Detailed Solution
Download Solution PDFExplanation:
Water-reducing admixtures, often based on plasticizers or superplasticizers, are chemical agents added to concrete to:
-
Enhance workability (ease of placing and compaction)
-
Maintain or increase strength without increasing water-cement ratio
-
Reduce water demand for a given slump
They function by dispersing cement particles more efficiently and reducing water film thickness without reducing flowability.
Additional Information
-
When water content is reduced without sacrificing workability, the water-cement ratio decreases.
-
A lower water-cement ratio leads to:
-
Higher compressive strength
-
Lower permeability
-
Improved durability
