OBJECTIVE Green building ( sustainable building ) refers to a structure and using process that is environmentally responsible and resource- efficient throughout a building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort.

Although new technologies are constantly being developed to complement current practices in creating greener structures, the common objective is that green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by: Efficiently using energy, water, and other resources Protecting occupant health and improving employee productivity Reducing waste, pollution and environmental degradation.

MATERIALS BAGASSE Sugar cane bagasse is a pozzolana that can partially replace clinker in cement production and reduces emissions of CO2 into the atmosphere. Sugar can bagasse is an agro-industrial residue available in several countries, and it was proved by previous comprehensive studies that its use generally improves the behavior of the cementitious construction materials. CRUMB RUBBER It is a fine granular or powdered rubber capable of being used to make a variety of products such as floor tiles and resilient flooring. It is recovered from scrap tires using thermal and/or mechanical processing techniques. Crumb rubber also is derived from the tire retreading process, when worn tire tread is removed during a buffing process before the new tread is affixed.

GGBF OR GROUND GRANULATED BLAST FURNACE SLAG It is a by-product of iron blast furnaces. The slag is ground into granules finer than Portland cement and can be used as an ingredient in concrete. CRUMB RUBBER It is a fine granular or powdered rubber capable of being used to make a variety of products such as floor tiles and resilient flooring. It is recovered from scrap tires using thermal and/or mechanical processing techniques. Crumb rubber also is derived from the tire retreading process, when worn tire tread is removed during a buffing process before the new tread is affixed.

RICE HUSK ASH The ash produced after the husks have been burned, (abbreviated to RHA), is high in silica. A number of possible uses are being investigated for this. These uses include : aggregates and fillers for concrete and board production economical substitute for micro silica / silica fumes absorbents for oils and chemicals as a source of silicon as insulation powder in steel mills as repellents in the form of "vinegar-tar" as a release agent in the ceramics industry as an insulation material for homes and refrigerants

FLY ASH Asphalt concrete is a composite material consisting of an asphalt binder and mineral aggregate. Both Class F and Class C fly ash can typically be used as a mineral filler to fill the voids and provide contact points between larger aggregate particles in asphalt concrete mixes. This application is used in conjunction, or as a replacement for, other binders (such as Portland cement or hydrated lime). RECOVERED MATERIALS It is waste materials and by-products that have been recovered or diverted from solid waste, but do not include materials and by-products generated from, and commonly reused within, an original manufacturing process.

CONCLUSION To have the knowledge of some of the materials used in construction industry. To understand the various techniques practiced in construction industry to minimize pollution. To analyze the cost reduction due to use of these materials in construction industry. To analyze benefits of off-site manufacture including minimizing waste, maximizing recycling (because manufacture is in one location), high quality elements, better OHS management, less noise and dust.
