Description
Summary:This present study aims to develop an eco-friendly high performance biocement using rice husk biomass derived nano Si 3 N 4. The main aim of this study was to investigate the significant effect of adding Si 3 N 4 in the Ordinary Portland Cement (OPC) and the role silane treatment on the nano additive’s surface. The Si 3 N 4 was prepared via thermo-chemical process and grounded using silica mortar. The particles were surface treated using 3-Aminopropyltrimethoxysilane prior to cement mortar preparation. The cubes of standard sizes were prepared using 5, 10, 15, 20, 25 and 30 wt. % of silanized Si 3 N 4 and cured at ambient temperature. According to the results the inclusion of silanized Si 3 N 4 of 15 wt. % improved the compression strength up to 62.6 MPa, which is about 15.61% of improvement than as-received CSA3 designation. The water absorption results show lesser water up take % for silane-treated Si 3 N 4 than as-received one. However a highest final setting time of 985 min was observed for silane-treated CSA6 designation, which could improve the workability of the cement. The scanning electron microscope fractograph revealed that the silanized Si 3 N 4 particle dispersed uniformly than as-received particle. These bio ceramic strengthened eco-friendly cement cubes could be used as building material for safe, environmentally benign and economic construction applications.
