Betono gaminių užsipildymo vandeniu kinetika

Abstract

The decay of concrete ware in the explotation conditions caused by the main climatic factors, such as variations of temperature and humidity, wind, the intensity of sunbeams. Generally, they don't act individually but strengthen or reduce the influence of other factors. The humidity of the material has a big meaning for the durability of the concrete ware. The thermal conductivity, the deformations of swelling and contraction, mechanical effects of frozen and thawing water of concrete depend on humidity content. Water, like an agent, transports chemical and biological infections (chemical corrosion), melts down minerals and connects to new derivatives. Understanding the kinetics of concrete water absorption is specifically important choosing manufacture for works. Considering the kinetics machanism of concrete water absorption it is important to understand how water soaks to manufacture.
