Abstract :
Concrete is a fundamental construction material
which is one of the main reasons for an structure to survive
for a long duration of time. The binding ability , its high
compressibility and strength retaining capability makes it
more durable. But, there are some factors which can
harness the durability of the concrete with respect to time
and can reduce the longevity or the age of the structure such
as chloride attack, sulphate attack, freezing, thawing etc.
This result in degradation of structure and formation of
cracks. These cracks plays a vital role in tempering the
durability of structure providing a clean passage to water
to seep in deep to the reinforcement and here the problems
arises. So, some bacteria which can react with water and
can form precipitates in powdered form are injected during
the baching process.This process is termed as Self healing
of concrete. These bacteria can also play a pivotal role in
altering the concrete properties. So in this review we are
going to study the effect of these bacteria on concrete
properties in positive way possible
