IMPACTS OF USE OF SUPER-PLASTICIZER ON PROPERTIES OF CONCRETE
Three types of indigenous super plasticizers were taken from the different supply sources. The various super-plasticizers used for this study are CMC- Super Plast, sikament-600 and CICO-Super Plast. The concentration / dosage level of super-plasticizers are considered to be ranging from 0.5%, 1.0%, 1.5% and 2.0% and
Sibur Plans Plasticizer Plant in Perm, Russia | CHEManager
The Perm subsidiary of Russian gas and petrochemicals giant Sibur and the Perm territorial government have signed an eight-year special investment contract to set up a plant producing the plasticizer dioctyl terephthalate (DOTP). A special investment contract is a new non-financial instrument, designed to promote and support the creation of new
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content.
- 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 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 is a superplasticizer admixture?
- Superplasticizers belong to a class of water reducers chemically different from the normal water reducers and capable of reducing water contents by about 30%. The admixtures belonging to this class are variously known as superplasticizers,” “superfluidizers,” “superfluidifiers,” “super water reducers,” or “high range water reducers.”
- When were superplasticizers used?
- In North America they were used from 1974.1’1 The advantages derived by the use of superplasticizers include pro-duction of concrete having high workability for easy placement, and pro- duction of high strength concrete with normal workability but with a lower water content.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance superplasticizer, follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- What are the advantages and disadvantages of superplasticizers?
- The advantages of superplasticizers include: (1) production of concrete having high workability for easy placement, and (2) production of high strength concrete with normal workability but with a lower water content.
