This study focuses on developing a cost-efficient engineered cementitious composite
(ECC) with glass and polypropylene fibers, using local materials for sustainable construction in developing countries. The ECC exhibits unique properties such as strain hardening, enhancing structural resilience and crack mitigation. The composite utilizes a 1–2% volume of 6 mm fibers, with fly ash as a supplementary cementitious material and a superplasticizer. PPGF-ECC surpasses PC in mechanical properties, making it suitable for various applications, including rigid pavements in developing countries. This research recommends 2% PPGF-ECC for various applications in developing countries, including rigid pavements, due to their superior performance.
