发明名称 Method for making antiqued concrete cored bricks and capping bricks
摘要 A method for making concrete cored bricks and capping bricks includes providing a mold having a row of mold cavities separated by cross members having core-bar holes formed therein, inserting a core bar through each cavity and into and filling a core-bar hole associated with rear cavity. Next, a rear core-bar hole is plugged and the cavities are filled with a concrete to form plural uncured bricks. The bricks are then compacted and an elongate, interconnecting pattern is pressed into a first surface of each brick. Next, the core bar is removed from the cavities and the bricks are ejected from the mold. Finally, plural wet layers of colored coatings are applied to the first surface of each brick after which the bricks are cured. Antiqued concrete capping brick including a top surface, four side surfaces, and a bottom surface having formed therein at least one recess are also formed. Additionally, a first side surface of the brick includes elongate, interconnected indentations that extend to the edges thereof. Also, adjacent the edges of the first side surface, there are edge-indentations in the brick to provide a rolled edge effect. Finally, plural layers of colored polymeric coatings are disposed on the first side surface and a top surface of the brick.
