METHOD, DEVICE FOR MANUFACTURING A CONCRETE STRUCTURAL ELEMENT, AND THUS MANUFACTURED STRUCTURAL ELEMENT

摘要

The invention relates to a method for manufacturing a concrete structural element, w herein the method comprises the steps of providing a formwork closed on all sides and carrying the liquid concrete mass into the formwork via a pouring channel, wherein the liquid concrete mass is formed by concrete mass for forming concrete with a strength greater than or equal to that of high-strength concrete, and that during the pouring the formwork is de-aerated through de-aerating openings which are arranged in the lormwork and which are permeable to air but not to liquid concrete. The formation of air bubbles is greatly reduced as a result. The invention also relates to a formwork for forming a concrete structural element, wherein the formwork is adapted to form a concrete structural element with a strength greater than or equal to that of high-strength concrete, and that the formwork is provided with at least one de-aerating opening.
