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 â€¦...
is an agent. which may be added to mortar or concrete to improve its workability by increasing air entrainment.
'A compound added to a polymer to make it softer and more flexible. These are usually small molecules with dangling bits that can disrupt the packing of polymer chains. A common plasticiser used to soften PVC is dioctyl phthalate:

A plasticiser is a substance which when added to a material, usually a plastic but also a paint or an adhesive, makes it flexible, resilient and easier to handle. Modern plasticisers are manmade organic chemicals; the majority of which are esters, such as adipates and phthalates. They are major components that determine the physical properties of p...Found on http://www.eurochlor.org/mainglossary
