Abstract:
Concrete curing is an undisputed accepted practice to obtain the best possible quality material. Keeping the concrete humid during the first weeks allows most of the cement to transform in hydrated products, which give the material its agglutinating power. In some regions around the world, ambient humidity would keep concrete moist naturally, thus not requiring resources to moisten or to seal the surface. The aim of this work was to compare the compressive strength values obtained when concrete is subjected to moist and ambient curing processes during the different seasons of the year, under a hot sub-humid climate. Results showed a meaningless influence of moist curing in the strength at early age, and a moderate influence at medium age. Also, few variations in the results were found throughout the year.
