EPSILONE HW 382 : 3rd generation superplasticizers > Water
New generation polycarboxylate ether superplasticizer "extended slump retention" EPSILONE HW 382 is a highly effective superplasticizer based on modified synthetic carboxylated polymers specifically designed to produce ready mix concrete with low water binder ratio and excellent workability.

For a stated workability, the superplasticizers can effectively scale down the w/c ratio, increases the strength and durability requirements and thereby lower the cement and water content required. Superplasticizers produce high workable mix even at lower w/c ratio without compromising strength. 1.1.2 Cement-Superplasticizer Interaction.

- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- What are polyacrylate ether superplasticizers?
- This work synthesized a series of polyacrylate ether superplasticizers (PAEs) via emulsion polymerization in one-pot. These novel PAEs exhibit superior dispersibility, outstanding fluidity retention, and stronger retardation effect, due to the core–shell nanomicellar configuration.
- What is the difference between a plasticizer and a superplasticizer?
- Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
- What are the different types of superplasticizers?
- According to their dispersing functionality and action mode, one distinguishes two classes of superplasticizers: Steric effects: Polycarboxylates - ether (PCE) synthetic polymers bearing lateral chains (third generation).
- Does a jellyfish-like superplasticizer maintain the fluidity loss of cement?
- Plank et al. reported a new Jellyfish-like superplasticizer, which maintained the fluidity loss of cement past only at 8.5% after mixing 6 h . Liu group synthesized novel star-shaped polycarboxylate superplasticizers, exhibiting superior fluidity retention than the comb-type ones .
- Which superplasticizer is best for cementitious mix?
- The superplasticizers with a high-order configuration including star, branched, clawed or corosslinked shape, have exhibited superior fluidity retention effect in cementitious mixes, but are often prepared with tedious routes.
