Resumen

The objective of this study was to analyze the physical and mechanical properties of mortars produced by partially replacing water with a homemade waterproofing agent, in proportion of 10% and 20%. Three types of mortar (0%, 10%, and 20%) were prepared and evaluated through tests of water absorption, capillary action, and compressive strength. The results show that the mixtures with 10% and 20% exhibit lower absorption and capillarity values compared to conventional mortar, as well as higher compressive strength values, with the mortar containing 20% reaching a value of 236.36 kg/cm2. Statistical analysis using ANOVA, Levene's test, and Tukey's HSD test confirmed the existence of significant differences among the evaluated groups. However, it is important to note that experimental design involved simultaneous variation in the water-to-cement ratio; therefore, the results should be interpreted as the combined effect of the variables and cannot be attributed exclusively to the waterproofing agent. In conclusion, the mixtures with the highest substitute percentage exhibit favorable behavior in terms of physical-mechanical performance; however, it is recommended that future research maintain a constant water-to-cement ratio and incorporate durability tests to more accurately evaluate the influence of the additive on the mortar.
