Abstract: Physical processes of developing high performance concrete (HPC) composites, such as characterisation of ingredients, mixing method to manufacture fresh concrete mix, transportation, placement and compaction are expected to have significant effects on the durability of HPC composites. This paper deals with the influence of mixing methods on the durability of HPC composites. Tests were carried out on a number of HPC mixes produced by different mixing methods to examine their influence on the RCPT value, pH and alkalinity of the mixes. It was observed that mixing method has significant influence on the RCPT value at 28 days and also on 28 days compressive strength, initial slump and slump retention. The effect of mixing method on the pH values and alkalinity at 28 days is not as significant as that on RCPT values.
