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.
