Associated scholarship(s):17/21563-4 - Pozzolanic behavior and durability of high performance biocements containing bamboo leaf ash, BE.EP.MS


The word sustainability is every day being more widespread in construction, researches are trying to find new materials that would otherwise be discarded in nature incorrectly.In this context, the pozzolanic materials are increasingly being exalted, because most have industrial or agroindustrial origin, being disposed wrongly. Besides its sustainable role, the pozzolanic materials act physically and chemically in cementitious matrices,improving their properties with regard to durability and mechanical strength. This research aims to study high performance new biocement based on bamboo leaf ash(CFB), in order to contribute to new possibilities of alternative materials. By means ofX - Ray Fluorescence, X - Ray Diffraction, Particle Size, Fourier Transform Infrared Spectroscopy, Thermogravimetric Analysis and Scanning Electron Microscopy, the ash will be characterized physically and chemically. The ash reactivity will be studied through Scanning Electron Microscopy at 28 days cured, Fourier Transform Infrared Spectroscopy and Thermogravimetric Analysis applied in lime/CFB and cement/CFBpastes, both at 3, 7, 28 and 90 days cured. The mechanical behavior will be study using mortars with substitution of 0, 5, 10, 15, 20, 25 and 30% by weight of Portland cement,this analyses will be applied after 3, 7, 28 and 90 days cured.
