APPLICATION OF STONE DUST FOR CEMENT AND BENTONITE MIXTURES

Abstract
The objective of this study is to determine the potential applications of stone dust for cement and bentonite mixtures. Results indicate that stone dust with particle size ranges of 0.25 mm and larger is suitable for cement mixtures as they show compressive strength and elastic modulus values comparable to the cement- fine sand mixtures. The particle size ranges of 0.25 mm and finer are suitable for hydraulic containment applications. The weight ratio of stone dust to bentonite of 40% is recommended as its mixtures show the highest dry density,and frictional resistance with lowest optimum water content. Results from swelling test also support that at 40% stone dust content the swelling capacity of its mixtures is about 50% of that of pure bentonite. The separator between coarse and fine grained stone dust at 0.25 mm allows the applications stone dust to construction industry and hydraulic containment work.
