Abstract

In this research, the resistance of the cement-sand 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 ash in 1%, 2.5% and 5%. %. The resistance 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 217.33 kg/cm² at 28 days. While replacing the cement with sugar cane bagasse ash at 1%, 2.5%, 5% by weight, compressive strengths of: 213.40, 167.07 and 131.77 kg/cm² respectively were obtained, determining that its strength decreases in 1.81%, 23.13% and 39.37%. When the cement was replaced by aloe stalk, compressive strengths of: 110.99, 145.10 and 171.07 kg/cm² respectively were obtained, determining that the strength decreases by 48.96%, 33.24% and 21.29%. Finally, when replacing the cement with Sika Type I, compressive strengths of: 184.17, 214.30 and 249.40 kg/cm² respectively were obtained, it was determined that with 5% replacement the resistance is improved by more than 14.76%, the opposite occurs with 1% and 2.5% that decreases in 15.26% and 1.40%. respectively. Therefore, it is concluded that in the investigation the replacement of Sika Type I improves the resistance.
