But this material canot be used directly alternative of cement because percentage of chemical composition of cement is different than waste. The main components of blast furnace slag are CaO (30-55%), SiO2 (22-36%), Al2O3 (6-22%), and MgO (1-18%). In general increasing the CaO ...
The assumption that chemical binding capacity is controlled by alumina phases is supported by multiple linear regression analysis that was conducted to assess the relationship between Fruendlich isotherm constants and the concrete’s chemical composition. To determine the effect physical and/or chemical ...

In traditional cement based binders, strength is lost through chemical attack upon exposure to solvents. 2011 Institute of Materials, Minerals and Mining.doi:10.1179/1743676111Y.0000000048Gordon, L EProvis, J Lvan Deventer, J S JtaylorAdvances in Applied Ceramics...
Chemical composition and mineralogy of the precursor materials; Quantity, shape (solid, liquid) and type of alkaline activator; Si/Al ratio of precursor materials and quantity of available calcium sources such as Portland cement, blast furnace slag and lime; Total water/solids ratio (precursors + ...
This study provides the results of an experiment on the possibility of using high-volume ground granulated blast furnace slag (HVGGBFS)-based concrete as mass concrete. In addition to the control concrete, the total weight of the binder was 75% ground gr
Testing showed that moderate dependences between those parameters and activity indexes were observed. Results showed that prediction of activity indexes based on chemical composition is feasible.KovacFacultyMarekFacultySicakovaFacultyAlenaFacultySpakFacultyMatejFacultyMDPIProceedings...
