Influence of supplementary cementitious materials on factors controlling the fresh state of hydraulic binders

It is obvious that SCMs (supplementary cementitious materials) have diverse effects on the physical and chemical properties that can contribute in the development of the mechanical performance of cementitious materials. Moreover, the key factor to better use SCMs in blended cements is to control their fresh state properties. However, limited literature is available on the influence of SCMs on the rheological behavior of fresh pastes. In light of the increasing interest concerning the fresh state properties of hydraulic binders based SCMs, this contribution reports the rheological behavior of various hydraulic binders based GGBS (ground granulated blast-furnace slag), FA (fly ash), limestone or calcined clays, and explore the factors influencing the particle interactions during the structural build-up/breakdown process when stress is applied to the system.
