Zhou Fenghua;Yang Haitao;Tianjin Construction Engineering Quality and Safety Regulatory corps;China Construction Ready Mixed Concrete TianJin CO., Ltd.;
The design strength grade and impermeability grade of raft concrete is C50 and P8. By determing the reasonable dosage of admixture and strength of concrete as well as the durability requirements the study established mix evaluable system of C50P8 large volume concrete. The design can meet the requirement of raft concrete on the requirement of long life design and huge volume.
