Self-Healing Concrete (Bio Concrete)
Executive Summary
This report has been focused on the concept of bio
concrete in construction industry. The use of bio
concrete has been helping in enhancing the strength and
durability of concrete used in the construction industry.
This concrete has been helping in self-healing property

by the use of bacteria in concrete. This report discusses
about advantages and disadvantages of bio concrete in
construction industry. The current application of bio
concrete in the construction industry has been
discussed. There have been a proper comparison of bio
concrete with traditional concrete have done.

Introduction
Concrete has been the most important building
material for construction industry. Concrete is made up
of water, coarse, fine and cement. Cement has been the
most essential part of concrete material. It helps in
binding aggregates and fill voids between coarse and
fine particles. However, concrete have high tendency to
bear cracks in the infrastructure. Small cracks on
surface of concrete makes all structure look vulnerable
as water seeps to degrading the concrete and corrode
the steel reinforcement and decreasing the life span
(Khaliq and Ehsan 2016). However, when it is subjected
for creating tension, it starts to crack more. Therefore,
this have been a big issue with the concrete used in the
construction industry. Various structures are made in
water or nearby water sources. For example, Motorway
bridges have been vulnerable as salts have been used for
de-ice roads penetrating into the cracks and accelerate
the corrosion of steel reinforcement. In various cases of
civil engineering, corrosion have been the main issue for
engineers to maintain properly. Repairs can be done
properly however, it is a time consuming process. In
several cases, it become difficult to reach to critical
points for repairing cracks. Along with this, concrete
suffers from relatively low tensile strength and ductility.
Therefore, to reduce this issue in construction
industry, Bio Concrete is used in the construction
industry. This report deals with various aspects of bio
concrete and how it works as self-healing concrete.
