  • What is a super plasticizer?
  • Classification of Super Plasticizers 3. Uses. Super plasticizers are also called high range water reducers. They are of recent origin and relatively are more effective type water reducing admixtures. They were developed in Japan and Germany during 1960 and 1970 respectively. Chemically they are different from normal plasticizers.
  • Which super plasticizer is best for high performance concrete?
  • Multicarboxylatether: For the production of high performance concrete new generation super plasticizer named multicarboxylatether (MCE) is found more effective. The properties of these super plasticizers are found as follows: 1. The water reduction is found high. 2. At low water/cement ratio their flow ability is found excellent.
  • How a super plasticizer can be used to make 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.
  • What is the difference between shaliplast PCE 200 & PCE 300?
  • ShaliPlast PCE® 200 is a third generation Poly-Carboxylated Ether based super-plasticizer for lower and medium grade concrete and mortar. High Performance Poly-Carboxylated Ether Based Superplasticiser ShaliPlast® PCE 300 is a third generation Poly-Carboxylated Ether based super-plasticizer for concrete and mortar.
  • Why do super plasticizers increase compressive strength?
  • Thus it can be said that the increase in compressive strength is due to the ability of CAE to reduce more water content for the same workability. The effect of super plasticizers is shown with different water/cement ratio on 1 to 3 days strength in Fig. 6.25.
  • Do super plasticizers entrain air in concrete?
  • As super plasticizers do not reduce the surface tension of water to a great extent, they have not found to entrain significant amount of air in concrete.
