Experimental analysis of various temperature loadings influence on cement composite

Popis výsledku v původním jazyce

This contribution deals with the experimental investigation of mechanical, fracture and basic properties of refractory cement composite after the action of various temperatures loadings. Investigated refractory cement composite on aluminous cement based with high dosage of metakaolin was reinforced by basalt fibres. The temperature loading was especially focused on temperature between 700°C and 1000°C (grading after 100°C) and between 100°C and 700°C (grading after 200°C). The bulk density, dynamic modulus of elasticity, compressive strength, flexural strength and fracture energy were investigated after the action of mentioned temperatures. The action of temperature between 300°C and 500°C means the highest decrease of mechanical properties. The percentage decrease of flexural strength and fracture energy was higher than compressive strength. The decrease of investigated properties after the action of temperature higher than 700°C was gradual and not so rapid. The residual mechanical properties after the action of 1000°C achieved sufficient values for cement composite with natural aggregate.
