1.3.3.2 Water reducing

• Also known as plasticizer

• Is a surface active agent to support the cement

distribute efficiently in the water.

• Adding this material in concrete mix would increase

the workability of mix

• Require less water to make a concrete equal slump or

increase a slump of concrete at the same water

content

• As a result the followings can be achieved:

– Higher workability with strength unchanged

– Higher strength with workability unchanged

– Less cement for same strength and workability
