Changes of refractory composite's mechanical properties due to different temperature loadings
Original language description
This contribution is focused on investigation of refractory cement composite's properties after the action of different temperature loading. Examinee composite consists of aluminous cement, metakaolin and basalt aggregates. Combination of two lengths of basalt fibres was used as reinforcement. The experimental investigation deals with study of bulk density, compressive and flexural strength and fracture energy. All these parameters were analyzed on specimens with dimensions 40x40x160 mm after the action of various temperatures. The thermal loading was applied in range of 100°C to 1000°C with gradient per 100°C (100°C, 200°C, 300°C, ..., 800°C, 900°C, 1000°C) and took 180 minutes. Residual values of mechanical properties after thermal load on 1000°C achieved between 30% and 40% of reference level. The main part of mechanical propertie's decrease was described up to 400°C. The positive effect of basalt fibres was recorded especially on values of flexural strength and fracture energy. Residual properties after the maximal thermal loading on 1000°C level achieved still sufficient level for practical applications.
