The interaction of microencapsulated phase change materials (PCMs) with polymeric chemical additives in an air lime binding matrix was studied. These polymer-based included adhesion booster (derived from starch) and a superplasticizer (polycarboxylate ether). Two different PCMs melting points 18 °C 24 were assayed. microcapsules composed melamine, paraffin-based PCM cores. Measurements zeta potential, particle size distribution, adsorption isotherms, viscosity analyses performed to comprehend the behavior within their compatibility PCMs. Zeta potential experiments pointed absence strong between particles At alkaline pH mortar, negative charge resulting deprotonation melamine shell shielded by cations, yielding high positive values stable dispersions polycarboxylate ether demonstrated ability counteract increase mixing water demand caused addition matrix. dispersing action on seen exert collateral dispersion Conversely, despite starch-based additive resulted formation large PCM-lime clumps. Air renders incorporating 5, 10, 20% weight various dosages these experimented until optimal formulation for specific application mortars as renderings achieved. This fine-tuned effectively tackled issues commonly associated mortars, such poor adhesion, crack formation, reduced fluidity.

Heritage structures built in the 19th and 20th centuries western part of Romania are marked by significant aesthetic influence Austro-Hungarian empire, with highly decorated façades facing street rather more simple surfaces towards back inner courtyard. This region is also shallow earthquakes, which significantly affect structural integrity these buildings. Considering current climatic context, energy efficiency regulations that apply to refurbishment heritage structures, additional need private owners authorities reduce seismic vulnerability it necessary develop integrated solutions could improve thermal performance building strengthen its load-bearing structure, while preserving valuable features visible from street. Therefore, this study intended investigate viability using different rehabilitation materials suitable for architectural characteristics buildings, integrating strengthening solutions. These applied a 19th-century comprises all specific found Romania. It compares effectiveness mineral-based insulation materials, cork lime-based plasters, aerogel–lime-based plaster or outer parts wall, depending on solution. solution problem will combine wet, techniques can be used exterior walls without affecting value building. In way, through analysed results, provides insights concerning potential increase sustainability masonry

Rammed earth blocks have recently gained substantial popularity in construction materials due to their environmental benefits, energy saving, and financial effectiveness. These benefits are even more pronounced if waste such as olive ash (OWA) incorporated rammed blocks. There is limited information on the use of OWA This paper investigates cement improving block characteristics. was partially replace soil by 10, 20, 30 40% its weight added percentages 2, 4, 6 8% dry composite soil. Proctor, unconfined compressive strength (UCS), California Bearing Ratio (CBR) tests were performed at 7, 28, 56 days. Results indicated that inclusion decreased maximum density while it increased optimum moisture content. However, addition improved The UCS results revealed possessed cementitious pozzolanic behavior, mechanical properties up 30% inclusion, after which there a significant drop 40%. trend CBR similar those UCS. To further clarify experimental results, mathematical model proposed determine variation function time. Furthermore, correlations between conducted. Predicted equations developed block.
