Efecto de la incorporación de ceniza de bagazo de caña en las propiedades mecánicas y las emisiones de dióxido de carbono del hormigón preparado con residuos de vidrio

Abstract

The production of cement depletes natural resources and emits huge amounts of CO₂. Using waste materials as replacement for cement is a practical solution to produce green concrete. Cane bagasse ash (CBA) and waste glass (WG) have great potential as supplementary cementitious materials. This work presents the effect of the incorporation of cane bagasse ash on mechanical properties and CO₂ emissions of concrete prepared waste glass. Different CBA:WG mass ratio 0:1, 1:3, 1:2, 1:1, 2:1, 3:1 and 1:0 (CBA + WG = 20%) as cement replacement were prepared. The slump decreased with an increase of waste glass and sugar cane bagasse. The incorporation of sugarcane bagasse ash and waste glass it is not related with the density of concrete due to similar density between cementitious materials. The relative compressive strength increased with inclusion of CBA, the 3:1 mixture exhibited the highest relative compressive strength. The CO₂ emissions were reduced when WG and CBA were incorporated. The addition of cane bagasse ash to concrete prepared with waste glass may be a potential option to mitigate the impact of residues and to reduce the CO₂ emissions in concrete industry.
