Currently, due to its versatility and low production cost, concrete is the most used construction material in the world. On the first days after being launched, concrete goes through a period called curing. This curing is directly related to the conditions to which the material is submitted, in particular, temperature and humidity. In this work, the effect of temperatures of 5ºC, 23ºC and 30ºC on the curing of specimens subject to the same humidity conditions was analyzed. Nine groups were molded, each one containing 6 specimens, which were divided in the previously described conditions for periods of 3, 7, 14 and 28 days. At 28 days, all groups were tested and the influence of temperature on the results of resistance to compression was analyzed. The results showed that the greatest losses of resistance values occur among the groups cured at a temperature of 5ºC, although curing at 30ºC also results in a decrease in resistance values. |
