INTRODUCTION
Cracks result in building when applied
forces are greater than those which the
building or its part can withstand.
LOOPHOLES OF CRACKS
CAUSES OF CRACKS
Non Structural cracks
Moisture changes
Thermal movement
Elastic deformation
Chemical reaction
Foundation movement and settlement of soil
Vegetation
Structural cracks
due to incorrect design
faulty construction
Overloading
Moisture Changes
Building
materials
expand
on
absorbing moisture and shrink on
drying. These are generally reversible.
Shrinkage in concrete or mortar
depends on a number of factors
Cement concrete
Water Content
Aggregates
Curing
Excessive fines
