Quarry dust a by- product from crushing process during quarrying activities is good alternative during construction projects. It is used as substitute to sand to make concretes, which are believed to be stronger and more durable than the regular concrete materials.
It can be used as substitute to sand wholly or partly. It offers a comparatively good strength compared to sand with or without concrete admixtures. Many road and home builders have opted to use quarry dust.
Check out the benefits of using quarry dust:-
1. Strength When Needed
Sand is obtained from riverbeds, and is its availability is becoming challenging at reasonable price. In order not to compromise strength of building during construction, the dust come handy as an equal substitute without threat to quality at the same time rendering good strength to constructions.
2. Saves Cost
Construction Projects that use quarry dust have proven to be cheaper than those that depend wholly on sand. The dust come at cheaper cost and lesser pressure on market demand for sand. Partial replacement of sand with this dust will make good concrete that is well desired in residential construction. The final product is strong bricks, slabs or tiles that are produced at lower cost compare to using sand.
3. Easily available
As compared to sand and cement, the quarry dust is easily available. It requires less processing and it being a byproduct of quarrying, it is very accessible at large quantities for a cheaper cost. Many quarry owners dispose it at very low prices making it almost always available.
4. Quality maintenance
Quality of construction is the most important aspect under consideration. The dust improves the mechanical properties of concrete as well as durability. Quarry dust has been proposed as an alternative to river sand that gives additional benefit to cement during construction.
5. Consumption reduces the pollution in environment
In areas where constructors use this dust, there is a significant reduction of air pollution by the dust. Quarry dust is very volatile and its inhalation can cause respiratory problems. Inclusion of the dust in construction projects will solve the problem of disposal of this dust.
Conclusion
Addition of quarry dust improves the physical and mechanical properties of concrete. Due to its high volume of fine particles, it proves to be very effective in assuring very good cohesiveness of concrete.
The shift in demand for sand in construction is ongoing it will not be something unimaginable to see constructors use quarry dust to replace sand in future constructions.
