To perform various strength test on core and mould sand

I. Compression strength test for moulding sand
II. Shear strength test for moulding sand
III. Tensile strength test of core sand

Learning Objectives:

LO1- To understand the Importance of Sand Strength Tests – significance of compression, tensile, and shear strength in moulding and core sand to ensure defect-free castings.

LO2- To analyse the Testing Procedures – Performing compression, tensile, and shear strength tests using a universal sand testing machine while following standard procedures.

LO3- To understand Factors Affecting Sand Strength –how moisture content, binder percentage, grain size, and compaction pressure influence the mechanical strength of moulding and core sand.

Material used:

Base sand, clay, water

Apparatus used:

universal sand testing machine, Split core box, Sand rammer, oven, tension, Shackles, weighing pan
