Ceniza de bagazo de caña de azúcar como sustituto parcial de cemento Portland en la elaboración de morteros cementicios de edificación

Abstract

Abstract: Research on ecological mortar and its benefits have been carried out more consistently in recent years, the vast areas occupied for the disposal of agricultural residues in industries and the concern about the sudden global climate change, motivate the use of agricultural residues as artificial pozzolans in construction, showing a favorable way to reduce environmental pollution. In the present work, it is developed with the objective of analyzing and experimenting with the partial substitution of sugarcane bagasse ash (SCBA) in Portland cement through two procedures for its activation, the first is alkaline activation, mixing the ashes with sodium hydroxide (Na OH) and with potassium hydroxide (K OH); the second method is by thermal activation at 500 ºC for two hours. To finish, concrete specimens are made with the pozzolanic supplements derived from the SCBA, which are subjected to physical and mechanical tests to evaluate the improvements presented by the new mortar with respect to the common building mortar.
