Experimental Analysis of Hydrothermal Curing Influence on Properties of Fiber-Cement Composite

摘要

Special industrial application of fiber-cement composites is currently one important issue of concrete industry and research activity. The field of refractory and high-temperature resistance materials is very large and contains the cement composites, too. Hydrothermal curing together with using aluminous cement with refractory basalt aggregates and fibers shows high potential for its applications at high temperature. This composite is characterized by compressive strength over 140 MPa and tensile strength in bending 12 MPa (investigated on specimens 40 × 40 × 160 mm). After exposure to temperature 1000°C these parameters are 60 MPa in compression respective 6 MPa in bending. Achieved values are significantly higher than in the case of laboratory curing condition and they are suitable especially for prefabricated fire resistance cladding or other special application in the industry.
