The quality of the materials constituting masonry has a major influence on the type and seriousness of the damage that can occur due to salt crystallization. In the case of brick, the composition of the original clay, together with the production process, determine the quality of the final product and it's eventual susceptibility to salt decay....

During the past decade, several cases of damage of concrete structures due to alkali-silica reaction, ASR, have been diagnosed, detected, reported or published in The Netherlands [Heijnen and Larbi, 1999]. The structures involved include bridges, locks, balconies and viaducts (see Figure 1). This called for a critical review of the existing...

In the current Dutch standard NEN 5905 and CUR Recommendation 38, four methods are listed for assessing the alkali-silica reactivity of concrete aggregates. However, procedures outlining how the tests should be performed, and the possible errors associated with such tests, are not given. This makes interpretation of results obtained by any of...

This paper deals with a preliminary laboratory study to assess the effectiveness of thermal treatment methods to improve the quality of recycled concrete aggregate. The samples used for the study consisted of sieved fractions of crushed concrete that were subjected to various thermal treatments at temperatures of either 650 °C or 800 °C. In each...

The National Monument in Amsterdam (1954-'56), built as a memorial to the fallen of World War II, was restored in 1997-'98. The main material used was travertine from Tuscany (Italy), both employed for cladding the 20-m high pylon, constituting the soul of the monument, and the relieves and free standing statues connected to it. The intemal...

The Dutch National Monument in Amsterdam, a World War-II memorial structure, was built with an outer face consisting of slabs of travertine. In 1995, the masonry structure forming the core of the monument showed severe deterioration. In order to determine the actual cause of deterioration and to advise on the most suitable method of restoration,...

The term coating is used to denote a thin synthetic or polymer-based material that is applied to the surface of concrete in order to protect it from damage. In addition to good compatibility and bonding to substrates and adequate crack-bridging ability, coatings are designed to be durable in the environment in which they are applied. Yet, very...
