The main role of silica-Based cement free binders on the microstructural evolution and mechanical behaviour of high alumina castables

摘要

One of the major innovations for monolithic refractories in the past decade has been the development of cement free binders, no-cement castables (NCCs). NCCs with colloidal silica suspensions as binders are extended at industrial scale. Microsilica-based powder binders are valuable alternative to colloidal silica to avoid installation and transport difficulties.
