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 ...
