A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong. Types of Plasticizers in ...
