THE MICROSTRUCTURE OF HIGH STRENGTH BLAST FURNACE SLAG CONCRETE

The microstructures of the blended cement concrete, alkali activated slag concrete and Portland cement concrete were compared. The structures of the samples and the compositions of the hardening products were investigated by means of porosity studies, optical and scanning electron microscopy, thermoanalysis and X-ray studies. In the alkali-activated and auto-activated slag concrete the structure contains microcracks at the microscopic level. According to the SEM studies the hardened structure of alkali activated glassy slag is composed of smooth granular products, while the fibre type hardening products are lacking.
