One of the basic attributes of any concrete is its workability or consistence , that is, how easy it is to push one way, pull the other, and float to a smooth level surface. workability is largely determined by how fluid the concrete is. this is referred to as slump.
Required slump = 50-75 mm. so modifications and changes are needed in trial mix 1 to get the desired workability. concrete trial mix 2: to increase the workability of concrete mix from 25 mm to 50-75 mm an increase in water content by +3% is to be made. the corrected water content for mix =.
