CHEMICAL WEATHERING OF CONCRETE IN SUB- TROPICAL AND TROPICAL REGIONS

Concrete structures in sub-tropical and tropical regions are usually subjected to leaching action of neutral (rain) water in cycle with drying and high temperatures. Considerable volume of research work has been carried out assessing durability of concrete in aggressive environments (acid attack, salt solutions etc.) but long term quality control of concrete durability in tropics is generally badly defined. In order to fill this gap, an accelerated weathering test intended to evaluate durability of concrete under "normal" conditions of exploitation in tropical and sub-tropical regions is proposed, and some of the investigation techniques discussed (A).
