Effect of Ukpor clay content on the properties of synthetic moulding sand produced from River Niger sand


Edoziuno FO, Odo JU, Nnuka EE

The effect of binder content on the moulding properties of Onitsha beach river Niger sand bonded with sUkpor clay has been studied. The samples were sourced from their deposits. Impurities and other foreign objects were removed by washing and sorting. The experimental samples were sieved and mixed in a Ridsdale laboratory sand mixer (Serial No: 845). AFS standard test specimens (50mm diameter by 50mm height) were prepared using Ridsdale laboratory sand rammer and six key moulding properties; green compression strength, dry compression strength, green shear strength, dry shear strength, green permeability and Mouldability were determined using a motor driven universal sand strength testing machine (Serial No: M8415), electric permeability meter (Serial No: 872) and mouldability tester. The results obtained showed a remarkable increase in green and dry strengths as the quantity of binder was increased from 10% to 12%. Further increase in the quantity of binder from 12% to 22% yielded a gradual increase in the strengths. High percentages of mouldability (90.57% to 97.36%) were obtained when the clay content was increased from 14% to 22%. The green permeability number showed a steady decrease from 11.00 to 7.00 as the quantity of the clay was increased from 10% to 22%. The results of moulding sand tests obtained from the produced synthetic moulding sand indicated that the sand could be used in the production of cast iron and non-ferrous alloys castings.
