Admixtures | Super Plasticizers - RussTech
RussTech carries a full line of super plasticizing concrete admixtures including ones that contain the new polycarboxylate technology. These high range water reducers have been specifically designed to increase strength while maintaining extended flowability at lower water to cementitious ratios in the concrete mix. SuperFlo 443. SuperFlo 2000RM.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers are mainly used in pumping concrete, casting heavily reinforced members and precast elements of concrete. Advantages of Superplasticizer: 1. Superplasticizers reduces the water content. 2. It reduces the cement content. 3. Also, increases the workability of concrete. 4. It reduces the permeability of concrete. 5.
15 Types of Admixtures Used in Concrete - The Constructor
Some of the new generation super plasticizers are acrylic polymer based, poly carboxylate, multicarbovylatethers etc. Fig 1: Water Reducing Admixture 2. Retarding Admixtures Retarding admixtures slow down the rate of hydration of cement in its initial stage and increase the initial setting time of concrete.
Experimental Investigation on PCE and SNF Type Admixture on
Optimum dosage of super plasticizer improves the workability of concrete without adding excess water. At a dosage of 0.5% of SNF super plasticizer (Sikament 2002 NS) and 25% water reduction, maximum strength achieved. At 0.6% of PCE super plasticizer (C Flow 175 M) and 25% water reduction all the strength parameters reached peak value.
- What is a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes. They achieve a reduction in water content without loss of workability.
- What is a superplasticizer?
- Superplasticizer is chemical admixtures added to the concrete to improve their flowing ability also known as high range water reducers.
- Can super plasticizers reduce water content in concrete mix?
- The use of super plasticizers can permit the reduction of water in the concrete mix upto 30% without producing any ill effect on the workability of the concrete i.e. without reduction in the workability of concrete, where as normal plasticizers with doses upto 0.1 to 0.4% by weight of cement can reduce water content from 5 to 15%.
- 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 is globmarble super plasticizer?
- GlobMarble super plasticizer is especially optimized for plastification and water reduction of cementitious construction materials. Super plasticizer provides an excellent development of early strength. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture.
- What is a high-performance superplasticizer?
- A high-performance superplasticizer can be prepared by using bio-polymer chitosan as a raw material by chemical performance. This greatly improves the strength of high strength concrete with the presence of silica fume. Hello, I'm Rahul Patil founder of Constructionor.com, I had studied B.E. Civil.
