Precipitated Calcium Carbonate (PCC) from Sugar Processing Byproducts for use in Cementitious Applications and Methods Thereof

摘要

A process to make, in part, a refined material for use as crystallization accelerant in cementitious products. Evidence shows that calcium carbonate Fines (Ca⁺ ions) accelerate the crystallization process of CSH (Calcium-Silicate-Hydrate) phases which lends many advantages in cementitious products. The (PCC) fines materials from the sugar beet processing byproducts consist of these materials with various elements mixed or attached. This process selects for advantageous particles and discards others. This process includes, but is not limited to removing part of the undesirable material by either by screening or biodigestion of the lime to utilize energy contained in said unwanted material to dry in part said particles of PCC to specific moisture content and then screening the material to the remove more unwanted material and size PCC to spec necessary for cementitious materials.
