Acid Demand Test Silica Sand

Acid Demand Value ADV test reveals a moderately low ADV in samples of 20.09 signifying the presence of low soluble carbonates in the silica sand samples. Grain size distribution analysis reveals that a high percentage of the samples grains size distribution fraction are within the recommended screen sizes 40-100 mesh.
