Abstract

This paper investigated the influence of variation of moisture contents on the properties of Dukku natural sand for foundry use. The effect of moisture content on permeability, green shear strength, green compression strength, bulk density, and compatibility was investigated. In this work, the moisture content was varied from 1 to 8%. The particle size distribution of the natural sand, average grain size, grain fineness number, and the clay content of the Dukku sand were also investigated. From the investigation, it shows that 5% moisture gave the optimum green compression strength of 130. 5 kN/m2, while dry compression strength had an optimum value of 4505 kN/m2 with 8% moisture content. The grain fineness number of 61.51AFS with average grain size of 40.01 was recorded, while the permeability number showed a steady increase from 285 to 450 as the moisture content increased from 1% to 8%. The values obtained for the green compressive strength, the dry compressive strength, permeability number, and the grain fineness number indicate that Dukku natural sand has good values as a moulding sand and could used in the production cast irons and non-ferrous casting.
