Вплив м’яких режимів теплової обробки на водопоглинання бетону

Abstract

Heat treatment on water absorption of concrete slabs of concrete paving and concrete cubes was performed using low-potential heat sources - air heated in the solar energy collector and the heat of cement hydration. It is indicated that the presence of concrete cubes in the chamber is conditioned by the requirements of the standards for determining the properties of concrete. The water absorption of concrete cubes was determined, the hardening of which occurred with the use of heat treatment and without heat treatment. The water absorption (not standardized) of concrete tiles, hardening of which occurred with the use of heat treatment and without heat treatment, was determined. It is indicated that since the water absorption rates of concrete tiles are not standardized, they can only be used for comparison with concrete tiles. It has been established that the thermal treatment of water absorption tiles of concrete pavement and water absorption of concrete cube does not lead to an increase in the open porosity of the concrete.
