Abstract:

The mechanical properties of PHC pile concrete with different mineral admixture (fly ashground slagground silica sand) were tested and interface microstructure of the concrete were analyzed by ESEM.The result show that,the compressive strength of PHC pile concrete with 20% ground silica sand or with 30% ground slag can reach more than 80MPa after autoclaved curing;The PHC pile concrete with 20% ground silica sand show the best mechanical properties.The tobermorite C₅S₆H₅ can be observed in ESEM photograph of interface of autoclaved curing concrete.
