Abstract This research examined the minimum curing period of concrete in hot weather concreting. As a result of the experiment using the full scale concrete wall specimens(experiment I), it was clarified that ...the surface part of the concrete walls removed frameworks in the early age less than 3 days deteriorated apparently, although the significant difference in measured values of concrete strength did not be observed according to the difference of its curing period. The reason that the effect of the curing period on compressive strength were not obvious as compared with that on the porosity of cement hydrates and the carbonation were explained on the relation between the strength and the thickness of the deteriorated layer(experiment II).show more
