When crushed lightweight aggregates are used in lightweight aggregate concretes very small water amounts evaporate from the concrete even in a dry environment. It is shown that a large portion of the free batch water is absorbed into the pore structure of the crushed aggregates. The relative ...
The results indicate that both LECA aggregate size and its percentage and the cement content have significant effects on the properties of lightweight concrete. A critical finding of the study is related to the tensile strength (ft) of LWAC, which was shown to be overestimated if determined ...

The density of the isopods was not uni- form in the ponds: they were found in greater con- centration near the sides close to the concrete wall. Stomach dissection of isopods showed presence in abundance of holothurian spicules. Symptoms of diseased juveniles (n = 189) placed in ponds ...
aDespite the increased use of stainless steel for concrete reinforcement in harsh chloride environments, comparatively little is known about the surface chemistry of these materials in alkaline media simulating concrete pore solutions. This work is concerned with a combined electrochemical and XPS surface...
