Du Pump Concrete Admixtures

American Concrete Institute

Concrete admixtures have various functions and they are as follows: (a) To increase the rate of strength development at early ages – calcium chloride is the most widely used accelerator, (b) To retard the initial setting time while pumping concrete over a long distance, (c To increase the workability without changing the water content

CONCRETE 101

cement and aggregates (without admixtures), the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good average slump for pumping. Above average slump - due to the addition of water – considerably reduces the strength, durability, and permeability of concrete and can cause segregation.
