Abstract

A manufacture method for concrete section is invented for concrete of high fluidity and capped mold frame. By the process of pumping the concrete into the closed mold frame made of apertured steel plates with cap to form the section, the finished surface is so smooth that there^s no need for vibration solidification and surface reworking.
