水泥基材料水分传输研究与进展综述

Water transport through cement-based materials results in chemical and physical responses in the materials, which is one of the main factors leading to the problems of durability of concrete structures, therefore, it is greatly important for the research on water transport and how to measure and evaluate the transport properties reasonably. The paper gives a review on the newly research of water mass transport in cement based materials. Based on the transport mechanism, the conception of saturated and unsaturated water transport was distinguished, and the measurements and evaluation criterion were introduced respectively. The review of the research of the mostly used saturated permeability is given, and the importance of the unsaturated water transport, which really happens in field structures, is also indicated.
