The partial replacement of Portland cement and silica fume by ground granulated blast furnace slag in DSP cement pastes has been investigated under different curing regimens. The influence of long‐term hydration at 25°C, as well as hydrothermal curing (at 80°C) and strong drying (at 200° and 400°C), on the composition and microstructures of slag–Portland cement DSP materials was investigated by nsing QXRD, TGA, MIP, and TMS‐GPC methods in this study. Slag is found to be an additive improving intrinsic properties of the DSP paste. CaO/SiO 2 molar ratios of C‐S‐H phase in the DSP cement past have been calculated.
