This paper comprises an overview of the results of a research programme to determine the properties of concrete made with ternary metakaolin (MK) – Pulverised fuel ash (PFA) – Portland cement (PC) binders. The properties are compared and contrasted with those of equivalent concrete made with binary MK-PC and PFA-PC binders and PC binder. A range of water to binder ratios were employed (0.4, 0.5, 0.6) and the properties monitored were workability, compressive strength development, sorptivity, carbonation, and chloride ingress. The data are complemented by measurements of temperature rise and sulphate resistance of mortars made with the ternary and binary binders, and thermogravimetric analysis of pastes made from the same binders. The results establish that improved performance can be achieved by using particular combinations of the different binders.
