Influence of Environmental Humidity and Test Depth on the Measured Gas Permeability of Concrete

Article Preview

Abstract:

The durability of concrete depends on its ability to prevent the ingress of aggressive chemical species. Transport properties of concrete, mainly permeability, play a key role in assessing and predicting the durability of reinforced concrete structures. This paper presents an experimental study on gas permeability of concrete influenced by environmental humidity and test depth. Gas permeability of concrete were measured both under dry condition and air-water balance by Cembureau method. A fine linear relationship between gas permeability coefficient and porosity of concrete blocks is shown in this article.
