Title:
METHOD FOR PRODUCING WATER PERMEABLE BRICK USING DREDGED SEDIMENT FIRING-FREE AGGREGATE
Document Type and Number:
WIPO Patent Application WO/2020/118804
Kind Code:
A1
Abstract:
A method for preparing a water permeable brick using dredged sediment firing-free aggregate. The method comprises the following steps of: (1) screening the dredged sediment firing-free aggregate; (2) preparing pretreated firing-free aggregate; (3) preparing base layer ingredients; (4) adding water to the base layer ingredients and stirring the mixture; (5) preparing face layer ingredients; (6) adding water to the face layer ingredients and stirring the mixture; (7) performing press molding by a brick machine; and (8) maintaining the manufactured product. The method can consume a large amount of dredged sediment, reduces exploitation of natural aggregate, achieves the purposes of recycling and ecological environment protection, and meets demands of dredging industry; the used firing-free method is low in production energy consumption and less in emission, the produced water permeable brick is low in cost and excellent in performance, the dredged sediment recycling approaches can be widened, the demand of a building material market can be met, and the "urban heat island effect" can be well relieved.
