Behavior of Cement Composites Loaded by High Temperature

Popis výsledku v původním jazyce

In this paper, there are summarized the results of an experimental program focused on basic, mechanical and thermal properties of cement composites according to the high ? temperature loading. Four different materials were studied, which differed in usedkind of cement and amount of fibers. As a matrix for studied composites the aluminous cement was chosen because of its resistance in high temperature. For a comparison the Portland cement was also tested. The second main ingredient used to provide better resistance in high temperatures - the basalt aggregate, was mixed in every specimen. The basalt fibers were chosen for two of the measured samples, remaining two ones were tested without fibers. The obtained data in this presented analyses show that the application of the aluminous cement leads to increase (depending on temperature) of porosity, which is the cause of decreasing of the coefficient of thermal conductivity. It can seems, that these cement composites will have low mechanic
