Influence of superplasticizer on the properties of geopolymer
The influence of different alkali and alkaline earth cations (Na +, K +, Ca 2+, and Mg 2+), and of solution pH, on surface interactions of metakaolin particles with a sodium naphthalene sulfonate formaldehyde polymer (SNSFP) (a commercial superplasticizer for concretes) was investigated in aqueous systems relevant to alkali-activated and blended Portland cements.

Investigation on Concrete Properties for Nano Silica Concrete
- Polycarboxylates super plasticizers (PSP) is the most effective of all the chemicals. These can cause a reduction in water content of as much as 40%. Thus, they are highly preferred to make high and ultra high strength concrete, where the w/c may be as low as 0.20.
- What is polycarboxylate superplasticizer (PC-P)?
- Polycarboxylate Superplasticizer (PC-P) is free-flowing and spray dried powder, affords excellent control over initial and final setting times. PC-P is a free flowing and spray dried powder of new generation polycarboxylate based polymer used as a superplasticizer for cement-based materials.
- How to mix polycarboxylate superplasticizer?
- Polycarboxylate Superplasticizer must preferably be added in the mixing water and in case of ready-mix concrete where the product can be added on fresh concrete and in a mixing truck, it is necessary to mix at a high speed for about 6 – 8 minutes. Setting Time Deff.
- Is PC-P a naphthalene or melamine based superplasticizer?
- PC-P is also a superplasticizer for high performance concrete, high strength concrete, high volume fly ash/slag concrete, and grouting/self-leveling screed/mortar. It complies with ASTM C 494, Type-F specifications. Comparing to naphthalene and melamine-based superplasticizers, PC-P has superior characteristics of:
- How much PC-P should a concrete mix have?
- Setting Time Deff. The recommended dosage of PC-P for various applications is 0.02 to 0.3% of cementitious binder. Polycarboxylate Superplasticizer affords excellent control over initial and final setting times. Setting times of concrete mixes are related to cement type, mix design and ambient temperature.
