Microstructure Analysis Of Cement Mortar On Partial Replacement Of Fine Aggregates By Industrial Wastes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
The industrial wastes due to their high performance when blended with the building materials generated great interest in the field of structural engineering. Many industries are looking for the effective use of their industrial wastes. The applicability of bottom ash and green sand generated by industries as partial replacement of fine aggregates in cement mortar mix design is researched in this paper. Inorder to evaluate the effects of bottom ash and green sand admixtures on properties of cement mortar, the reference cement mortar without the admixtures is studied as well. The paper is also aimed to determine the optimum dose of the wastes to give a better performance. The influence of the admixtures on the mechanical performance is evaluated by measuring the compressive strength of the specimens. The analysis of the microstructure of the specimens is done by means of several techniques like X-ray diffraction method (XRD), Fourier Transform Infrared spectra analysis (FT-IR), Transmission Electron Microscopic method (TEM) and Acid attack test. The use of bottom ash and green sand as partial aggregate replacement in the composition of cement mortar also represents an alternative to final landfill disposal.
