Avaliação da influência dos diferentes tipos de cura na resistência à compressão de concretos produzidos com diferentes tipos de cimento

Abstract

The purpose of this article was to evaluate the axial compressive strength of concretes produced with different types of cement subjected to different types of cure. Initially a dosage was defined with the use of three types of cements, CP II F 40, CP IV and CPV, molded and submitted to four different types of cure; submerged, chemical, in the ambient air and with autoclave. For each method, ages of 1,3,7 and 28 days were adopted, following the gain or not of resistance over time. Thus, it was verified that the submerged curing presented greater resistance gain for all the cements used in all curing ages. However, it was reported that CP V obtained greater resistance at all ages for all types of cure when compared to the other cements used.
