Publication Date : 01/02/2007
The Challawa river bed sand commonly used by Kano founders was analyzed. Various additives were mixed with the sand and analyzed with the aim of determining an optimum mix in preparing molding sand that can produce a very good sand casting. The physical properties were investigated based on the addition of various percentages by mass of water and Kaolin clay. The result of the test show that the Challawa river sand mixed with 4% water and 20% clay produces a molding material with a good range of properties that can result in a good casting. This mix is thus recommended for use of founders.
