DUST: Quality determines your success
Crusher Dust is made of a mixture of small crushed rocks and other fine aggregates, therefore it is able to provide a strong and sturdy surface. DUST is an aggregate that is usually used for parking lots, highway construction, pipe bedding works and so much more.
Being a developing country, we are under enormous pressure to replace fine aggregates in concrete by using alternatives without totally compromising the quality of the concrete.
The crusher DUST, satisfies this criteria and they serve significantly by being the best alternative for sand at lower cost. From the results of various experimental investigations conducted, it is concluded that the quarry dust can be used as a replacement for fine aggregate.
One of the findings is that, about 40% replacement of fine aggregate by quarry dust gives maximum result in strength than regular concrete. Quarry dust is a byproduct of the crushing process which is highly suitable for concreting purposes, especially as fine aggregates.
The studies done conclusively asserts the fact that, there is a consistent increase in the strength of plain concrete when natural sand is fully replaced by quarry dust. As the quantity of water increase in the mixture, the compressive strength decreases when replaced with quarry dust. This is due to the water absorption property of quarry dust.
Strength of the concrete is mainly dependent on bonding of the fine aggregates which fills the voids between the coarse aggregates. Crusher dust requires less water than other alternatives and have excellent load bearing capabilities, durability as well as being fire, heat resistant, and other corrosive elements such as non-plastic, alkaline earth metals while exposed to moisture, thereby making it an ideal material to use in construction.
The results proved that up to 40% replacement of sand by the quarry dust induced higher compressive strength and the workability of concrete decreases as replacement increases. Thus the environmental effects and waste can be significantly reduced.
