The viability of using vegetable Ampelodesmos Mauritanicus (Diss) fibers to develop lightweight construction material was investigated in this paper. The objective of this work is to assess the physico-mechanical properties of Diss fibers reinforced concrete sample with fibers to binder volume ratio ranged from 0 (control specimen) to 4. In order to mitigate the inhibitory effect exerted by vegetable materials on binder hydration, Diss fibers were treated with hot water, while air lime-based binder has been selected to replace traditionally used cementitious binder. The most important part of this work is focused on the efficiency of using air lime-based binder to develop lightweight construction material containing Diss fibers. Air lime-based binder is the chosen variety of binder due to its abundance and low emissions from its manufacture. The experimental investigation of the chemical compatibility between treated fibers and binder through the hydration-test has shown the effectiveness of boiling water treatment on the modifications of morphological and mineralogical properties to overcome the inhibitory effect exerted when non-treated Diss fibers were used. The hardened specimen properties included dry density, porosity, compressive and flexural strengths, and elastic behavior have been studied. The results have indicated that despite a reduction in compressive strength, the reinforced specimen remains acceptable to be used in lightweight construction applications, as regards its compressive strength-value and lightening level. The flexural strength of reinforced specimen was found to be significantly enhanced. Depending on the amount of Diss fibers used in the mixture, it was found that the optimal addition of Diss fibers is in the range of 3 volumes content. The corresponding flexural strengthening rate has reached a value of 86.5 % higher, due to the several reinforcement mechanisms like the compaction process, Diss fiber bond reinforcement, and also the undisturbed development of hydrate components of air lime-based binder during hardening. Therefore, the addition of Diss fibers generates failure mode change of specimen from the brittle to ductile behavior, which results in improvement of deflection and toughness capacity.

本文研究了使用植物 Ampelodesmos Mauritanicus (Diss) 纤维开发轻质建筑材料的可行性。这项工作的目的是评估 Diss 纤维增强混凝土样品的物理力学性能，纤维与粘合剂的体积比范围为 0（对照样品）至 4。为了减轻植物材料对粘合剂水化的抑制作用， Diss 纤维用热水处理，而空气石灰基粘合剂已被选择来代替传统使用的水泥粘合剂。这项工作最重要的部分是关注使用空气石灰基粘合剂开发含有 Diss 纤维的轻质建筑材料的效率。空气石灰基粘合剂因其丰富且制造过程中排放量低而成为首选的粘合剂品种。通过水合试验对处理过的纤维和粘合剂之间的化学相容性进行的实验研究表明，沸水处理对形态和矿物学性质的改变是有效的，以克服使用未经处理的 Diss 纤维时产生的抑制作用。已经研究了硬化试样的特性，包括干密度、孔隙率、压缩和弯曲强度以及弹性行为。结果表明，尽管抗压强度有所降低，但就其抗压强度值和轻量化水平而言，增强型试样在轻型结构应用中的使用仍然是可以接受的。发现增强试样的弯曲强度显着提高。根据混合物中使用的 Diss 纤维的量，发现Diss纤维的最佳添加量在3体积含量范围内。由于压实过程、Diss 纤维结合增强等多种增强机制，以及在硬化过程中空气石灰基粘合剂的水合物组分不受干扰地发展，相应的弯曲强化率达到了 86.5% 更高的值。因此，Diss 纤维的加入使试样的破坏模式从脆性转变为韧性行为，从而提高了挠度和韧性能力。以及在硬化过程中，空气石灰基粘合剂的水合物成分不受干扰地发展。因此，Diss 纤维的加入使试样的破坏模式从脆性转变为韧性行为，从而提高了挠度和韧性能力。以及在硬化过程中，空气石灰基粘合剂的水合物成分不受干扰地发展。因此，Diss 纤维的加入使试样的破坏模式从脆性转变为韧性行为，从而提高了挠度和韧性能力。
