ABSTRACT
One of the construction materials that tend to show significant price increases due to variable agents is cement, which is an essential construction material in the region. This article studies the feasibility of a proposal to replace the percentage of cementitious material in hydraulic cement mortars with one of lower cost and environmental impact, bamboo leaf ash (CHB, for its initials in Spanish), which various authors have indicated that it has considerably pozzolanic properties. The complete procedure for obtaining this supplementary material is presented, ranging from the collection of the bamboo leaves themselves to their drying, crushing and incineration to obtain the ashes. The study aims to justify the use of bamboo leaf ash in mortars through the analysis of compressive strength test results to evaluate its resistance. During this study, promising results were obtained in the compressive strength tests of mortars that incorporate CHB, both at early testing ages (24 hours, 3 and 7 days), and at advanced testing ages (28 and 56 days), for which the CHB mortars compressive strengths were superior or very similar compared with the control mortars’ compressive strengths, having these results important implications in the development of new sustainable materials with future potential to be implemented in the concrete industry.
