• Abstract:
  The purpose of this study was to investigate the effect of cement paste quality on the concrete performance, particularly fresh properties, ; by changing the water-to-cementitious materials ratio (w/cm), type and dosage of supplementary cementitious materials (SCM), and airvoid ; system in binary and ternary mixtures. ; In this experimental program, a total matrix of 54 mixtures with w/cm of 0.40 and 0.45; target air content of 2%, 4%, and 8%; a fixed ; cementitious content of 600 pounds per cubic yard (pcy), and the incorporation of three types of SCMs at different dosages was ; prepared. The fine aggregate-to- total aggregate ratio was fixed at 0.42. Workability, rheology, air-void system, setting time, strength, ; Wenner Probe surface resistivity, and shrinkage were determined. ; The effects of paste variables on workability are more marked at the higher w/cm. The compressive strength is strongly influenced by ; the paste quality, dominated by w/cm and air content. Surface resistivity is improved by inclusion of Class F fly ash and slag cement, ; especially at later ages. Ternary mixtures performed in accordance with their ingredients. The data collected will be used to develop ; models that will be part of an innovative mix proportioning procedure.
