Flexural and Crack Behaviors of RC Beams Applied with UHTCC Cover Subjected to Rebar Corrosion Xinhua Cai 1,a, Shilang Xu 2,b, Zhen He1,c 1State Key Laboratory of Water Resouses & Hydropower Engineering Science, Wuhan University, Wuhan 430072 2College of Civil Engineering & Architecture, Zhejiang University, Hangzhou 310058 aemail: caixinhua_whu@yahoo.com.cn, bemail: slxu@zju.edu.cn, cemail: evahezhen@126.com Keywords: ultra high toughness; corrosion of reinforcing bar; corrosion expansive cracking; strain hardening; multiple cracking Abstract.
Prolonging occurrence time of rebar corrosion in reinforced concrete structures could be achieved by increasing the thickness of cover, decreasing the ratio of water and cement materials, applying the polymer concrete or mortar, epoxy-resin coating bars or adding anti-corrosion admixture[2].

Since the thermal conductivity is low, this method is not suitable for high-power LED drivers; b) encapsulating thermal conductive materials for the interior of the drivers' power supply.
The shrinkage of thermal conductive materials will produce stress to the pins of electric components, and the power supply is non-repairable once damaged.
