Experimental determination of the influence of fresh concrete composition on its resistance to water and de-icing chemicals by means of two methods

Popis výsledku v původním jazyce

Concrete’s durability is currently a frequently discussed topic. The determination of concrete’s durability is rather difficult since it depends on a number of factors, out of which the surface-layer quality is very important. One of the options for assessing its quality is the determination of concrete’s resistance to water and de-icing chemicals. The testing is based on loading the concrete by cyclic freezing and thawing during the simultaneous action of a thawing solution. The damage to the surface layer manifests itself as scaling, i.e., the loss of small scales from the surface of the material. The resistance of concrete to water and de-icing chemicals can be determined by means of several methods; however, a universal method of evaluation has not yet been established in Europe. The goal of the experiment described here was to assess the influence of fresh concrete’s composition on its resistance to water and de-icing chemicals using two different measurement methods (method A and C). A total of 9 fresh concrete mixtures were designed, from which specimens were made. The experiment was created and evaluated using the statistical method DOE (Design of Experiment). Based on the tests performed, it can be stated that a change in the content of cement and plasticiser in fresh cocrete is visible in the results of both methods. However, more so in the results for method C, which is generally more sensitive to changes in fresh concrete’s composition.
