In case of lean concrete the preciseness of cement minimum that is cement is very low below m10 great concrete is known lean concrete. this type of concrete is generally use for filing rough casting e.t.c|
In IS:456-2000 the workability of concrete is given in mm
(slump)in cl.7.1. In IS:10262-1982, cl.3.3.4 & table-6 says
+/- 3 percent adjustment is required in the quantity of
water (calculated as per table-4 or 5), for each increase
or decrease in the value of compacting factor (i.e.
workability of concrete) by 0.1.
How it is possible to calculate the exact quantity of water
required for a particular grade of concrete?
What is the relation between Slump & Compacting factor of
