The present research is conducted to optimize and introduce the sustainable and cost-effective hybrid ECC mixtures. The availability, expensive nature, and high carbon footprints of standard ECC constituents: silica sand (SS) and polyvinyl alcohol fiber (PVA) restricted its wide application. The designed hybrid ECC were prepared with three different profiles of fibers: PVA, PET and MSE. This study also investigates the usability of stone processing waste (SPW) in ECC. To analyse the effect of SPW on the robustness of hybrid ECC, six different ECC mixtures were prepared having SPW up to 100% as a substitute for SS. To check the role of various constituents in designed matrices compressive response, tensile performance, flexural characteristics, air permeability, electrical resistivity, sorptivity, environmental, economic performance, effect of chemical immersion were firmly recorded. Evaluated viability of hybrid ECC mixes depicted that strength, durability, strain, and ecological parameters improved appreciably. Thus, it was revealed that the incorporation SPW improved the robustness behaviour of designed ECC mixes. Economic index of developed mixes revealed that the cost of hybrid ECC mixes lowered by 43.3% as compared to fully PVA and SS containing mixes. In addition, developed hybrid ECC mixes improved sustainability by reducing carbon footprints which is beneficial for eco-friendly environment.

目前的研究旨在优化和引入可持续且具有成本效益的混合 ECC 混合物。标准 ECC 成分硅砂 (SS) 和聚乙烯醇纤维 (PVA) 的可用性、昂贵性和高碳足迹限制了其广泛应用。设计的混合 ECC 采用三种不同的纤维制备：PVA、PET 和 MSE。本研究还调查了石材加工废料 (SPW) 在 ECC 中的可用性。为了分析 SPW 对混合 ECC 鲁棒性的影响，制备了六种不同的 ECC 混合物，其中 SPW 高达 100%，作为 SS 的替代品。为了检查设计基质中各种成分的作用，牢固地记录了压缩响应、拉伸性能、弯曲特性、透气性、电阻率、吸着性、环境、经济性能、化学浸泡的效果。混合 ECC 混合物的可行性评估表明其强度、耐久性、应变和生态参数显着改善。因此，结果表明，SPW 的加入提高了设计的 ECC 混合物的鲁棒性行为。开发的混合物的经济指数显示，与完全含有 PVA 和 SS 的混合物相比，混合 ECC 混合物的成本降低了 43.3%。此外，开发的混合ECC混合物通过减少碳足迹提高了可持续性，这有利于生态环境。
