Thermal behaviour of alkali activated slag composites
Original language description
Portland cement is widely used as a part of many building materials among which the most common is concrete. This material is highly inflammable and does not support combustion of other material. However, its undesirable fast degradation, when exposed tovery high temperature, connected with compressive strength decrease, cracking and spalling limits the utilization of concrete in constructions endangered by fire. Concretes based on alkali activated slag exhibit a very good resistance against high temperatures and fire. This property can be improved by application of artificial thermally stabilized aggregates with low extensibility. We have examined the influence of burnt clay and andalusite on the behavior of alkali activated slag composite during heat loading up to 1200 C and the mechanical properties after high temperature exposure. The microstructure was investigated by mercury intrusion porosimetry and scanning electron microscopy.
