The solid particle contamination is a challenge for the cement industries due to the highly dusty environment. The contaminants cause severe wear between moving surfaces and this in turn leads to rapid mechanical failure of the machine elements. The solid particle contaminants get into the lubricant among the metal surfaces due to the environmental conditions. The conditions get more severe in ...

Granite powder (stone powder), a waste product generated from stone quarries, is increasingly being reused in cement-treated clays. The particle size of powders affects the cement-clay reaction by either increasing or reducing unconfined compressive strength (UCS). This study investigated this phenomenon separating same batch at quarry into five sizes (A, B, C, D and E: 106–75 µm, 40–75 20–40 &...
