Foundry operatives have been conducting laboratory tests physically and characterizing silica sand of river bed for moulding purposes with a view to ascertaining their properties. This has made flexibility and speed of decision-making difficult during moulding practice. This study was aimed at developing a model and simulation for estimating the moulding behaviour of river Niger coarse sand at different clay contents. Physical tests were carried out on 90 samples of coarse sand/clay/water composition. Experimental data obtained from the physical tests were used to develop modeling equations. The equations were then used to develop the software for simulation. Statistical tests were used to validate the developed models. The GFN of the coarse sand was 42.42%. Grain distribution indicated a normal curve showing the different sizes of sand that aided sand mould compactability. The trend of the relationship properties and clay content indicated linearity in compactability (38-50), green hardness (55-82), green shear strength (0-160) and shatter index (38-55) while an inverse linearity was observed in permeability (150-125). However, green compression strength which maintained a steady positive relationship from 5-9% clay showed a fluctuating pattern up to 13% clay. The model equations predicted the output close to the experimental results using Silica Sand Mould Properties Determination (SSMPD) software. The software was developed using VISUAL BASIC programming language. It is user friendly and runs on Window computer of at least 1 MB RAM and 3.0 GB free hard disk with information on the installation, running and using the application software. This SSMPD has contributed to rapid determination of coarse sand properties for foundry mould practice.
