Abstract

This paper reviews research from 2022 to 2025 focusing on sustainable concrete incorporating rice husk ash (RHA), recycled aggregates, waste rubber, and nanomaterials. The highlights are mechanical strength, durability, life cycle analysis, and environmental influence. Research records that RHA and rubber tyres improve compressive strength by up to 9.5% over the controls, with superior durability to resist chloride and acid aggression. Life cycle analyses report lowered carbon footprints and higher resource efficiency, and statistical and machine learning simulations optimize mix designs.
