From eruption to construction - Part B: Investigating the feasibility of volcanic material as partial replacement for cement in concrete
This study investigates to what extent supplementary cementitious materials, (SCMs) of volcanic material (VM) together with limestone (LS) can replace ordinary Portland cement, (OPC) in concrete through an experimental study. The study is done in collaboration with a partner group named Part A. They...

This study investigates to what extent supplementary cementitious materials, (SCMs) of volcanic material (VM) together with limestone (LS) can replace ordinary Portland cement, (OPC) in concrete through an experimental study. The study is done in collaboration with a partner group named Part A. They are conducting a similar study in which part SCM is replaced only with VM. The project is thus divided into two parts, with this study being part B. Nine mortar mixtures were tested for compressive strength, with an accompanying X-ray diffraction (XRD) analysis of pastes, to assess chemical properties over time. Out of the nine mixtures, one contains 100% OPC and is referred to as the reference mix (REF). Additionally, there are four mixtures with varying proportions of VM and LS, and four filler mixtures with corresponding amounts of filler to the VM-LS mixtures.
