dc.description.abstractIn achieving accelerated and sustaining economic growth and development in Nigeria, there is need for domestication of finished goods production through sustainable industrialization. Foundry technology is one of the vital bases for rapid industrial development of any nation. Samples of moulding sand at green state were collected from four different moulding sand deposits within Ado-Ekiti in Nigeria. The samples were prepared using ASTM and British standards, while the materials’ Physico-mechanical properties were evaluated using American Foundry Society (AFS) guidelines. The results obtained from the tests were compared with the AFS’s satisfactory mould sand properties for various types of metal castings. The sand samples were found to meet the requirements for casting various metals of different types like Aluminum, brass and bronze, light and malleable iron, light and medium grey iron, except heavy steel. The presence of red oxide in the sands and the specimens’ higher compressive strength values show that the natural sands will be suitable for casting of non- ferrous metal of low temperature. Effective application of the sample sands in casting will also enhance industrialization, job creation and the nation self-reliance through reduction in importation of foundry sand and foundry products into the country.en_US

Description:
The sand samples are found to comprise chemical compositions which are within the AFS acceptable limits for moulding sands. The sand samples exhibited high quality of silica suitable as raw sand for low temperature ferrous and nonferrous metal castings, except that of Omi Amun moulding sand sample which has a bit lesser value of silica oxide. This property can be enhanced by application of additive like bentonite to meet the required limit for most metal casting. ii. The results of physico-mechanical properties of the sand samples revealed that studied mould sands’ properties are comparable with the standards. Thus, they can be effectively used for adequate casting. iii. The physico-mechanical properties of the sand samples also revealed that the sands can be suitably used in casting of metals like grey steel/iron, light steels and aluminum, except heavy steel. iv. The presence of red oxide in the sands and most of the specimen compressive strengths are in their highest value show that the natural sand in Ado-Ekiti will be suitable for casting of non- ferrous metal of low temperature.
