Abstract
Abstract The use of eco-friendly materials are now becoming the field of interest in construction industry to ensure sustainability and healthy living. Gypsum plasters are eco-friendly building materials but are brittle in nature and hence reinforcement of these plasters using fibres has been found to be beneficial at its post tensioning stage. In this present work the control of harmful ecological impact of Prosopis juliflora invasive species by their effective utilization in building plaster is proposed. To assess the performance of this environmental friendly building plaster using Prosopis juliflora fibres the physical properties such as setting time, temperature rise and density were measured. Furthermore the Prosopis juliflora fibres were subjected to various chemical treatments (NaOH, KmnO4 and distilled water) and the effect of these treatments on the interaction of fibre with gypsum plaster was evaluated in terms of mechanical strength characterization. Based on the observed results the enhancement in flexural strength of the plaster was observed coupled with the transformation of brittle failure to ductile failure. The toughness of the composites were also much enhanced with the addition of the fibres.
