In the last decades, many works are going in direction of valorization vegetable biomass. The aim present work is to determine dynamic modulus elasticity a cementitious matrix composite with rice husk ash pozzolan reinforced sugarcane bagasse. To do this, we formulated mortars which varied volume fraction bagasse and kept 10% as cement replacement. fractions 0%, 3%, 6% yielded denoted RHA10, R1...
Various types of additives have been diachronically used in historic mortars, whereas their use lime-based grouts, for the restoration structures, is rather limited. In this study, an effort was made to investigate performance glass consisting lime and natural pozzolan. The concerned fibers (3 6 mm length), beads bubbles, added a proportion 0.3–3% w/w binders. Five grout compositions were manuf...
In this study, a protocol for synthesising β-C2S using K2SO4 as dopant has been reported. Quantitative X-Ray diffraction was used to characterise synthesised samples. It observed that it is possible synthesise with high purity (>96 wt%) and limit the formation of free lime below 0.5 wt% protocol. Unreactive γ-C2S main secondary phase present in sintered Isothermal calorimetry studies were condu...
