Abstract In the present experimental/numerical study, a combination of ceramic waste and ground-granulated blast furnace slag were used in the preparation of one-part alkali-activated binders. Moreover, the effect of fiber type and content on hardened-state properties and shrinkage was studied under two different curing conditions. In the first stage of this study water absorption, compressive strength, and flexural strength were assessed. Subsequently, the flexural performance of fiber-reinforced binders was simulated and predicted using finite element models under concentrated and distributed flexural loading, respectively. The experimental results showed that fibers improved mechanical properties, and enhancement was governed by fiber type and curing conditions. Moreover, the numerical results indicated that the developed fiber-reinforced binders offer a flexural load-carrying capacity in the range of 10–40 kN/m2 and permissible service loads were well below the ultimate capacity.

纤维增强的单组分碱活化矿渣/陶瓷粘合剂

摘要 在目前的实验/数值研究中，陶瓷废料和磨碎的高炉矿渣组合用于制备单组分碱活化粘合剂。此外，在两种不同的固化条件下研究了纤维类型和含量对硬化状态性能和收缩率的影响。在本研究的第一阶段，评估了吸水率、抗压强度和弯曲强度。随后，分别使用有限元模型在集中和分布弯曲载荷下模拟和预测了纤维增强粘合剂的弯曲性能。实验结果表明，纤维改善了机械性能，增强效果受纤维类型和固化条件的控制。而且，
