DEVELOPMENT OF SUSTAINABLE CONCRETE BY USING OF RECYCLED AGGREGATE IN CONCRETE

Abstract

Sustainable Development is the integrated concept of environmental responsibility with enhancing the natural resource utilization for economic growth and increasing wellness of society. Term of Sustainable Construction Technique includes sustainable design implementation, minimizing of virgin resource and promoting recycle or reuse of construction materials, asset efficiency optimization and so on. Concrete production is an energy intensive manufacturing process creating high level of air pollution especially in the expanding trend of world’s population and urbanization. As a part of the industrial society which is moving to sustainable habit, concrete industry is also establishing the sustainability application on its operation activities by improving durability property, adding waste from other industry, for example fly ash or GGBS, in concrete for a better quality and the use of recycledconcrete as coarse and fine aggregate in concrete. The practice should be traded-off between performances and sustainability indicators. This report provides properties of concrete using Recycled Concrete Aggregate from various studies. Then, availability of using those materials in Thai construction aspect has also been mentioned.
