Abstract: Self-Compacting Concrete (SCC) is mainly used in France in horizontal applications, like slabs. This kind of structures is particularly sensitive to plastic shrinkage cracking since they offer a large surface area to drying. The purpose of this investigation is a comparison of free plastic shrinkage of Self-Compacting Concrete and Ordinary Concrete OC). Six SCC compositions and five OC compositions were tested. Mix compositions have different constituents and different compressive strengths. Plastic shrinkage was measured for all composition at 20°C and 50% HR by a device using laser sensors. For a same evaporation rate, plastic shrinkage amount of SCC was found to be at least two times higher compared to OC one. Based on the experimental results, the paper proposes some significant parameters for a better analysis of plastic shrinkage evolution.
