Innovative Implications of Paddy Straw in Concrete: A Review

Abstract

Rice is a crop that is grown worldwide and is mostly produced in Asian countries such as China, India, Indonesia, Vietnam, and others. For every ton of harvested rice, around 1.5 tons of paddy straw is produced. Paddy straw is available in substantial amounts during the rice harvesting seasons, depending on the region. In place of burning, governments and communities can promote composting, use paddy straw as animal feed, or invest in technology that turn waste straw into goods that are valuable. Buildings with improved energy efficiency, reduced agricultural waste, and alternative building materials can all benefit from the use of paddy straw in construction. However, proper processing and treatment are required to assure structural integrity, fire resistance, and longevity in construction applications. A thorough analysis was carried out to see how paddy straw might be used to address different environmental issues. It addresses a number of issues, including market potential, sustainability, cost-effectiveness, and technological viability. In this type of research, the durability, workability, and compressive strength of the concrete mix are typically evaluated by replacing a portion of the cement with ash derived from paddy straws. Research topics often include the optimal ash concentration, effects on hydration kinetics, and long-term performance of concrete.
