Setting Time of Concrete
Global lab provide the art of the precise, accurate & reliable testing serviceof Inital & Final setting time for durability Test of Concrete as per IS 8142 : 1976.
FINDING OUT INITIAL AND FINAL SETTING TIME FROM THE GRAPH
From the penetration resistance equal to 3.43 MPa, draw a horizontal line. The point of intersection of this with the smooth curve is read on the x-axis which gives initial setting time.
Similarly a horizontal line is drawn from the penetration resistance of 26.97 MPa and point it cuts the smooth curve is read on the x-axis which gives the final setting time.
Time of setting shall be reported in hours and minutes to the nearest minutes.
