Currently, the construction industry plays an important role in the growth of society, being responsible for the economic development of the population with the execution of infrastructure whether housing, transportation, agriculture, sanitation, etc .; this is why this thesis proposes different alternatives for curing concrete, with different chemical healers, in order to improve the properties of concrete in hardened state (resistance to compression and permeability). For the elaboration of the thesis, Pacasmayo Type I cement was used, a coarse aggregate of maximum nominal size ½ “, a fine aggregate with a fineness modulus of 2.6 that is in the permitted range according to (NTP 400.012, 2013), using the method (ACI 211, 2001) to make a concrete of f'c = 210kg / cm2 with a 4 “Slump. A total of 76 cylindrical specimens of 15cm in diameter and 30cm in height were made, so it was taken into account to use different curators, such as the Super Curator Chema, Sika Antisol S and Per Kurevista, all of them were cured by sprinkling, while others, the curing was carried out by immersion in water. In the compression resistance test, 64 test tubes were used, which were tested at 3; 7 and 28 days of curing, obtaining as a result that the witnesses cured by immersion in water are 301kg / cm2, which represents a standard value, while the Super Curator Chema, obtained 270kg / cm2, 90% of the concrete pattern, Per Kurevista, with 266kg / cm2, equivalent to 88% of the concrete pattern and Sika Antisol S with 280kg / cm2, which is 93% of the concrete pattern. For the capillary permeability test, 12 cylindrical specimens were used after 28 days of curing, resulting in that the cylindrical witnesses that were immersed in water, have less capillary absorption, because during their curing they were totally immersed in the water, unlike of the chemical healers, since its application is by spray and its curing is only to the surface of the cylindrical witnesses. In terms of costs, a detailed analysis was carried out of the chemical healers and the curing by immersion in water, obtaining that the lowest cost is Per Kurevista; but because, in the compression test, it showed the lowest result with 88% of the concrete pattern; it was decided to choose the Sika Antisol S healer as the most economical and effective against compression resistance test with 93% of the concrete pattern.
