Abstract
This paper presents a comprehensive review of the lateral pressure exerted by self-compacting concrete (SCC) on formwork, highlighting the various influencing factors that contribute to this phenomenon. As SCC behaves like a fluid during placement, it generates lateral pressures that can significantly impact the stability and integrity of formwork structures. The study examines key parameters such as concrete properties, placement techniques, and formwork characteristics that affect lateral pressure dynamics. The review identifies that the density and fluidity of concrete are crucial in determining lateral pressure, with higher fluidity mixtures leading to increased pressure levels. Additionally, the rate of concrete placement plays a pivotal role; slower rates allow for early stiffening, subsequently reducing lateral pressures. The impact of temperature on concrete behavior is also explored, revealing that warmer temperatures can accelerate stiffening and influence pressure profiles. Moreover, the paper discusses how admixtures, aggregate shape, and size contribute to the overall behavior of SCC under lateral loading conditions. The findings underscore the importance of understanding these complex interactions to optimize concrete placement practices and ensure safe construction processes. This review aims to provide valuable insights for engineers and practitioners in the field, facilitating better design and management strategies for formwork in SCC applications.
