Physio-Chemical and Mechanical Behaviour of(Pinussylvestris) as Binders on Foundry Core Strength

摘要

The mechanical potential of sand core binders made withPinussylvestris has been examined. Ota silicaudbase sand bonded with 6% of cassava starch in admixed proportion of Pinussylvestris was tested forudtensile, compressive strength and permeability to establish the binding efficiency. Tensile strength of theudgreen baked core were oven baked at 50°C, 100°C, 150°C and 200°C.The cylindrically shapedudpermeability specimens were tested with permeability meter. Study revealed thatPinussylvestris showedudan improve properties at 6% cassava starch at 200°C.
