Original Abstract

The paper presents the results and findings of the research focused on an examination of progressive degradation of newly developed composite materials. These materials consisted of a polymer-silicate matrix and a mix of fillers with a considerable proportion of a porous aggregate. The matrix also contained a larger amount of alternative raw materials, in particular hightemperature fly ash and blast furnace slag. Prepared mixes were tested after different periods of exposure to an aggressive environment – for 45 d and 90 d (50 and 100 cycles). First, after 45 d and 90 d, reference materials (i.e., those not exposed to aggressive influences) were tested. In parallel, tests were carried out with materials exposed to a solution of chloride ions and subjected to cyclic freeze and thaw. The last mode of testing in this research included materials exposed to cyclic freeze and thaw, chloride-ion solution and the consequent thermal load of up to 1000 °C.
