Abstract

Usually, energy and structural improvements for historic masonry buildings are addressed separately using distinct methods and protocols. This paper covers an integrated assessment of new composite materials to reduce the seismic vulnerability of historic masonry buildings while complying with sustainable conservation requirements, emissions’ reduction, and energy savings. Firstly, this study focused on selecting suitable thermal mortars that could serve as the base material for the innovative composite. Subsequently, the mechanical characteristics of these mortars were examined by subjecting them to compressive and three-point bending tests. Dynamic thermo-hygrometric simulations were conducted using commercially available software to check the energy performance of the composite material when used on walls of existing masonry buildings. The thermal mortar that exhibited the most favorable mechanical and thermal properties was subsequently reinforced with a basalt fabric. A composite sample was assembled and subjected to direct tensile testing to determine its stress–strain behavior.

创新和可持续的复合材料，用于历史砖石建筑的抗震和能量升级

通常，历史砖石建筑的能源和结构改进是用不同的方法和协议分别解决的。本文介绍了一种新型复合材料的综合评估，以减少历史砖石建筑的地震脆弱性，同时符合可持续保护要求，减少排放和节约能源。首先，本研究重点选择合适的热砂浆作为创新复合材料的基础材料。随后，通过对这些砂浆进行压缩和三点弯曲试验来检查其力学特性。利用市售软件进行了动态热湿模拟，以检查复合材料在现有砖石建筑墙壁上使用时的能源性能。表现出最有利的机械和热性能的热砂浆随后用玄武岩织物加固。组装复合材料样品并进行直接拉伸测试以确定其应力-应变行为。

期刊介绍： Fibers (ISSN 2079-6439) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications on the materials science and all other empirical and theoretical studies of fibers, providing a forum for integrating fiber research across many disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. The following topics are relevant and within the scope of this journal: -textile fibers -natural fibers and biological microfibrils -metallic fibers -optic fibers -carbon fibers -silicon carbide fibers -fiberglass -mineral fibers -cellulose fibers -polymer fibers -microfibers, nanofibers and nanotubes -new processing methods for fibers -chemistry of fiber materials -physical properties of fibers -exposure to and toxicology of fibers -biokinetics of fibers -the diversity of fiber origins
