Cement Additive - an overview | ScienceDirect Topics
Cement-bonded particle board: Wood particles (instead of fibers) are used in combination with Portland cement, water, and additives. Water, cement, and additives are mixed to produce the 'furnish' for board manufacture. The furnish is then directed to a forming machine, which deposits the material onto a moving conveyor to produce a mat.Get Price
