The effect of lack of curing on the compressive strength of concrete

Abstract

In Peru, "self-construction" represents a constant risk due to its numerous deficiencies, one of them being the lack of curing for concrete structures. This situation leads to serious structural risks. Therefore, the objective of this research was to experimentally determine the influence of the lack of curing on the compression resistance using concrete specimens, this was evidenced through compression resistance tests carried out at 3, 7, 14 and 28 days, obtaining resistance results of 281.32 kg/cm2, 300.82 kg/cm2, 324.58 kg/cm2 and 376.44 kg/cm2 respectively in the cured specimens while for the uncured specimens they were 249.15 kg/cm2, 263.34 kg/cm2, 289.22 kg/cm2 and 312.91 kg/cm2 respectively, showing a loss of resistance of 16.9% after 28 days. Concluding that the compressive strength of concrete is significantly higher for those that are in a 100% cured condition compared to those that have not been cured. This is why it is important not to overlook this process, in order to guarantee the obtaining of quality concrete, thus contributing to the advancement of knowledge and best practices in the construction industry.
