Silica sol can be mixed with gypsum, wood chips, paper scraps and other scraps, pressed into shape, and dried to produce new wallboard materials and wall tiles, which can be used in energy-saving new building materials.
In the construction of concrete, adding silica sol equivalent to 0.1-0.3% of silica and polycarboxylate water reducer can effectively and persistently enhance the strength of concrete by 10-20%.
