Abstract: Due to the high amount of filler materials, e.g. limestone filler, the hydration processes of the cement can slightly be altered within self-compacting concrete. This is confirmed by means of adiabatic hydration tests on concrete and isothermal hydration tests on cement-powder mixtures. The overall reaction kinetics is somewhat increased. Furthermore, new reaction mechanisms, causing an extra heat production peak, can be introduced due to the high filler content. An important factor in this seems to be the C3A-content of the cement. The resulting hydration processes in limestone filler rich self-compacting concrete can be modelled mathematically taking into account the cement-powder ratio as an important parameter. Furthermore, the properties development of hardening self-compacting concrete is studied. It seems that the degree of hydration concept and the maturity method can still be applied to selfcompacting concrete.
