Abstract

This This study assesses the influence of the ternary cements composition containing waste materials on its rheological and hydration properties. As raw materials, Portland cement, phosphogypsum, and wastes of marble, clay brick, and clay tile were used. The raw materials specific area is the main factor that governs the pastes rheological behavior. Its increase implies a reduction of the yield stress and plastic viscosity. The variation of the ceramic waste/marble waste ratio changes the hydration kinetics in the first 48 hours. The pastes are mainly composed of C-S-H, portlandite, and ettringite. Ceramic, marble, and phosphogypsum wastes can be used as alternatives to natural raw materials in the production of ternary cements.
