✦ Synopsis

Understanding of environmental effects on concrete behaviour is still far from complete; building codes and specifications that give design procedures are continually changing to reflect latest knowledge. As an addition to the unsettled topic a preliminary investigation on some concrete properties has been carried out. It has been observed that, even though the required concrete strength in hot-humid climate is obtained, the elastic modulus could be reduced by a small extent. At the same time the outdoor shrinkage could be found to be much less than the controlled indoor shrinkage. On the whole, the prevailing parameters of hot-humid climate are experienced to have considerable effects on outdoor concrete properties, but the experimental data reiterate that the long-term effects might not be adverse as those usually reported in other climates.
