Plasticiser

An agent added to fresh concrete that reduces the amount of water needed but gives an equivalent workability, or slump. Reducing the water content also reduces the need for costly cement powder; therefore strength is maintained at a lower cost. Increasing the amount of plasticiser will result in a delaying setting time (retardation), giving increas …...
