During the process of cutting andesite stones, the waste mud is kept in powder form once fully dried. It is difficult to store the waste that is produced as a consequence of the extensive utilization area and consumption of andesite. Thus, eliminating waste storage challenges and incorporating these wastes into the economy are crucial. For this reason, this study examined the effects of waste andesite dust (WAD) on the flexural behavior of reinforced-concrete beams (RCBs) using experimental testing and 3D finite-element modeling (FEM) via ANSYS. Thus, different rates of WAD up to 40% were used to investigate the influence of the WAD rate on the fracture and bending behavior of RCBs. While the RCB with 10% WAD had a slightly lower load-bearing and ductility capacities, ductility capacities significantly drop after 10% WAD. At 40% WAD, both the load-bearing capacity and ductility significantly reduced. Based on the experimental findings, using 10% WAD as a replacement for cement is a reasonable choice to obtain eco-friendly concrete. Moreover, the outcomes of 3D FEM were also compared with those of experiments conducted using ANSYS v19 software. The displacement values between the test and FEM findings are quite similar.
在切割安山岩石材的过程中，废泥浆完全干燥后会保持粉末状。由于安山岩的广泛使用面积和消耗量，所产生的废料难以储存。因此，消除废物储存挑战并将这些废物纳入经济体系至关重要。出于这个原因，本研究通过实验测试和ANSYS三维有限元建模（FEM），研究了废安山岩粉尘（WAD）对钢筋混凝土梁（RCB）弯曲性能的影响。因此，使用高达40%的不同比例WAD来研究WAD比例对RCB断裂和弯曲行为的影响。虽然含10%WAD的RCB的承载能力和延性能力略低，但在WAD含量超过10%后，延性能力显著下降。在WAD含量为40%时，承载能力和延性均显著降低。基于实验结果，使用10%的WAD替代水泥是获得环保混凝土的合理选择。此外，还将三维有限元分析的结果与使用ANSYS v19软件进行的实验结果进行了比较。试验结果和有限元分析结果之间的位移值非常相似。
