This paper presents a summary of an extensive research project that aimed at developing formulation expertise and guidelines to lower lateral pressure of Self-consolidating concrete (SCC). The project was sponsored by the National Ready Mix Concrete Foundation and the Strategic Development Council of the American Concrete Institute. The paper highlights the development of a pressure column devise that can be used to predict lateral pressure exerted by SCC as well as empirical test methods to determine the structural build-up at rest of SCC,which is shown to significantly affect formwork pressure. The role of material constituents,mix design, concrete casting rate, formwork geometry, and temperature on SCC form pressure are highlighted. Proposed design equations to predict formwork pressure of SCC on column and wall elements are also presented.
