Bonding Steel Plate To Concrete

Plate bonding is a well established process used to strengthen bridges and other structures originally using steel plates applied to plane concrete surfaces using epoxy resin adhesive and bolted fixings the plate bonding technique is used to provide additional resistance to bending improve load capacity or reduce deflections.

Bonding steel plate to concrete.

Most applications have been to increase flexural strength or stiffness by bonding plates to the soffits or top surfaces of beams and slabs. Guideline specification for external bonding of steel plates to concrete by injection of structural epoxy adhesives general. The injection resin shall be a two. It is this bond which is responsible for transfer to stresses from steel to concrete and thereby providing composite action of steel and concrete in r c c.

The term bond refers to the adhesion between concrete and steel which resist the slipping of steel bar from the concrete. Laboratory work consisted of testing 4 9 m and 3 5 m beams with steel plates bonded to their tension flanges in 4 point bending. Calder research into the technique of bonding steel reinforcement externally to hardened concrete is described. The contractor or his sub contractor subject to certain pre qualification conditions shall furnish all.

It has excellent anti aging shock resistance properties in self adhesion and mutual adhesion of steel and concrete with high shear rate used for seismic reinforcement of many buildings. Bonded steel plating for strengthening concrete structures m d. The bond develops due to setting of concrete on drying which results in gripping of the steel bars.
