Study on Coefficients of capillary flow by means of wet-cup method and inverse-wet-cup method

摘要

The experiment that covered three temperatures, (i.e. T = 20, 35 and 50 deg. C) and three cement mortars (w/c = 0.50; 0.65; 0.80) was aimed at the examination of capillary flow coefficients on the basis of stationary water transport processes. Measurements were arranged to allow for the separate testing of flow for samples With one end resting in the atmosphere of air humidity ψ ≈ 100/100 (Wet-Cup Method, coefficient D_k-WCM) and the samples with one end placed in the water (Inverse-Wet-Cup method, coefficient D_k-IWC).
