Abstract

In civil engineering construction, mass concreting of a thick foundation slab is not uncommon. The non-stop operation could lead to elevated temperature above 90°C. It is derived from the exothermic chemical reaction. The elevated temperature favors the delayed Ettringite crystal formation, which would generate micro-cracks and hence deteriorate the strength of concrete. This paper presents a review and a project to validate the delayed Ettringite degradation through a simulated laboratory environment.
