Super Plasticizers: Classification and Uses Concrete ...

With the use of super plasticizers, flowing concrete could be produced with the water/cement ratio as low as 0.25 or even less. The strength of such concrete was found 120 MPa (1200 kg/cm 2) or more. The use of super plasticizers also made it possible to use the fly ash, slag and silica fume to produce high quality concrete. Classification of Super Plasticizers: Following polymers are commonly ...

Effect of Super plasticizer for Improvement of Concrete ...

Keywords: Concrete, Super Plasticizer, Compressive strength. I. INTRODUCTION Concrete is a composite material in which a binding material mixed in water on solidification binds the inert particles of well graded fine and coarse aggregates. Cement and lime are generally used as binding materials, whereas sand cinder is used as fine aggregates and crushed stones, gravel, broken bricks, clinkers ...

Superplasticizers in Concrete - Building Research

Plasticizers indirectly add strength to hardened concrete by enhancing workability of a concrete mix during its mixing and placing thereby allowing reduction in water-cement (W/C) ratio. Reduction in water cement ratio increases the strength of concrete. Also, reduction in cement content for a given strength thereby decreasing in heat of hydration and cost saving is also possible by the use of ...

Use of Water Reducers, Retarders, and Superplasticizer

Figure 3 Relation between Flow Table and Water Content of Concrete with and without Plasticizers (Neville, 1995). Another benefit of superplasticizers is concrete early strength enhancement (50 to 75%). The initial setting time may be accelerated up to an hour earlier or retarded to be an hour later according to its chemical reaction. Retardation is sometimes associated with range of cement ...

What is the role of water cement ratio in concrete technology?

16/05/2020  If you want to make concrete with lesser W/C ratio then plasticizer (Water Reducer)or super plasticizer (High Range Water Reducer) are used help to decerese the W/C ratio. This admixture are used in Self compacting concrete. What happen if we increase the ratio: The test are conducted on concrete and see that If we increase the w/c ratio of the concrete the then strength is decreasing.
