The Challenge of Grinding Ternary Blends Containing Calcined Clays and Limestone

The inclusion of high specific surface materials such as calcined clays in cementitious systems enhances the hydration clinker products at very early ages, but it may also increase water demand; thus, pursuit a flowing concrete demand an dosage superplasticizers. grinding regime can have major influence on properties system and could help mitigate problem demand. This paper discusses impact alternatives for production binder consisting clinker, clay, limestone gypsum. Two main target will be discussed: (i) LC3, with formulation 50% 30% 15% 5% gypsum, co-ground all together, (ii) LC2, mineral addition 60% 35% ground separately further blended Portland cement 1:1 basis (mass). experimental program is carried out several stages: binder, pastes (iii) standard mortars, aids from family TEA are used to enhance grinding, their assessed.
