New Corrosion Resistance Bar in Sandwich Wall

Sandwich masonry wall is an energy-saving composite wall with good mechanical properties and durability. But the adhesion strength to its tie bar affects its permanence. In order to simple the traditional production processes, a new method was proposed. First, a new theory of anti-corrosion using amino and carboxyl groups to change the distribution of steel surface was introduced. The theory was used to produce a high strength environmentally friendly steel agent layer which can guarantee the durability of the entire wall. The high strength materials can reduce the weight of whole walls with low cost. In order to meet the strength and the stiffness requirements, the appropriate tie bars were selected by the experimental analysis. The results show that the new method can overcome the bond strength of the issue. It has a high performance, good insulation, and good corrosion resistance. It effectively prevents the corrosion of steel. The is a simple and effective approach for the harbor construction and maintenance, bridge construction and maintenance, public works, infrastructure construction, temporary buildings, and so on.
