oa Civil Engineering = Siviele Ingenieurswese - Some aspects of prestressed concrete with particular reference to electrical transmission structures



The case for using prestressed reinforced concrete in the design of electric transmission masts and traction supporting structures is presented. A study is made of the component materials and emphasis is laid on the importance of the original water/cement ratio of the concrete used. Partly from theoretical considerations, but mainly from empirical data it is shown that only concrete obtained from a paste free from capillary water can eliminate the danger of the steel reinforcement corroding within the structure.
