Emerging Technology : Self Healing Concrete

In the construction sector some new invention occur such as Self Healing Concrete. Some critical problems are occur in the concrete which is occur due to variation of temperature,mixing, curing is not done properly, etc. Solution for that problem is coming called as Self Healing Concrete. 

Why need ?

• For avoiding the cracks which are developed in concrete.
• To avoiding water seeps through concrete pores
• Concrete is well stand with compressive strength but not  enough stands with tensile strength.
• Structure built in underground for marine then there is salt present in water & that salt penetrates into concrete result in corrosion of reinforcement in concrete.
• For removing bacteria like rust, salt, etc which are present in concrete.

Ingridients:

• Concrete : 1) Cement 2) Sand 3) Aggregate 4) Water
• Bacillus
• Calcium Lactate 
• Nitrogen
• Phosphate
  
  
  
  

Advantages:

• Increase strength of concrete
• Cracks can be reduced
• Corrosion of reinforcement are reduced like negligible
• It reduce the permeability
• Maintenance cost is lower
• It has lower water absorption
• It provide the better resistance against snow attack & frezing

Disadvantages:

• The uses of self healing concrete is limited to structure because it contain bacteria & it is not good for human health
