Studies on Lime Sludge for Partial Replacement of Cement

Abstract:

Utilization of industrial and agricultural waste products in the construction industry has been the focus of research for economical and environmental reasons. In this paper, Lime sludge, a paper and pulp industry waste product, has been chemically, physically and thermally characterized, in order to evaluate the possibility of its use as construction materials. X-ray Fluorescence and X-ray diffractometry studies for the determination of composition and presence of crystalline material and Thermo Gravimetric Analysis to identify the phase transition of lime sludge, as well as physical and mechanical properties and its pozzolanic activity have been conducted. It is concluded that the acceptance of this waste product by the construction industry could be decided depending on the application, keeping in view of the limitations on the mechanical strength.
