Performance evaluation of eco-friendly mortar made with natural and artificial pozzolans; red clay and glass powder.
الملخص
Abstract: To reduce the environmental impact associated with Portland cement (PC) manufacturing, the use of supplementary cementitious (pozzolanic materials) materials in the development of cement-based materials such as concrete and mortar, has gained great attention in recent years. For this reason, this research study investigates the effect of using two types of pozzolanic material (natural and industrial pozzolan), represented by red clay (RC) and glass powder (GP), as a partial substitution for Portland cement in the preparation of cement-based mortar. The methodology of this study involved the design of seven mortar mix compositions and evaluating them in terms of workability and unconfined compression strength (UCS). Accordingly, the results showed that the addition of glass powder as a cement substitution yielded a gradual workability improvement, whereas the incorporation of red clay as a cement substitution induces a gradual workability reduction. In contrast, the unconfined compression strength revealed that the optimum glass powder content for strength performance was 5%, whereas no strength improvement was observed in this study using red clay, thus indicating the superiority of glass powder in enhancing the mechanical properties of mortar. Therefore, the outcome of this study suggests the possibility of improving both the fresh and hardened mortar properties using glass powder, as a partial replacement for cement.
