Hybrid alkaline cement is a new type of alternative material to Portland cement. This research work aims to optimise the properties of hybrid alkaline cement and apply it to pipe pile production. The hydration kinetics control and shrinkage behaviour under the steam curing conditions or high temperature sealed conditions are the focus. The setting time, hydration heat and reaction extent will be investigated and the hydration kinetics will be controlled by different activators. For shrinkage behaviour, the autogenous shrinkage, drying shrinkage and carbonation shrinkage of hybrid alkaline cement under different curing regimes will be learned, also the mitigation of shrinkage behaviour will be studied. Microanalysis and mineralogical analysis will be done by XRD, BSEM-EDX,FTIR and NMR. This work will provide fundamental knowledge about the hydration of hybrid alkaline cement and transfer technologies to industry.
