A persistent rise in the costs of construction materials has led to the need to address this problem in line with the Sustainable Development Goals. This research employed vegetal soft and rigid fibers in a screed mortar to produce a sustainable fabric-cement matrix. Four different vegetal-dried fibers (hemp, flax, miscanthus, and bamboo) with dosages of 0.4, 0.6, 0.8, 1.2, 2, and 4 kg/m were used. Laboratory investigations were slump test, bulk density, air occluded, shrinkage, and mechanical strength. Scanning Electron Microscope (SEM) assessments were performed and analyzed on the natural fibers and the screed formulation. The results highlight that fiber dosages significantly influence the above-mentioned properties.
建筑材料成本的持续上涨促使人们需要根据可持续发展目标来解决这一问题。本研究在找平砂浆中使用植物软纤维和硬纤维，以生产可持续的织物 - 水泥基体。使用了四种不同的植物干纤维（大麻、亚麻、芒草和竹子），用量分别为0.4、0.6、0.8、1.2、2和4千克/立方米。实验室测试包括坍落度试验、堆积密度、含气量、收缩率和机械强度。对天然纤维和平整砂浆配方进行了扫描电子显微镜（SEM）评估和分析。结果表明，纤维用量对上述性能有显著影响。
