Abstract
The invention is a method of manufacturing construction precast elements made of porous construction materials, especially composite materials with open structure of pores, cured under normal temperatures, such as concretes, where these construction materials are formed of a mixture of aggregate and bond. Unsorted plastic waste is added into the mixture of aggregate and bond. Such unsorted plastic waste is freed from dirt, crushed and shaped into granules. These granules of plastic waste are mixed into the mixture of construction material before curing. When cured, the resulting precast element is heated to a temperature causing at least part of the granules to melt into a fully liquid state. The resulting composite element is allowed to cool. The plastic waste becomes an additional bond in the precast elements.
