This work sought to assess the suitability of using boards produced with plaster of Paris (P.O.P) and
various weight proportions of groundnut seed coat (GSC) as well as P.O.P and similar proportions
of waste newspaper paste (WNP) as ceiling in building design. The results obtained from the
investigation of thermal and mechanical properties of the fabricated boards revealed that with
the use of GSC as filler, the samples were of higher mean values of specific heat capacity, thermal
conductivity, thermal absorptivity, but lower mean values of bulk density, thermal diffusivity,
percentage water absorption, flaking concentration and flexural strength when compared to the
samples with similar proportions of WNP as filler content. Also, the sample with 13.8% content
of GSC and the one containing 22.5% of WNP were found to exhibit an impressive performance.
Generally, it was observed that the samples filled with either GSC or WNP were lighter than pure
P.O.P samples and the recorded values for all the measured properties favoured them for use
as ceiling material in buildings. It is noteworthy that the proportion of the filler can be adjusted
for optimum performance of such environmentally-friendly and cost-effective ceilings. Utilizing
groundnut seed coat and waste newspapers as filler materials in fabrication of P.O.P ceiling can
help to reduce environment pollution level, ensure better thermal insulation of buildings and
solve the lingering problem of high cost of using P.O.P or other conventional materials as ceiling
in buildings by the end-users.
