In civil engineering applications, a lot of research has been conducted using shredded rubber and soil (sand/clay) mixtures, but from the images shown, it is clear that even in the laboratory, the homogeneous mix can not be achieved. However, researchers have ignored it and reported the data obtained through laboratory experiments.
Are there some efficient methodologies to make a homogeneous mixture using two materials that significantly differ in specific gravity (sand has around 2.5 times higher specific gravity than shredded rubber)?
In your application what is the size difference between the sand grains and the rubber shred? I suspect that the rubber shred needs to be much smaller than the sand, otherwise the sand will move through the rubber. The mixing ratios will also be important.
Forming a compound by mixing sand and waste takes a lot of time in terms of soil science. How do you want to do this?
Dear Ned Murphy ,
Thank you for your suggestion.
Consider the similar sizes of particles of sand and rubber.
In this case also, while focusing on standard methods of sample preparation for coarse-grained material, homogeneity cannot be achieved due to specific gravity contrast.

It is diffucult to handle this mix of sand and rubber. Basic materials are of different nature, and tought to mix them in uniform manner. Even if the rubber is made into small pellets or sand kind of consistancy, they start floating and seggeration happens. I agree, reserchers have ignored or not reported this issue.
