Top 10 Best Superplasticizer For Concrete – Recommended By
Super plasticizer dosage is 0.5- 1 % by weigh of cementitious material. For 90 lbs(40 kg) (bag of cement) you’ll need approximately0.5(0.20 kg) – 1 lb(0.45 kg) of GlobMarbe super plasticizer. Characteristics / Chemistry Free-flowing, spray dried powder of modified polycarboxylic ether.
Superplasticizer
Superplasticizers ( SPs ), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

- What is the dosage of super plasticizer?
- Super plasticizer dosage is 0.5- 1 % by weigh of cementitious material. For 100 lbs (45.3 kg) (bag of cement) you'll need approximately 1 lb (0.45 kg) of GlobMarbe super plasticizer. We recommend to start with 1% by cement weight, then lower the dosage as needed.
- 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.
- What are the benefits of super plasticizer?
- An increase in paste quality will yield higher compressive and flexural strength, lower permeability, increase resistance to weathering, improve the bond of concrete and reinforcement, reduce the volume change from drying and wetting, and reduce shrinkage cracking tendencies. Super plasticizer dosage is 0.5- 1 % by weigh of cementitious material.
- How much plasticizer do I need for 100 lbs of cement?
- For 100 lbs (45.3 kg) (bag of cement) you'll need approximately 1 lb (0.45 kg) of GlobMarbe super plasticizer. We recommend to start with 1% by cement weight, then lower the dosage as needed. How to mix with Cementitious Material: Mix concrete/cement with plasticizer for a few minutes, then add water (mix at least 3-5 minutes).
- How to mix super plasticizer?
- You can also add Super plasticizer to the water 10-15 minutes prior to casting (until plasticizer dissolves in water), then mix with dry ingredients. Please note: Concrete minimum mixing time is 3 minutes with mechanical drill or 5 minutes with mortar mixer (it takes a few minutes until Super Plasticizer absorbs into the cement and start reaction).
- What is the solvating strength of plasticizer?
- The solvating strength of plasticizer depends on its chemical structure as it relates to its physical properties. Application of Hansen solubility parameters (δ d = dispersion interactive forces, δ p = dipole interactive forces, and δ h = hydrogen bonding forces) is the most successful method of predicting interaction between plasticizers and PVC.
