| Description | Study is monitoring irreversible changes in concrete prefabricates in dependence of degradation factors in conditions of town district agglomeration. Attention is concentrate on degradation level of bonding agent and stone agent. Study is using metodes of polarization and electron microscopy, X-ray powder difraction, cathode-luminous metodes also chemical analysis, partial EDX analysis. There is a detailed description of bonding agent and distinguishing of carbonates by staining. There is main dependence between a concentration of acid-producting oxids and carbonation of concrete. The depth profiling of carbonates formed during a natural carbonation of concrete exposed to rain have been measured. Carbonation presented by micrite calcite in samples of concrete prefabricates from the surface to about 4 cm depth were detected. |
