REDUCING ENVIRONMENTAL IMPACT: PERFORMANCE EVALUATION OF CONCRETE USING RECYCLED CONCRETE AGGREGATES

Abstract

Sustainable materials are becoming increasingly popular as a result of the need for the building sector to minimize its negative environmental effects. Recycled Concrete Aggregates (RCA), produced by repurposing demolished concrete buildings, are a viable option. In order to determine the mechanical characteristics, longevity, and overall environmental impact of concrete using RCA, this study undertakes an extensive evaluation of the material. This study examines the literature that already exists using a deductive method of inquiry and an interpretive approach, as well as methods for gathering secondary data. It is thoroughly assessed how well RCA-based concrete performs in terms of its compressive property, tensile toughness, modulus of elastic property, and flexural strength. Additionally, a thorough analysis is done of durability factors such as nitrate resistance, ionized chloride penetration, as well as freezing-thawing resistance. A life cycle examination is also carried out to calculate the environmental advantages of RCA adoption. Important insights regarding the ecological benefits of using RCA-based material are provided by the assessment of parameters such as emissions of carbon dioxide, usage of energy, as well as resource use. The findings provide insightful technical information about whether RCA can be successfully incorporated into construction procedures. This research contributes to our knowledge of the environmental effects and structural performance of RCA-based concrete, laying the groundwork for sustainable building practices. The results also point to areas where RCA integration throughout the construction sector might be improved, standardized, and further innovated.
