Physical properties and structure of fresh cementitious pastes
Bleeding characteristics and rheological behavior of fresh pastes were studied to elucidate information on physical structure of pastes of pozzolanic and slag cements and mixes of lime with slag or pozzolana; trial cements were prepared in laboratory by mixing separately ground constituents homogeneously; pastes were mixed in Waring blender under vacuum; bleeding characteristics were measured using H.H.Steinour method; comparison of values of immobile water per unit volume of paste, and minimum water-cement ratio showed that cement replacements lowered degree of flocculation, strength of floc structure and porosity of sediment.
