Cracks in the concrete Part 3 Different types of cracks

Different types of cracks1 - cracks active (continuously expanding)A - vertical cracks.B - oblique cracks.An increase in torque.Increase in shear.2 - static cracks.A - vertical or oblique temporary increase in businessB - a separate incisions extended the full length of the structural member of shrinkage is governed by the movement or temperature controlled movementC - when you change to your sector of the local concentration of stressesD - cracking when you change the origin in the form of lack of connections in control (breaks down or stretching)E - cracking moments in a separate area to be moments where a few bars in the area stopped working the beginning of the crackAnd - surface cracks static address weak - loss of surface water - strong winds during the casting.3 - scattering and the fragmentation of concrete strains over-pressure or chemical attack4 - swelling and enlargement of gravel in the concrete interaction of alkali5 - change the color of concrete, chemical attack, the growth of algae, steel rebar.6 - the erosion of concrete abrasion or friction of concrete, chemical attack, and concrete with high permeability.7 - occurrence of stress and submission to the iron overload8 - Iron Inqsaf anatomical occurrence of brittle fracture or stress fatigue of the arrival of Iron9 - plus an elision of the member movements of structural foundations, overloading, wrong to put rebar.10 - steel rebar permeability of concrete cover, connect the stray electric current.
