Finishing Poured Concrete Surfaces
2
Finishing Concrete A. Consolidating concrete in order to give the uniform plastic mass desired. Tools used in consolidating concrete. $ Straight edge $ Tampers $ Roller screeds $ Jitterbugs $ Vibrator
3
Finishing Concrete B. Striking-off
A leveling operation that takes the humps and valleys out of the surface of the concrete and gives it a true even surface.
4
Finishing Concrete C. Floating
$ It helps depress the coarser aggregate and brings mortar to the surface. $ Tools used for floating concrete. - Darby - Bull float - Wood float
5
Finishing Concrete D. Types of finishes $ Broom finish
- Used for feeding floors, ramps for livestock, driveways and walkways. - The rough texture can be made with a stiff floor broom pulled, crossways to the direction of travel. The degree of coarseness can be determined by the types of broom and the amount of pressure applied to it. $ Belt finish - Used on driveways, pavements, and livestock ramps. - Six inch wide strips of burlap, canvas, or rubber belt can be moved back and forth just after the wood float process is finished.
