A main aspect of the geothermal well design is selection grouts backfilling space between a probe and surrounding ground, taking into consideration mineralogical, thermo–physical, mechanical flowability properties. The EU GEO4CIVHIC project aimed at developing efficient cost-effective systems suitable for air-conditioning refurbishment urban buildings. different was performed to ensure whole efficiency shallow heat exchangers designed within project. Experimental tests were executed identify...
Abstract Alkali-activated calcined clays are promising candidates for playing a prominent role in the future construction industry. These binders may achieve excellent mechanical performance, but one issue deserving attention is proneness to plastic shrinkage and surface cracking. Tackling this requires deployment of laboratory techniques that allow shrinkage-inducing mechanisms be quantitatively assessed. Here, we demonstrate time-lapse X-ray imaging can used quantify immediately after...
<p>The main goal of the EU funded GEO4CIVHIC project is development more efficient and low-cost geothermal systems for conditioning retrofitting civil historical buildings. In this framework, identification most appropriate grout different heat exchangers a key factor improving overall efficiency shallow systems. Therefore, dedicated investigation was focused on selection optimization thermo-physical properties grouting products to be used...
Investigating the microstructural development of cement-based materials is fundamental importance for establishing a link between micro-scale features and macroscopic properties. Conventional investigation by imaging methods based on optical electron microscopy has intrinsic limitations sample destructivity lack access to 3rd dimension. Such can be addressed use tomographic that allow 3D in-situ observation time-dependent properties hydrating cement. In this contribution, series CT-based...
<p>Ordinary cement resulting from the reaction of a calcium aluminosilicate-rich powder plus water works as binding matrix in modern concrete. The design alternative binders is currently global challenge order to reduce environmental footprint associated ordinary production. Alkali-activated calcined clay materials (AAccMs) represent class sustainable made blending concentrated alkaline solution and solid fraction with thermally treated phyllosilicates. Metakaolin produced by...
<p>In shallow geothermal systems, especially ground source heat pumps (GSHP), cementitious grouts play a decisive role in guaranteeing an efficient transfer between the probe and surrounding ground. Several studies have been devoted to understand effect of different additives (silica sand, graphite, fluorspar, glass fly ash …) improving thermal conductivity such mixtures, maintaining at same time physical properties as viscosity workability suitable for situ...
