Polycarboxylate Superplasticizers - Concrete Construction
Polycarboxylate Superplasticizers. Some 20 years ago, a new type of superplasticizer based on polycarboxylate polymers (PCE) was commercially introduced to the North American concrete construction industry. Just as the application of naphthalene-based admixtures starting in the 1970s enabled significant improvements in the numerous engineering
Superplasticizer I Concrete admixtures I Super plasticizer
Superplasticizer is especially optimized for plastification and water reduction of cementitious construction materials. Superplasticizer provides an excellent development of early strength. Fields of application are : Self-levelling underlayments (SLU) Feather-edge products Non-shrink grouts Cementitious floor screeds

- What is a superplasticizer admixture?
- Superplasticizers are water-reducing admixtures used in concrete production to reduce the need for more than 30% of water. They operate at a certain percentage level. One of their main purposes is to prevent concrete from setting too quickly.
- What is a superplasticizer?
- Er. Kaushal Kishore , Superplasticizers belongs to a class of water reducer chemically different from the normal water reducers and capable of reducing water content by about 30%.
- How many GM of super plasticizer per kg?
- Super plasticizer conforming to IS:9103-1999. With the given requirements and materials, the manufacturer of Normal Super plasticizer recommends dosages of 20 gm per kg of OPC, which will reduce 28% of water without loss of workability. For fly ash included cement dosages will be required to be adjusted by experience/ trials.
- How much OPC should a normal super plasticizer be used for?
- With the given requirements and materials, the manufacturer of Normal Super plasticizer recommends dosages of 20 gm per kg of OPC, which will reduce 28% of water without loss of workability. For fly ash included cement dosages will be required to be adjusted by experience/ trials. 1.
- Do superplasticizers reduce water in concrete mixes?
- The benefits obtained by Superplasticizers in the reduction of water in the concrete mixes are best illustrated by the following examples. With PPC (Flyash based) conforming to IS:1489-part-I-1991. 7 days strength 38.5 N/mm 2.
- What are the different types of superplasticizers?
- The Superplasticizers are broadly classified into four groups: sulfonated melamine formaldehyde condensate (SMF), sulphonated naphthalene formaldehyde condensate (SNF), modified lignosulphonate (MLS) and others including sulphonic acid ester, polyacrylates, polystryrene sulphonates, etc.
