ion through a crack depends on:
1. Construction of a building
2. Degree of exposure
3. Capillarity of fine cracks
4. Wind driven rain penetration through wide cracks
CAUSES OF CRACKS
 Structural cracks
 Due to incorrect design
 Faulty construction
 Overloading
 Non Structural cracks
 Moisture changes
 Thermal movement
 Elastic deformation
 Chemical reaction
 Foundation movement
 Settlement of soil
 Vegetation
CHANGE IN MOISTURE
Most building materials expend when they absorb moisture from atmosphere and shrink when they a..................[:=> Show Contents <=:]

here the depth of repair is less than 1-1/2 inches and the exposure conditions are such that relatively constant temperatures can be expected
Epoxy mortars have thermal coefficients of expansion that may be significantly different from conventional concrete
epoxy injection equipment
difference in potential can result in the formation of a galvanic corrosion cell with accelerated corrosion at the repair perimeters
The epoxy bond coat and epoxy mortar create zones of electrical potential that are different from the electrical potential in the surrounding concrete
Polymer Concrete

dation Movement and Settlement of Soil
Shear cracks occur in buildings when there is large differential settlement of foundation due to any of following causes.
• Unequal bearing pressure under different parts of the structure
• Bearing pressure being in excess of safe bearing strength of the soil
• Low factor of safety in the design of foundations
• Local variation in the nature of supporting soil
Buildings on expansion clays are extremely crack prone. The soil movement in such clay is more appreciable upto a depth of 1.5 to 2M and this cause swelling and shrinkage and r..................[:=> Show Contents <=:]
