Abstract

This study assesses the mechanical properties of mortars incorporating waste paper sludge-derived cellulose fibers. Compression and flexural tests were carried out on specimens prepared with cellulose fibers at different proportions, ranging from 0% to 2% of the total weight of the solid mortar constituents (cement, sand, and lime). In addition, a comparative analysis was carried out to evaluate the influence of the preparation method on the mechanical properties of the mortars. To this end, two series of mortars were studied: one prepared following a rigorous control of the preparation parameters and the other made without systematic parameter control to simulate typical on-site conditions. Finally, the applicability of both traditional and eco-friendly mortars in the construction of small-scale masonry walls was assessed through compression tests. Overall, the mechanical properties of mortars with cellulose fibers were comparable to those with 0% waste material, regardless of the production process. Regarding the compressive behavior of masonry walls, experimental tests showed significant similarities between specimens made with traditional and eco-friendly mortar. In conclusion, incorporating cellulose fibers into cement-based mortar shows considerable potential for building applications, enhancing the environmental benefits without compromising the mechanical behavior.

含废纸污泥衍生纤维素纤维的水泥基砂浆在建筑中的应用

本研究评估了含有废纸污泥衍生纤维素纤维的砂浆的机械性能。研究人员对使用纤维素纤维制备的试样进行了压缩和弯曲试验，纤维素纤维的比例从固体砂浆成分（水泥、沙子和石灰）总重量的 0% 到 2% 不等。此外，还进行了对比分析，以评估制备方法对砂浆机械性能的影响。为此，研究了两个系列的砂浆：一个是严格控制制备参数后制备的砂浆，另一个是在没有系统参数控制的情况下模拟典型现场条件制备的砂浆。最后，通过压缩试验评估了传统砂浆和环保砂浆在小型砌体墙施工中的适用性。总体而言，无论生产工艺如何，含有纤维素纤维的砂浆的机械性能与不含废料的砂浆相当。关于砌体墙的抗压性能，实验测试表明，使用传统砂浆和环保砂浆制作的试样具有显著的相似性。总之，在水泥基砂浆中加入纤维素纤维显示出在建筑应用中的巨大潜力，在不影响机械性能的情况下提高了环境效益。

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
