Resumo:
Soil is a raw material for making 'geotinta', an ecotechnologyof
high social and cultural value, which has been gaining
ground in the proposal for bio-construction and permaculture. To
obtain the geotinta, only soil and water are used, adding white glue
as binder; However, in the bio-construction scenario, replacing the
glue with a vegetable binder would add value to the product, due
to the current consunier market for biodegradable products. The
objective of this research was to evaluate the influence of plant
components (sap and resin) on the composition of the geotinta,
as attractive to the sustainable construction and handicraft
market. The resin used was produced by the ‘esponjinha’ (Albizia
lebbeck (L.) Benth.) and palm sap (Opuntia ficus indica (L.) Mill.),
Exotic plants, but adapted to the Northeastern semiarid. The
material was dissolved in water and added to different colored
soil samples previously destorroadas and sieved. The geotinta was
applied to ceramic pieces and cotton fabrics. preliminary results
were satisfactory, indicating the possibility of using material in
substitution glue, because the paint peeled nor was formation of
bubbles or cracks, however, future research should continue the
proposal.
