Experimental Study on C60 High Performance Concrete with High Content Mineral Additives and Low Shrinkage Creep

Abstract:

Shrinkage and creep behavior of concrete are keys that affect bridge construction and usage. The C60 high performance concrete was prepared by adding high content mineral additives and reducing water-binder ratio. This kind of concrete has good work performance and higher pumpability. It also has a low shrinkage and creep feature. Experiments were carried out to compare performance to concrete without mineral additives. Results show that its shrinkage and creep value decrease about 30% to 50% within long age of 360 days.
