The equivalent superplasticizer to the one used in the video is WR310. I generally prefer working with a liquid superplasticizer such as WR420. 5. Segregation “Sometimes a good concrete mix can segregate when too much superplasticizer is used.” Ideally, all ingredients in your mix are evenly distributed.
Accelerating admixtures are used to reduce the initial setting time of concrete. They speed up the process of initial stage of hardening of concrete hence they are also called as accelerators. These accelerators also improves the strength of concrete in it early stage by increasing the rate of hydration.
Also useful to make high early strength concrete for long over hauls & suspended slup retention, Superplasticizer Admixture is perfectly appropriate for concrete made with broken sand and commercialized RMC plants.

Fritz-Pak's Super Slump Buster is an easy to use, powdered viscosity modifying admixture (VMA). It is used to reduce the slump of concrete, essentially performing the opposite of a high range water reducer (superplasticizer). It also helps prevent segregation in aggregate-based mixes. Please see the product page for detailed information about dosing and mixing procedure.
commonly used in oil well cementing. This blender was chosen because its shear force best simulates the mixing conditions and friction forces occuring when concrete is prepared in a compulsory mixer (Farrington 2007). Ce-ment and silica fume were preblended in dry form while the superplasticizer was dissolved in the mixing water.

useful and important properties. Master glenium superplasticizer is used as super plasticizer in this research. High strength concrete can be made by using low water to cement ratio but water to binder ratio will give more strength . KEYWORDS-silica fume, super plasticizer, compressive strength. I. INTRODUCTION
WATER REDUCERS are used for two different purposes: (1) to lower the water content in plastic concrete and increase its strength, and (2) to obtain higher slump without adding water. Water-reducers will generally reduce the required water content of a concrete mixture for a given slump.
Superplasticizer has a strong dispersing effect on the cement, which can greatly improve the fluidity and slump of the concrete, reduce the water consumption, and significantly improve the workability of the concrete. Adding superplasticizer can improve the strength of concrete at different ages and save cement.
1 The dosage of this polycarboxylate superplasticizer for normal strength and high strength concrete is. typically 0.6%~1.2% and 1.2%~1.8% respectively, the recommended dosage for GB8076 standard test is 1.0%. 2 The amount used in concrete will be slightly adjusted depending upon job requirements,

It can be widely used in premix of common concrete, gushing concrete, super fluid state of self-compacting concrete and concrete of high strength and durability. It is more useful in high-strength and high performance concrete, precast concrete and concrete of super-fluid state to avoid self-leveled vibrating. Specifications
RE: Slump test after adding Super P? cvg (Civil/Environmental) 17 Mar 09 14:10 in over 23 years of experience, I have never seen slump, air or temperature measured before adding an admixture at the site - measurements have always been taken right before the concrete is placed in the forms.
Superplasticizer is a chemical admixture used where well-dispersed particle suspension is required. These polymers are used as a type of dispersants to improve the flow characteristics of suspensions and avoid particle segregation in concrete applications.
The superplasticizer is very useful to reduce mixing water in fresh concrete, which results in the enhancement of watertightness and strength of hardened concrete. But it has a limit of not preventing steel bar embedded in concrete ...

Superplasticizer is a type of water reducers; however, the difference between superplasticizer and water reducer is that superplasticizer will significantly reduce the water required for concrete mixing 2 . Generally, there are four main categories of superplasticizer: sulfonated melamine- formaldehyde
Superplasticizer is useful for getting concrete into tight areas such as corners and turns without using excessive water. Fibermesh: A polypropylene fiber mesh product added at the concrete plant that eliminates the use of wire mesh.

CBD-203. Superplasticizers in Concrete. Originally published February 1979. V.S. Ramachandran. A superplasticizer is one of a class of admixtures called water-reducers that are used to lower the mix water requirement of concrete.
General speaking, Ducon concrete plasticizers for sale can be used in concrete and construction industry. Our plasticizer concrete admixture can reduce the water content without affecting the workability of concrete, and also increase the strength of the concrete.
it is used as a highly effective water-reducing agent and superplasticizer for the production of high quality, free flowing concrete in hot climate. Use Its used wherever high quality concrete is demanded under difficult placing and climatic conditions.
