The impressed current technique was used for forcing corrosion of the rebar, which was embedded in concrete coupon, so that correlation could be drawn between microstructure and corrosion behavior in short duration. Corrosion susceptibility increased from force air-cooled–quenched–air cooled–furnace ...
采用热喷涂Zn金属涂层、 涂覆环氧树脂涂层和电沉积Zn/钝化等表面处理方式, 对混凝土内置钢筋进行处理, 通过电化学交流阻抗谱技术(EIS), 探讨处理后的钢筋在混凝土中的腐蚀行为, 并与未经防护的钢筋进行了比较。结果发现, 在混凝土包覆的条件下, 三种涂(镀)层对抑制混凝土内置钢筋的腐蚀均具有明显作用; 相比之下, ...

Foundations: Rebar is used to reinforce concrete foundations, providing the necessary tensile strength to support the structure. Beams and Columns: Rebar helps beams and columns withstand loads and resist cracking. Slabs: Rebar is embedded in concrete slabs to enhance their durability and load-bearing...
Qin et al. (2015) demonstrated the feasibility of using PZT material as an embedded corrosion sensor able to differentiate between stages of rebar corrosion during an accelerated corrosion test. Specifically, the PZT sensor embedded in concrete was designed to generate and receive ultrasonic waves, ...
Corrosion behavior of mild steel plain bar embedded in concrete with 28 days compressive strength of 40 N/mm 2 exposed to natural marine environment at a l... P Venkatesan,N Palaniswamy,K Rajagopal - 《Progress in Organic Coatings》 被引量: 70发表: 2006年 CORROSION OF REINFORCED CONCRETE ...
When reinforcing rebars are already embedded in concrete, to prevent spalling or cracking of concrete or destruction of the bond between the concrete and steel, allowances must be made for thermal expansion of the steel. Acceptable and unacceptable fillet and groove weld profiles are illustrated in...
Below, we look at some properties that make rebar an excellent choice for reinforcing concrete structures. 1. Expansion Once embedded in the concrete, rebar must have a thermal coefficient that is as closely identical to the concrete’s as possible. In other words, they must expand and contract...
The connection is 2 lengths of rebar embedded into the concrete T flange, then a vert. stainless steel plate is welded to the ends of the embedded rebars. The T's are erected in the field, then the stainless plates are connected by welding a piece of rebar inbetween them. There have ...
For structures that require flexural strength for resistance to bending moments, reinforcing steel--rebar--is embedded in the concrete. 对于结构来说,需要弯曲应力去抵抗弯矩,因此钢筋被嵌入到混凝土材料中。 zhidao.baidu.com 3. While other materials may have the strength, steel rebar has the ideal exp...
