In mass concrete casting applications/structures, the heat evolved during the hydration process at early ages may not dissipate appropriately due to the large size of the pours and the low thermal conductivity of concrete. Embedded pipe cooling syste

There is a frequent need to take measures for temperature control in massive concrete structures, as to avoid thermal cracking risk at early ages (induced by temperature gradients inherent to hydration heat release). This research work has explored a

This study proposes a new methodology for the embedment of flexible PVC hoses (with the shape/geometry of the intended cooling pipes) that allows their removal a few hours after casting (i.e. after setting), while allowing that water is pumped throug

Energy consumption in buildings accounts for over 30% of the total energy use in the world, so it is a priority in the EU. Phase change materials (PCMs) can assist for thermal regulation, because they can save and release the heat. In smart buildings

Geopolymeric binders are especially indicated when reusing a wide diversity of wastes. This is an important feature, especially in the European context, in which a circular economy and future zero waste is targeted. Still, the cost of these materials
