Abstract This research delves into the hydration processes and ecological repercussions of cement blended with papermaking sludge (PS) dyeing ash (DS). It targets alleviation detrimental environmental impacts from solid waste, alongside evaluating their prospective utilization in product fabrication. Low-temperature roasting DS is rich phosphates, which impose a hindering effect on initial clinker, displays superior pozzolanic activity when juxtaposed PS. Meanwhile, incorporation PS heightens malleability paste blend, consequently modulating pore size distribution within matrix, resulting amplified compressive resilience amalgamated samples. Additionally, inclusion presents an augmented surface area, promoting nucleation by-products. The infusion greater quantity by-products mixed matrix fosters refinement advances strength development. Furthermore, proficiently constrains heavy metals inherent curtails implications during compared conventional Portland cement, ternary employs un-calcined low-temperature activation DS. approach facilitates enhanced carbonation CO 2 sequestration industrial waste streams, thereby achieving carbon reduction at source.
