Physical and Thermal Properties of Quarry Dust Reinforced ...

thermal conductivity reduction is due to the presence of 5.2% of porosity in the composite. The porosity reduces the conduction between the matrix and reinforcement materials. Also the quarry dust particle has lesser conductivity than the A356 alloy [7]. 4. Conclusions Castings of A356 alloy by adding different weight percentage of quarry dust

Strength and durability properties of quarry dust powder ...

As fineness of aggregate increases, thermal conductivity also increases. Increase in thermal conductivity might be because of the filler effect. The quarry dust due to its fine nature fills the voids in the mix. Since air voids are bad conductors of heat, reduction in air voids by its filling with quarry dust powder increases the thermal conductivity.
