Between 1987 and 1990, selected elements from ten individual structures from within four facilities were examined to assess the long-term performance of concretes used. Structural members examined encompassed slabs on grade, suspended slabs and wharf elements. Individual concretes forming the selected structures had binders of normal portland cement, portland cement with fly ash or ternary systems of fly ash, ground granulated blast furnace slag and portland cement. Slag aggregates were used in certain of the concretes. Interest focused on the long-term in-service durability of the concretes. Conclusions were drawn with respect to the performance of the concretes.

This paper describes the development of high volume fly ash (HVFA) concrete for pavements. Concretes with fly ash content (40% and above by weight of the total binder fractions) were designed for structural grades. The workability, mechanical and long-term volume stability properties were evaluated. It was found that HVFA concrete with characteristic compressive strength up to 50 MPa could be designed having fresh concrete properties similar to plain cement concrete with the exception of setting times. For concretes of similar strength grades, it was found that the flexural strength and elastic modulus properties of HVFA concretes were similar to plain cement concretes. HVFA concretes were found to have a 15-20% lower drying shrinkage at 56 days than companion plain cement concretes. These reductions increased to 15-25% at 91 days. The setting times were increased by one to six hours depending on the type of cement and percentage of fly ash used. The concretes also developed considerable strength after 24 hours to withstand loading from normal construction activities. Trial production and placing of these concretes for apron slabs and road pavements was carried out at the Pacific Power's Mount River Piper Station. It ws found that HVFA concrete could be produced and placed successfully through normal concreting practices including pumping. Long term performance of these concretes are being monitored.
