    Chemical Admixtures - cement.org

    Accelerating admixtures are especially useful for modifying the properties of concrete in cold weather. Superplasticizers , also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.

    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.
