A polygonal polymer concrete culvert is provided to improve compressive strength and flexural strength, to reduce a field accident at construction by making a product lightweight, and to make construction easy. A polygonal polymer concrete culvert, as a polygonal culvert provided with a through hole used as a common duct to install a cable on the inside or a water channel to flow out sewage, is composed of many unit culverts(3) manufactured with a polymer concrete composite, wherein many unit culverts are coupled by using a connector, and the polymer concrete composite is composed of 40~60 weight percent coarse aggregate, 15~25 weight percent fine aggregate, 15~25 weight percent filler, 7~9 weight percent polymer resins and 1~3 weight percent reducing agent. |
