    • A method for producing a block having a flat bottom, a flat top which is parallel to the bottom and sidewalls which extend between the bottom and the top is disclosed. At least three cooperating mold parts are assembled on a first plate to produce assembled mold parts having interior surfaces which conform with the shape of the sidewalls of the block and flat, coplanar tops and bottoms. The assembled mold parts are clamped together, and a high slump concrete which is hardenable by hydration of cement therein is charged and worked as required into close proximity to the interiors of the mold parts and to the plate inside the mold parts. A foamable composition capable of forming a body of a thermoset, closed cell, urethane foam having a density of about 10 to 60 pounds per cubic foot which fills the interior of the assembled mold parts above the concrete therein is then charged, and a second late is clamped over the tops of the mold parts. Preferably, there are small openings between the interior and the exterior of the mold through which excess water in the concrete can flow without appreciable loss of cement or aggregate from the mold.
    • 公开了一种制造具有平坦底部,平行于底部的平坦顶部和在底部和顶部之间延伸的侧壁的块体的制造方法。 至少三个配合的模具部件组装在第一板上以产生具有符合块的侧壁的形状和平坦的共面顶部和底部的内表面的组装的模具部件。 将组装的模具部件夹紧在一起,并且可以根据需要将能够通过水泥水泥硬化的高坍落度混凝土充填并加工成靠近模具部件的内部和模具部件内部的板。 能够形成密封约10至60磅/立方英尺的密封度的热固性,闭孔,聚氨酯泡沫体的可发泡组合物然后装入其中混合物之上的组装的模具部件的内部,然后第二次加载 被夹在模具部件的顶部上。 优选地,在模具的内部和外部之间存在小的开口,通过该开口,混凝土中的多余水可以流动,而不会从模具中明显损失水泥或骨料。
