FIELD: testing properties of materials and articles in production of concrete and reinforced concrete articles. SUBSTANCE: in agreement with process water is passed through tested sample, amount of absorbed water is measured continuously during conductance of experiment, graphical dependence of amount of water coming into sample on time is determined, points of inflection are isolated on graph, duration of water feed from start of experiment to second point of inflection is found and water IMPENETRABILITY is evaluated by relation B= 0.092B = 0,092tau, where B is water IMPENETRABILITY; tau is duration of water feed. Obtained value is rounded off to nearest minimum value multiple of two. EFFECT: improved reliability of process. 2 dwgd
