Abstract:
Contractors are interested in removing the formwork from concrete walls as soon as 12 hours in order to reuse these forms. While these walls may have sufficient strength, there is concern about the long-term durability of removing the forms at early ages. Curing is known to maintain the concrete moisture and promote hydration towards a denser microstructure and improved durability. This research aims to investigate the impact of different curing methods after form removal at different times on both drying rate and ion penetration into concrete. Rapid drying on young concrete can cause cracking if the element is restrained, like a wall, which exacerbates ions and moisture penetrations leading to corrosion and other durability issues. This study provides quantitative values for mass loss and chloride concentration using Micro X-ray Fluorescence which gives insights into the service life of their concrete and help choose more reliable curing methods, curing duration, and form removal times.
