Superplasticizer: Types, Advantages & Disadvantages
网页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.
Superplasticizer - an overview | ScienceDirect Topics
网页Superplasticizer is a common additive for grouting materials, and its main function is to provide enough fluidity [16,21,53,58,63]. Precisely speaking, it is the superplasticizer adsorption that plays a key role in influencing the flowability of grouts.
