Definition:
-
Separating the components of a heterogeneous mixture
so that their distribution is not uniform.
Reason:
-
Segregation is caused by following five reasons:-
Big difference in the size of the aggregates.
Big difference in specific gravity of aggregates.
Improper handling of concrete.
Vibration of concrete.
Improper grading of aggregates.
Harmful
effects due to the segregation of concrete: -
Honey comb of concrete.
High permeability of concrete.
Low compressive strength.
Poor finishing of surfaces.
Control
of Segregation: -
We can control the segregation of concrete in the
following ways:
By properly selecting the set.
By proper handling of concrete.
Applying controlled vibration.
Adopting leak proof form work.
Differences between:
Whole Circle Bearing vs Quadrantal Bearing
Lintel level vs Sill level vs Plinth level
Construction Joint vsExpansion Joint
Site Engineer vs SiteSupervisor
