Experimental Determination of the Influence of Water/Cement Ratio Value on the Resistance of Concrete to the Action of Water and Chemical Thawing Agents

Popis výsledku v původním jazyce

The assessment of the surface layer is rather complicated and therefore the project involves the use of the available standardised and non-standardised test methods, using which the concrete surface layer or its internal structure can be characterised. Determination of resistance of cement concrete surface to water and defrosting chemicals is one of such methods and is commonly used. The paper presents the results of experiments performed with concretes differing only in water/cement ratio and amount ofplasticiser. The research used two more methods based on the action of a thawing solution upon the surface of the specimen during freezing and thawing. These methods only differ in the direction in which the thawing agent acts on the test surface. The assumption prior to performing the experiments was that there is a strong dependence between the outcomes of the methods and the water/cement ratio value. The analyses performed have confirmed the pre-experiment assumptions to be correct.
