EXTRUDED PLASTIC AGGREGATE FOR CONCRETE
The invention generally relates to a method of making a plastic aggregate, and its use to make concrete products. The aggregate is formed by providing a granulated waste plastic material, introducing the granulated waste plastic material into an extruder having a die, the die having a ratio of die nozzle open area to die land area of about 1:10 to about 1:40, and extruding the granulated waste plastic material through the extruder to generate an extruded plastic aggregate. The method can include the presence of controlled cooling, the addition of additives and treatment of the surface of the aggregate to produce a desired aggregate that can be used to make a concrete product with desired properties, such as compressive strength and weight.
本发明总体上涉及一种制备塑料骨料的方法以及其用于制备混凝土产品的用途。通过如下方式来形成所述骨料，即：提供颗粒状废塑料材料，将颗粒状废塑料材料引入具有模具的挤出机，所述模具的模嘴开口面积与模具工作带面积的比为约1:10至约1:40，以及通过挤出机挤出颗粒状废塑料材料以产生挤出的塑料骨料。该方法可以包括存在受控冷却、添加添加剂和处理骨料表面以生产所需的骨料，所需的骨料可以用于制备具有所需的性能如压缩强度和重量的混凝土产品。
