Bonding Strength

Reasons for decrease in the Bonding Strength:

Corrosion is a major problem in steel. Formation of rust on structural steel decreases its life, after reinforcing it with concrete mixture. It is an established fact that corrosion is the deadliest enemy of any reinforced structure. Moisture, seepage / ingress of water causes frequent corrosion on steel. Structural cracks are observed, which is an indication that the bonding of steel with concrete has been weakened / separated due to creation of rust and these are subject to normal conditions all TMT bars.

Reasons for the Increase in Bonding Strength after applying “Steel Guard Nanocoat TM”

The Test reports conducted by M/S Structural Designers and Consultants Pvt. Ltd. Mumbai, TISCO, Jamshedpur and ELCA Laboratories, Mumbai are to be referred here.

TMT bars treated with “Steel Guard Nanocoat TM” are free from corrosion. “Steel Guard Nanocoat TM” is a revolutionary invention based on Nanotechnology (Micro Crystal Development Technology) wherein it works at the molecular level by penetrating inside the pores of the surface. It creates a Dense Crystal Formation (Frost) protective layer consisting of millions of nuclei. This layer acts as a barrier between the applied surface and atmosphere stopping the formation of Fe2 & Fe3 ions, which are the main agents of corrosion. The Crystal layer thus formed is so closely interlinked & interwoven that it does not allow water & gas to penetrate inside. This phenomenon prevents corrosion and ultimate result in an increase in the bonding strength of steel with concrete. The detailed reasons for are mentioned below:

  • When Steel Guard comes in close contact with steel, it starts reacting with Fe2 and Fe3 ions and bond them in such a way that further conversion of Fe2 & Fe3 ions into hydroxy carbonates i.e. rust is totally prevented.

  • Simultaneously, billions of nuclei are formed on the surface and micro crystals start growing around them. This forms a very tenacious attachment with the sub stratum resulting in a formation of highly complex crystalline structure on the steel surface.

  • During this process, a dense forest of micro crystals is developed on the steel surface which has a great affinity towards cement as well as steel. Finally , the Nanocoat becomes inseparable part of steel and remains unaffected even up to 600 degrees Celsius and stable up to -196 degree Celsius.

  • MCDT (Micro Crystal Development Technology) mentioned here indicates that each crystal nucleus of Steel Guard Nanocoat TM has the power of attracting other cement molecules to it by the virtue of crystal forces and forms a TRAP for all these molecules which do not possess sufficient energy to escape.

  • Chemisorption is another important reaction which is taking place during the reaction where molecules are held on the steel surface by a chemical bond formed between the Nanocoat & steel molecules. The heat of absorption is very high and is difficult to reverse the process i.e. only heating to high temperatures can reverse the chemisorptions.

  • Each crystal of Steel Guard Nanocoat TM is cubic shaped (like crystals of diamond) with a four threefold axes which helps to increase the adherence to steel & concrete simultaneously.

  • Another important reason for the increase in the bonding strength by more than 300% is Nanocoat's physiochemical structure, due to which the active chemical formulation hides the dense forest of micro crystals inside and form a chemical net which attracts minute cement particles. This forms a strong bond between steel & cement.

So, to conclude let’s start a revolution in the steel industry.
