Advanced self-compacting concrete performance in the fresh and hardened state

Abstract

Advanced Self-Compacting Concrete (SCC) is a highly flowable concrete that completely avoids vibration during casting. This paper explains the properties and performance in formwork of this highly flowable SCC, and the lateral pressure exerted on the sides of the formwork. In this investigation, a lightweight plastic system panel was used to cast the concrete column. The reactions of materials in real time and how the process of hardening occurs were investigated. Thus, this study discusses the casting rate, rheology, workability, lateral pressure, and plastic shrinkage of SCC. Using Digital Image Correlation, it also discusses physical and mechanical properties at early ages and at the hardening stage of 28 days. The properties at these time points are critical facts that should be considered during the design of formwork. In this paper, the most advanced techniques are used to measure lateral pressure exerted at different heights on the sides of the formwork.
