Effect of processed sugar cane bagasse ash on mechanical and fracture properties of blended mortar

摘要

This paper explored the usage of Processed Sugar Cane Bagasse Ash (PSCBA) as various proportions in cement mortar. Partial replacement of Ordinary Portland Cement by PSCBA leads to reduction in greenhouse gas emission, prevention of natural resource utilization and less energy consumption apart from enhanced cement properties. Mechanical and fracture properties of control cement mortar (1:3, 1:4 and 1:5) and PSCBA incorporated cement mortar (1:3, 1:4 and 1:5) with varying amounts of PSCBA have been evaluated. From experimental results, it is observed that mechanical and fracture properties of cement mortar with 10% replacement of OPC by PSCBA shows enhanced properties and they are compared with other mixes. Increase in calcium silicate hydrate, decrease in ettringite and calcium hydroxide have been observed by FESEM and confirmed with XRD studies. Further, it was observed that the RILEM work of fracture with tail correction and boundary effect method resulted in nearly same sizeindependent fracture energy irrespective of the notch to depth ratio of same specimen.
