Stone crusher dust as a fine aggregate in Concrete for

2017-12-12 Concrete paving blocks are ideal materials on the footpaths for easy laying, better look and finish. In this paper, a parametric experimental study for producing paving blocks using crusher dust is presented. Some of the physical and mechanical properties of paving blocks with fine aggregate (sand) replaced by various percentages of crusher dust are investigated. The test results shows that the replacement fine aggregate by crusher dust up to 50% by weight has a negligible effect on the reduction of any physical and mechanical properties while there is a saving of 56% of money. The percentage of saving was less but highly beneficial for mass production of paving blocks. The shaving would be more if the sand availability is at a greater distance. This also reduces the burden of dumping crusher dust

What is Stone Dust and Why Would You Get It? Nimvo

There are pros and cons to using stone dust for paving compared to using sand. Many landscapers prefer to use sand with concrete as the base material and to use stone dust only for between the paving stones. However, if you choose crusher run, it has better properties for using as a base layer for paving than regular stone dust.
