AbstractThe paper discusses results of the research into the influence of high-alkali Portland cement on granite aggregate. The deformation of the concrete structure occurred after 18 months. The research was carried out by means of a scanning electron microscope equipped with a high-energy dispersive X-ray analyzer that allowed observation of unpolished sections of concrete bars exhibiting the cracking pattern typical of the alkali–silica reaction. Both the microscopic observation and the X-ray elemental analysis confirm the presence of alkali–silica gel and secondary ettringite in the cracks.
