dc.description.abstractEarly thermal cracking in concrete water retaining structures mainly depends on temperature fall between hydration peak and ambient temperature (Tr). Since values of Ti given in BS 8007,which is the code of Practice used in Sri Lanka for design of water retaining structures, are not valid for conditions in Sri Lanka, experimental investigations were carried out to obtain appropriate values of Ti for local conditions. Temperature rise in concrete wall panels of 300mm, 500mm and 1000mm thick was monitored using thermocouples across the depth of each panel. A concrete mix with a cement content of 400 kg/m3 was used. It was found that the Ti values for local cements with 12 mm plywood formwork are very much smaller than corresponding values given in BS 8007. Based on the test results Ti values were proposed for cement content of 400 kg/ m3 and 12mm plywood formwork.
