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

Advances 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.

Investigation of the Natural Pozzolans for Usage in Cement Industry

Procedia Technology, 2015
AbstractOne of the most important aspect of selecting the proper natural pozzolanic material as admixture of Portland cement in concrete or mortars is the chemical reactivity and mineralogical content. If the chemical reactivity index and quartz content are high the pozzolans can substitute the cement from the binder groundmass in a greater proportion.
