Superplasticizer: Types, Advantages Disadvantages

Superplasticizer is also known as high range water reducers, it produces extreme workability flowing concrete. It has the efficiency of dispersing fine-grained particles like cement, fly ash, ground granulated blast furnace slag, and silica. They increase slump for ease of placement, creates the denser and more durable concrete.
