The properties of concrete materials determine the effect of building energy efficiency . article analysis of several new types of concrete technology configuration method , excellent potential , attribute and apply , also describes the development and promotion of these technologies , Hopefully new concrete technology can be widely applied to under construction .

with the development of our society and Economy , in the course of our country's road and bridge construction , Concrete technology has been greatly developed and applied . But traditional concrete construction technology there are a lot of problems in the construction of municipal road and bridge in our country. ,,resulting in the construction of the bridge there are _ Issues , affects Public security _ . accordingly requires Effective analysis and discussion of existing problems in traditional concrete technology , and some improvements to traditional concrete technology , So that it can be better in the construction of municipal Road and bridge can be effectively implemented and applied .

 in the construction of the industrial and civil works , Steel member stiffness is low , Low Concrete strength , The problem of poor concrete cracking is more frequent . Pre-stressed concrete technology appear , The provides a good technical condition to further reduce the occurrence of the above problems . This article mainly from the prestressed concrete structure overview As the starting point , Combining Project Cases Analyzing concrete application of prestressed concrete technology in engineering projects , discusses the phase off protect and monitor , In order to improve the overall quality of the project to provide some the Reference and comments .
