Resumen

In this res earch, the res is tance of the cements and mortar (C:A) in a 1:3 proportion is analyzed when replacing the cement by weight with Sika Type I, penca aloe and sugar cane bagasse as h in 1%, 2.5% and 5%. %. The res is tance of the mortar was determined at 1, 7, 14, 21 and 28 days of curing, determining that, for each type of additive replaced by the weight of the cement, the results have varied markedly. The compressive strength of the standard mortar is kg/cm2 at 28 days. While replacing the cement with sugar cane bagasse as hat 1%, 2.5%, 5% by weight, compressive strengths of: 213.40, 167.07 and 131.77 kg/cm2 res pectively were obtained, determining that its strength decreases in 1.81%, 23.13% and 39.37%. When the cement was replaced by aloe stalk, compres sive strengths of: 110.99, 145.10 and 171.07 kg/cm2 res pectively were obtained, determining that the strength decreases by 48.96%, 33.24% and 21.29%. Finally, when replacing the cement with Sika Type I, compressives trengths of: 184.17, 214.30 and 249.40 kg/cm2 res pectively were obtained, it was determined that with 5% replacement the res is tance is improved by more than 14.76%, the opposite occurs with 1% and 2.5% that de creases in 15.26% and 1.40%. res pectively. Therefore, it is concluded that in the investigation the replacement of Sika Type I improves the res istance.
