摘要：
High strength high performance concrete (HPC) represents an important technological innovation which promises to unleash the full potential of the raw materials to produce an ecological concrete for the construction industry. This paper focusses on the chloride ion permeability of HPC mixes with strength greater than 75 N/mm(2). The influence of mineral and chemical admixtures on the strength development and chloride ion permeability of high strength HPC is also studied. The investigated mixes were proportioned with aggregates designed for maximum density, using packing density method. The results indicate that unique combinations of micro silica and superplasticiser exist for HPC mixes with negligible to very low chloride ion permeability. Equation for predicting 6 hour conductivity from 1 hour conductivity is also proposed.
