Conversion of Marble Waste into a Value Added Composite Materials for Civil Infrastructure
Material type: TextDescription: 239-250 pSubject(s): In: CHAKRAVORTY S K (EDITOR) PRODUCTIVITYSummary: During marble processing, cutting and polishing, more than 12 MT (million tons) of marble waste per year has been produced only in the state of Rajasthan, India. Safe disposal of such huge quantity of marble wastes become a major environmental issue. In the present study, attempt have been made to recycle marble waste collected from Makrana marble processing industries, Rajasthan, as raw materials, for making composite materials. Characterisation studies showed that the major mineral present in marble waste are Calcite (CaCO3), Dolomite (CaMg(CO3)2) and Quartz (SiO3). Composite materials were made using marble waste reinforced with jute textile fibres in epoxy resin system. The findings of the study showed that marble waste composites reinforced with jute textile have resulted about 50% higher flexural strength (48.48 MPa) than the commercially available MDF (medium density fibre) board (24.23 MPa). It also showed very low water absorption (24 hour immersion) and thickness swelling. The microstructure of fractured surface of marble waste composite showed very good bonding between the marble waste, fibre and the matrix. The composite materials have multifunctional applications in civil construction sector, transport system as doors, false ceilings, architectural wall panels, partition and furniture etc. The marble waste composite materials are stronger than teak wood and other traditional materials such as medium density board, particle board, and rice husk board. Commercial realisation of this composite technology would significantly contribute to Nation program on clean India, make in India and advanced manufacturing missions. Efforts are being made to ease the commercialisation of this technology.Item type | Current library | Call number | Vol info | Status | Notes | Date due | Barcode | Item holds | |
