancing sustainability as well as infrastructural development.

The disposal of glass is a major environmental issue since it is a non-biodegradable material. Around the world, among 200 million tons of solid waste, 7% is contributed by glass. So, to promote a sustainable construction process, natural sand can be replaced by waste glass sand. Utilizing waste glass in concrete not only addresses environmental concerns by recycling glass but can also check its potential to enhance the performance of concrete. This approach reduces the demand for natural sand, mitigating the impact on riverbeds and ecosystems.
