Role of Modifiers on the Properties of One-Part Alkali-Activated Rapid Hardening Repair Mortar

Suat Çalbıyık, Nihat Kabay, Tarik Omur, Hakan Özkan

Rapid-repair mortars require high early-age strength, dimensional stability, and reliable substrate bond simultaneously, yet conventional alkali-activated materials (AAMs) have only partially met these requirements, and AAM feedstock base itself is contracting as blast furnace slag and fly ash availability declines under steel …

Valorization of waste concrete powder as a sustainable substitute for limestone fines in conventional concrete: a case study from Portugal

Hakan Özkan

The valorization of industrial by-products in cementitious materials offers a viable pathway for reducing the environmental impact of concrete production. Limestone fines (LF) are commonly used as a filler or a cement replacement material in concrete; however, alternative recycled materials that support …

Assessment of a novel rapid-hardening mortar incorporating waste basic oxygen furnace slag: mechanical behavior, durability, and environmental impact

Tarik Omur, Nausad Miyan, Hakan Özkan, Nihat Kabay

This study investigates the potential of alkali-activated rapid-hardening mortars (RHMs) utilizing basic oxygen furnace slag (BOFS) and ground granulated blast furnace slag (GBS) as precursors. BOFS enhances early-age strength, with compressive strength increasing from 3.3 MPa to 5.8 MPa at 3h and …
