The invention discloses a pressure-free baking-free
brick for synergistically recovering
solid waste molten water-quenched
slag and
sludge incineration ash and a preparation method. The water-quenched
slag and the
sludge incineration ash are used as building materials to prepare the high-strength baking-free
brick. By utilizing a chemical component
complementation mechanism between two
solid wastes, through scientific formula design and combining process
route optimization, efficient fixation of
heavy metals and improvement of mechanical properties of the
brick body are realized, and the brick is high in strength and good in durability. According to the invention, the use of traditional brick making raw materials is reduced, and the adopted pouring molding technology is low in
energy consumption and less in carbon emission; according to the method, the two
solid wastes of the water-quenched
slag and the
sludge incineration ash are effectively consumed and converted into the
sintering-free brick value-added
building material, the secondary utilization value of the solid wastes is further developed, efficient
toxicity reduction of the water-quenched slag is achieved, environmental benefits and social and
economic benefits are both achieved, and the method is worthy of popularization and application. And a new
sustainable development direction is provided for
resource utilization of solid wastes and green transformation of the
building industry.
