When comparing stone dust vs sand, this sand is definitely an acceptable material to use under pavers. It provides drainage, wont eat away at the pavers, and it compacts well. With the compaction of the pavers, the sand will work its way into the joints of the pavers from below creating that interlock that is required in an interlocking system.

Carbonate weathering by rain is considered to play an important role in the karst landform evolution. Rock outcrops (or stone teeth) are frequently visible on the earth's surface, especially in karst landscapes, but there is no consensus on how they appeared or increased in number. This study estimated the extent of rain-induced weathering dissolution of limestone using hydro …

Limestone aggregate concrete is a type of concrete that uses crushed limestone rocks instead of regular gravel and sand. This limestone is naturally packed with a substance called calcium carbonate, which is similar to cement. When regular cement is mixed with water to make concrete, a chemical reaction helps everything stick together and harden.
Therefore, the research on the mechanism of the influence of limestone powder on the mechanical properties of concrete was carried out by using nano-indentation, super depth-of-field microscopy, LF NMR, and other testing techniques on the mechanism of sand concrete with a water-cement ratio of 0.45 as the research object.
