Performance of Concrete Using Water Hyacinth Ash as a Partial Cement Substitute

open access: yesAdvances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Concrete is one of the most widely used construction materials, with cement as its primary component. However, cement production significantly contributes to CO2 emissions, posing environmental challenges. This study investigates the use of water hyacinth ash (WHA) as a sustainable partial replacement for cement in C‐30 grade concrete.
