The Carbonation Depth of Fine Recycled Aggregate Concrete

Popis výsledku v původním jazyce

This paper is focused on carbonation resistance of fine recycled aggregate (FRA) concrete. Durability of FRA concrete is connected with uncertainties and doubts. One of the most unknown aspects of FRA concrete is carbonation resistance. This paper presents results of carbonation depth of FRA concrete. The FRA was originated from crushed construction and demolition (CandD) waste. There were prepared a total four concrete mixture. The first mixture was reference, did not include FRA. In other concrete mixtures, natural sand was replaced by FRA in various replacement ratios, specifically 10%, 20%, and 30%. All prepared concrete mixtures were designated with the same parameters for clear comparison. From the test results it is possible to say that the use of FRA as partial replacement of natural sand in concrete influences carbonation resistance of concrete. Carbonation depth was higher for concrete samples with FRA. However it is possible to say that according to the carbonation resistance, the FRA concrete is possible to be used in the same applications as conventional concrete but it is necessary to verify that results.
