Low-Clinker Cements with Low Water Demand
Reduction of water demand of cement pastes results in the decrease of the cement matrix porosity and, accordingly, in the increase of its strength and durability. The fluidity increase of the paste based on low-clinker binders with low water demand is one of the main problems in the production of cement composites with high strength and durability. This paper proposes a comprehensive approach to significantly reduce the water demand of low-clinker binders by using multicomponent supplementary cementitious materials of different origins as well as different methods of superplasticizer addition. Experimental studies determined practical possibilities of enhancing the superplasticizer effect in a wide range of low-clinker binders and combinations of supplementary cementitious materials (SCMs). Experimental results can be used to extend the classification of rheologically active SCMs for low-clinker binders.
