Manufacturing Method of Concrete Block by Recycled Aggregate Using Plastic Waste and Concrete Block Manufactured by the Same
The present invention relates to a method for manufacturing a concrete block using plastic waste to prevent strength decrease of a concrete block and a concrete block manufactured thereby. According to the present invention, the method comprises: a pulverization process of pulverizing plastic waste composed of a mixture of one or more plastic materials; a mixing process of mixing inorganic additives in a predetermined ratio with pulverized plastic waste; a thermal injection process of putting the plastic waste and the inorganic additives into a screw extruder to perform extrusion and stirring, wherein heating is performed during stirring so that mixed aggregate having a density in a range of 0.75 to 0.85 g/cm^3 is formed; a recycled aggregate forming process of cutting the extruded mixed aggregate to form recycled aggregate in an elongated chip shape; a mortar mixing process of mixing 14 to 16 wt% of recycled aggregate, 59 to 61 wt% of natural aggregate, 24.5 wt% of cement, and 4 wt% of a water reducing agent with water to form mortar for a block; a concrete block forming process of putting the mixed block mortar into a vibration pressing machine to form a concrete block; and a curing process of curing the molded concrete block.
