Experimental Study on Durability of Foundation Concrete of Transmission Lines in Golmud Area
Abstract:
Transmission lines pass through various types of regions in China and some of that are corrosive. The foundation concrete of transmission lines in corrosive environments had shown serious deterioration, which usually caused by concrete deterioration, rebar corrosion, degradation of bond strength between rebar and concrete due to various corrosive effects. There are salt lake areas in west China where some power transmission channels pass through. Field tests are carried out in Golmud area to research the durability of foundation concrete of transmission lines. And test results show that the concrete strength in the air is higher than underground and the carbonation depth of the foundation concrete decreases with the increase of concrete compressive strength.
