Electro-Osmosis Applied for Formwork Removal of Concrete

Abstract

The release agents currently used to facilitate demolding and protect formworks from corrosion present some risks to users and the environment. This study focuses on a new demolding technique based on polarization, with the aim to eliminate the use of release agents. The tests were carried out on ordinary concrete C25/30 at 20±2°C. The methodology and conditions to obtain a good quality of concrete surface and demolding are presented herein.
