Preparation of a Sand: Soil Mix – Procedure and Pitfalls

It is interesting to note that most of the sand in the mix comes from the soil. This is why the particle size distribution of the sand fraction of the soil is a critical laboratory requirement. The preferred procedure for mixing is with a front end loader and a power screen.
