However, it has already been reported that the addition of dolomite in powder form to cement performs a comparable compressive strength to Portland-limestone cement [1,2]. Moreover, similar to limestone,
2019年6月30日 Calcined dolomite (CD) consists mainly of reactive CaO and MgO, which are the potential alkaline earth activators in the AAC pastes [37], [38], [39]. In the present study, a one-part Na 2 CO 3-activated slag dry mixture was prepared by mixing blast furnace slag with sodium carbonate powder and CD. The dry mixture only needed the water
2021年8月11日 The studies of hydration process in the mixtures of cement with limestone powder, dolomite powder and limestone dolomite additive were reported by Nocuń-Wczelik et al. [6]. In the pastes hydrating with fine grained dolomite powder the crystallization of products is accelerated and as a consequence the strength development is improved.
