Description
The mechanical potential of sand core binders made withPinussylvestris has been examined. Ota silica
base sand bonded with 6% of cassava starch in admixed proportion of Pinussylvestris was tested for
tensile, compressive strength and permeability to establish the binding efficiency. Tensile strength of the
green baked core were oven baked at 50°C, 100°C, 150°C and 200°C.The cylindrically shaped
permeability specimens were tested with permeability meter. Study revealed thatPinussylvestris showed
an improve properties at 6% cassava starch at 200°C.
