Some fundamental challenges are shaping the world we live in, and the need for alternative materials and energies is one of the most prominent issues of this century, especially in the light of global warming and energy need. Another crucial point concerns ...
Energy geostructures represent a renewable and clean source of energy which can be used for heating and cooling of buildings and de-icing of infrastructures. This technology couples the structural role of geostructures with the energy supply, using the pri ...
Alkali-Silica Reaction (ASR) is a deleterious expansion phenomenon which affects the long-term behaviour of concrete. Its origin is a chemical reaction between amorphous silica present in the aggregates and alkali ions from the concrete pore solution. The ...
There is currently a lack of established calculation method for the geotechnical design of heat exchanger piles, although the technology is experiencing a fast expansion. Instead of quantifying the effects of temperature changes on the static behavior of h ...
Modelling transport and long-term creep in concrete materials is a difficult problem when the complexity of the microstructure is taken into account, because it is hard to predict instantaneous elastic responses. In this work, several numerical methods are ...
A simplified method of measuring concrete resistivity, as an index of permeability, has been developed that is similar to ASTM C1202 or the rapid chloride permeability test (RCPT). It is significantly faster and easier to perform, however In this test, cyl ...
A reinforcing element (10) for structural concrete construction comprising a rod- shaped bar (1 1 ) having a cross-sectional enlargement on at least one end thereof. The rod shaped member (11 ) comprises an elbow portion (12) on said at least one end being ...
Hybrid slab systems combining fiber-reinforced polymer (FRP) composites with concrete are promising load-bearing structures, and an increasing number of applications has demonstrated their high potential in terms of structural performance and durability. H ...
As part of a 15-year railway noise remediation plan, 300km of noise barriers will be installed in Switzerland over the next few years. To enable pultruded glass fiber- reinforced polymer (GFRP) materials to be used for the noise barrier posts, a specificat ...
The mechanisms that contribute to early-age cracking are complex. Determining the relative importance of each mechanism as well as the combined cracking potential for a given concrete material is essential for the concrete industry to construct structures ...
