Abstract
Described herein is a cementitious article and a method of making using a water-based manufacturing system that incorporates a closed-loop or partially closed loop water recycling system and an alkali removal process. The system, as such is environmentally friendly, saves resources, such as water and other raw materials, and reduces waste disposal. The system further provides for a cementitious article having a low alkali content. Articles prepared by one or more processes described herein have characteristics that include a low apparent density, high strength and high freeze-thaw performance as compared with an article of the same general formulation but made from a comparative manufacturing system that does not include an alkali removal process. Articles described herein are suitable for use as building products, such as siding, the underlayment panel, board, trim, fascia, roofing, decking, and fence.
