Abstract

In this study, a new wall plaster product was generated using 0-5% perlite, 0-2.5% waste paper and 3.5-17.7% waste calcined borax. The optimum ratios for the additives were 3% perlite, 1.5% waste paper and 7.1% waste calcined borax. The new plaster was subjected to mechanical strength and thermal transmittance measurements using TS 825 and TS 12808-3 Turkish standards. Under optimal mixing ratios, the plaster had a thermal conductivity of 0.17 W/m(2)K and a mechanical strength (bending) of 61.44 kg/cm(2) 2K. V. The required standards by TSE 825 are 0.13 W/m(2)K the new product was compared with the existing plasters in the market, it was observed that thermal transmittance and mechanical strength were both increased by 26% and 31%, respectively. Thus, a new environmental-friendly wall plaster product was produced.
