The Characteristics of Recycle Plaster of Paris at Different Drying Temperatures

Open access
The industry ceramic represents a large solid waste dumping and concerning environment damaged cause. As we know in Malaysia, ceramic industry very famous especially in Kuala Kangsar, Perak. According to Nawi (2016) the Department of Environment (DOE), 337,770 metric tons of plaster of Paris became solid waste in 2012, up from 80,000 metric tons in 2009. This shows an increase in solid waste is increasing. In this way, the aim of this study is to identify the chemical and physical properties that the used Plaster of Paris (POP) can be recycled as new plaster without affecting their casting performance. This paper showed the comparing the characteristic properties of New Plaster of Paris (NPOP) and Recycle Plaster of Paris (RPOP) at differences drying temperature. This experimental started with recycle used mould, crushing, sieving, drying in oven at variation temperature (150?,160?,170?,180?,190?) for 1 hour and tested with setting times, particle size, absorption test, porosity, and used the same ratio 40% of water and 60% material during the mixing process. The result show that all sample Recycles Plaster of Paris at variation temperature are performance and can be working similar New Plaster of Paris.
