• Abstract:
  PROBLEM: Many entities currently use fly ash, slag, and other supplementary cementitious materials (SCMs) in Portland cement concrete (PCC) pavement and structures. Although the body of knowledge is limited, several states are currently using ternary cementitious combinations for structures and pavements. Increased use of SCMs will not only reduce the cost of PCC pavement and structures, it will also reduce the carbon footprint by utilizing byproducts of other industries. This project will investigate the use of potential ternary mixtures incorporating various combinations and replacement levels of SCM and their respective performance. From information cited by the American Concrete Institute (ACI) and others, there is general agreement that the use of SCMs is associated with these effects on concrete: improved workability and finish ability, strength gain, decreased temperature rise in mass concrete, reduced permeability in mature concrete, improved resistance to sulfate and chloride attack, increased freeze thaw resistance, increased modulus of elasticity, resistance to de-icing salts, resistance to corrosion of reinforcing steel, increased time of setting, and unpredictable change in time between initial and final set. OBJECTIVES: The objectives of this research are to characterize the fresh and hardened concrete characteristics of possible ternary combinations. From these results, ternary combinations can be specified and applications can be developed.
