Alkali Etched River Sand

Pre-etched river sand filler aggregate. Trying to add fillers & aggregates using natural sands will create staining issues and reduced strength from poor adhesion on sand grains and ion movement as metal ions from different coloured pieces of sand move along polymer chains. We provide pre-etched materials for non staining additives that will also bond better by chemical bonding along those etched surfaces. Washed and ready to use.
