Recyclinj Of Agregate In Portland Cement

Recycling of steel slag aggregate in portland cement ...

2021-2-1  Compared to Portland cement, the cementitious phase of steel slag is inactive. The hydration rate of steel slag is significantly slower than that of cement at early age, which can be demonstrated by the hydration exothermic curves of steel slag (Sun et al., 2020). Most cementitious phases in SSA finish hydration after 90 days. (Wang and Yan, 2010).
