Concrete containing ternary blended binders: Resistance to chloride ingress and carbonation
This study examined the chloride and carbonation durability performance of concrete containing ternary blended binders in comparison to PC (Portland cement) and binary PC/PFA (pulverized-fuel ash) concrete of equivalent standard 28 day cube strengths of 20 N/mm2, 40 N/mm2 and 60 N/mm2. In addition, the nature of the near surface pore structure of the concrete has been inferred from its initial surface absorption. It has been shown that the chloride resistance of all the TBC (ternary binder concrete) is significantly higher than corresponding PC and PC/PFA mixes. On the other hand, however, under worst case conditions it was found that after 30 weeks accelerated exposure, carbonation depths were generally greater in the TBC mixes. The degree to which this occured was found to relate to the amount of PC replaced.
