The main objective of the present investigation is to determine how the physical-mechanical properties of a concrete f'c=210 kg/cm2 vary when it is subjected to a temperature of 800°C and then cooled with water and foam in comparison with a control. shows. . The design methodology used was experimental, where 15 cm cylindrical specimens were used through the different corresponding tests to prepare the mixture design. The concrete samples were divided into subgroups (standard samples, burned and water-cooled, burned and foam-cooled) and then analyzed for weight, volume, compressive strength and modulus of elasticity. Finally, after carrying out the tests, analyzing and comparing the data, it was concluded that the concrete f'c=210 kg/cm2 when subjected to a temperature of 800°C and then cooled with water and foam. Compared with a control sample, it presents an alteration in its physical-mechanical properties, the results being different depending on the cooling agent, observing that the most significant variation is when cooled with foam, which indicates that the concrete of a structure that was burned is more unsafe and loses its physical-mechanical properties to a greater extent if the lifeguards made the decision to use the foam. This also helps the lifeguards to be more strict in safety measures if they choose to use the foam in a structure. .
