In Sand/PE composites, can we apply any surface treatment to increase the strength? any suggestions? any other methods?
Silylation (silanation) is old and sure method for adhesion improvement. For instance, treatment with hexamethyldisalazane or trialkoxy alkylsilanes (trimethoxy- or triethoxy methylsilanes are common)

Hi, see these links

In addition to the surface treatment the reproducible particle size distribution is very important, as it may change the mechanical properties drastically. Without that even surface treatment does not help.
Your processing method will make a difference. Is your composite resulted from melt processing or waterborne processing? Different conditions lead to different stories.
Just deposit a thin film in a C2H4-fed plasma on sand particles in a rotatiing reactor. The rotation is important to coat uniformly sand particles. The selection of C2H4 ensures you are coating the sand particle with a polyethylene-like film. In other words the sand particles and PE will look alike.
Since PE is hydrophobic never deposit a coating which is hydrophilic for improving adhesion with PE. Remember the old chemical motto" the similat likes the similar".
