Influence of Mix Proportions on Water Absorption of RCA Concretes
Roman Jaskulski , Paweł Las , Wojciech Kubissa
AbstractThe subject of the work is to develop probabilistic models defining the water absorption of concretes made with the use of recycled aggregate (RCA). For the study 16 series of concrete mixtures were made with a 50 mass% share of recycled aggregate in the whole amount of coarse aggregate. The analysis of test results aimed at formulating a relationship between water absorption value and selected parameters of the composition of concretes. The objective was to find a model giving the best fit between calculated values and test results. Formulated models were then used in probabilistic modeling absorption using a Monte Carlo simulation. The results indicate a good agreement of the mean values of water absorption and possibility of good fitting of the standard deviation if an additional summand is introduced into the model.
