Popis: | This study investigates the destruction of heat-resistant chamotte concrete of various classes: low-cement and medium-cement after exposure to thermal shocks. The influences of the addition of quartz sand (to increase alkaline resistance) and the addition of metal fiber (to reduce cracking) were also studied. Two methods were used to determine the heat resistance of concrete, according to the material destruction: a water-cooled plate method based on ultrasound and a method of unilateral heating-cooling. The results obtained via the method of unilateral heating-cooling revealed the formation of macrocracks in samples of low-cement concrete. This method was found to be more sensitive for evaluating concrete destruction. |
