Compressive strength of alkali activated slag with 10% of Wollastonite per mass reached a 7 day compressive strength of MPa (8000 psi). However, the estimated cost of this formulation is six times greater than similar concretes based on ordinary Portland cement. Different aggregates were tested to reduce the cost of this formulation.
Slag Cement Granulated Blast Furnace Slag 11 Benefits of the Concretes Produced with Blast Furnace Slag Cement Hydration The reaction between blast furnace slag cement and water is a complicated process. This involves the activation of the slag with alkalis and sulphates in order to form its hydration product. Some of these are
Alkaliactivated slag cement and concrete: a review of properties and problems Wang, ShaoDong ; Pu, XinCheng ; Scrivener, K. L. ; Pratt, P. L. This paper summarizes the advantageous and disadvantageous properties of alkaliactivated slag cement and concrete by reviewing previously published work in English, Russian and Chinese.
Slag, as an industrial byproduct, can be used to replace Portland cement and thereby the CO 2 emissions related to cement manufacturing can be reduced (Gartner, 2004, Juenger et al., 2010).
Effect of reactive magnesium oxide on properties of alkali activated slag geopolymer cement pastes Ceramics – Silikáty 59 (1) 3747 (2015) 39 Figure 2 shows the particle size distribution of GBFS, hydromagnesite and MgO calcined at 550, 1000 and 1250°C. It's can be found from particle size distribution that GBFS has about 90 % < 50 μm and
This paper examines the corrosion of alkaliactivated blast furnace slag cement in pH 3 nitric acid, pH 3 acetic acid, 30% CaCl2 solution and 15% CO2 atmosphere at relative humidity of 52%.
The use of Na2CO3 to improve the mechanical properties of highvolume slag cement (HVSC) is experimentally investigated in this study. Ordinary Portland cement (OPC) was replaced with 50, 60, 70, 80, and 90% groundgranulated blastfurnace slag (GGBFS) by weight.

Portland blastfurnace slag cement (PSC) was obtained by mixing of 65% ordinary Portland cement (OPC) with 35% granulated blastfurnace slag (GBFS). Very fine powder of cement kiln dust (CKD) was supplied from Turah Cement Company, Egypt, and condensed silica fume (SF) was provided by Ferrosilicon alloys Company, KomOmbo, Aswan, Egypt.
