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.
Sika ViscoCrete TS-100 | PCE based Super-plasticizers
Sika ViscoCrete TS-100 is a third generation superplasticizer for high performance concrete. It was particularly formulated for the production of precast tunnel segments, targeting the high demands regarding slump retention, very low water/binder ratios, use of double or triple blend mixes (cement, GGBFS, PFA and/or microsilica) and high degree of compaction.
Plasticizers For Concrete - Principle, Types & Advantages - PRODYOGI
1. Hydrophilic Plasticizers Hydrophilic Plasticizers is characterized by increased wettability, the main function of which is to increase the plastic and flow characteristics of the concrete. 2. Hydrophobizing Plasticizers These type of plasticizer saturates the concrete mixture with a large amount of air.
Super Plasticizers: Classification and Uses | Concrete Technology
Super plasticizers are also used for the production of high strength and high performance 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.
Influence of Fiber Addition on the Properties of High-Performance Concrete
High performance fiber-reinforced concrete (HPFRC) has been frequently investigated in recent years. Plenty of studies have focused on different materials and types of fibers in combination with the concrete matrix. Experimental tests show that fiber dosage improves the energy absorption capacity of concrete and enhances the robustness of concrete elements. Fiber reinforced concrete has also
- 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 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.
- 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.
- 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.
- What are plasticizing cementitious admixtures?
- 3.1. Chemical stability of admixtures in AAC: FTIR analysis Plasticizing cementitious admixtures are designed to improve the properties of Portland cement, which is hydrated with water that has a neutral pH. On the contrary, in AAC, solutions with higher pH are needed to hydrate/activate the cement.
- What is a superplasticizer?
- Superplasticizer is chemical admixtures added to the concrete to improve their flowing ability also known as high range water reducers.
