Study on cracking control of high performance concrete at early age
It analyzed the reasons for the early cracks in high-performance concrete,and prepared overall program to improve the mechanical properties and the durability of the HPC.It studied on cracking control of HPC at early age and improvement of impermeability by mixing ratio test.The result showed that,it get better inhibition on the early cracks by reasonable adjustment to the water-binder ratio,fly ash and mineral fine powder dosage with saturated aggregates and the right amount of expansion agent,and it also provided high-performance concrete for different performance with a mixture ratio test methods.
