摘要: Abstract This study deals with curing of mortars in which coal ashes from both PC and FBC boilers were the sole binder components. The work focuses on hydration products results are correlated physical properties cured beams 10 formulations mortar made sand ash blends. Curing was extended to two three years beam specimens water for swelling measurements moist atmosphere shrinking measurements. Mechanical strength dimensional stability tested periodically porosity also made. Separation by density pulverized samples performed obtain light fractions containing hydrates formed. these separated analysed identified included AFt, gypsum, portlandite, a variety hydrated calcium aluminosilicates amorphous C–S–H. composition C–S–H, as characterized atomic ratios various elements referred Ca indicated considerable replacement Si Al S. degree hydration, percentage fraction or other properties, chemical characteristics blends related mechanical using novel indices. One relates silicoaluminous sulphocalcic components available free lime sulphate content mortar.
