Abstract

In this investigation, the Ochadamu silica sand was analyzed and used as base sand for the Ochadamu clay- sand mixture in an attempt to improve and develop an efficient foundry core. The mechanical properties of the sand, clay, and local oil mixture were determined. The fitness number, total coarse fraction, and the total fine fraction of Ochadamu silica sand were found to be within the best range that will give good molding properties and core durability. The values obtained for the cold compressive strength, permeability, hardness, dry shear strength, and shattered strength indicated that Ochadamu sand and clay have good values as a binder for foundry core making in general.
