Applications of High Performance Concrete (HPC) in Various Concrete Structures and Providing Appropriate Construction Procedures in Iran

Considering Continuous and fast changes in technology , Concrete technology is not an exception , as the result , it is developing and chainging rapidly . Due to extensive application of various special concrete in the current construction in all over the world and with respect to rapid application of High Performance Concrete (HPC) including : using HPC in structures exposed to weather or other severe exposure conditions such as : parts , concrete perfabricated panels , bridges and etc . Awareness of the technology related to the mentioned concretes shoud be considered more in Iran . In this paper the application of HPC in different countries and also the advantages of various types of HPC in different kinds of projects have been investigated . Due to low application of HPC and because it is not a convenial technology in Iran , first , the Special Concrete useage in Iran investigated and also the HPC application cases provided . Due to application of HPC in different concrete structures in the worlds , this paper in three general sections attempts to focus on the project carried out in the world , including : 1-HPC bridges , 2-Concrete buildings and parkings made of HPC , 3-Special structures made of HPC , Afterwards construction feasibility and application of characteristics of introdused concretes in the similar structures used in all over the world discussed and for each structures , a certain special concrete with a mix design and the conditions and procedure of construction , considered .
