Study of Interaction between Fly Ash-cement and Bentonite Matrices
VŠB – Technical University of Ostrava, 17. listopadu 15/2172, 708 33, Ostrava – Poruba, Czech Republic
Among the important factors characterizing the quality of sealing mixtures is strength, durability, compatibility and permeability. Experimental work was therefore conducted to assess the use of cement, fly ash, gravel and bentonite in the form of artificial self-hardening sealing mixture. The results of the work show a good compatibility between the bentonite and cement during its fly ash replacement. Compactness of the structure was confirmed by studying of permeability and SEM microscopy, which in the system of ash-cement-bentonite matrix allowed assessing successive microstructure development of hydrating gel.
