Fracture response of cement-based composite with spherical glass aggregate exposed to high temperatures

Popis výsledku v původním jazyce

Paper concerns an investigation into the effects of high temperatures acting on specimens made from specially designed fine-grained cement-based composite with spherical glass aggregate. The experimental programme was carried out on four sets of beam specimens with the dimensions 20 × 40 × 200 mm. The specimens were thermally loaded to pre-set temperatures of 100, 200 and 400°C. After the temperature loading had been performed, the specimens were left to cool down to ambient temperature and fracture tests were used to determine the degree of damage caused to the specimens by temperature loading. Three-point bending tests of notched specimens were conducted. Fracture response was evaluated via load versus deflection diagrams. The monitored parameters were modulus of elasticity, effective fracture toughness and specific fracture energy. Informative compressive strength values were also determined. Selected specimens were investigated using X-ray microtomography (micro-CT).
