Study of the admixture-cement compatibility for the economic
It has been found that Polycarboxylate Ether (PCE) based superplasticizers show greater compatibility and economical dosage as compared to Sulphonated Napthalene Formaldehyde (SNF) based...
SikaPlast-400 | PCE based Super-plasticizers
Mid-Range Superplasticizing water reducing and retarding concrete admixture. SikaPlast-400 is a polycarboxylate based superplasticizer developed particularly for use in ready mixed concrete to give extended slump retention and high strength development of normal grade concrete mixes. SikaPlast-400 is suitable for use in concrete mixes

- Which superplasticizer is used in setting times of concrete?
- Same performance in setting times of concrete. 4. M40 concrete made with SNF based superplasticizer concrete made with PCE based superplasticizer. This superplasticizer. Same observations are made in concrete. 5. So based on achievement of desired setting times and based superplasticizer. So it is suggested that for the
- Are M40 grade concrete mixes compatible with SNF & PCE based super plasticizers?
- In the present study, compatibility assessment of commercially available cements (OPC and PPC) and SNF & PCE based super plasticizers are made by evaluating the workabilities, setting times and compressive strengths of M40 grade concrete mixes made with two different brands of cement and with two different chemical admixtures.
- Why are superplasticizers used in Indian cementitious mix?
- Superplasticizers are increasingly being used in Indian cementitious mix from the 1980 s onwards as they have proved their credibility in parameters like water and cement reduction apart from workability retention, strength gain, and ease to place and pump.
- Why is superplasticizer incompatibility a problem?
- The cement–admixture (superplasticizer) incompatibility may affect both the fresh state and hardened properties of the cementitious mix - the main ones are rapid loss of workability, excessive quickening/retarding of setting times, low strength gain, excessive air entrainment, and increased risk of shrinkage with moderate cracking.
- Is SNF Based superplasticizer more compatible with M40 grade concrete?
- It was found that M40 concrete made with SNF based superplasticizer has achieved desired compressive strength than the concrete made with PCE based superplasticizer. This shows that SNF based superplasticizer is more compatible for M40 grade concrete than PCE based superplasticizer.
- Does superplasticizer -poly carboxylate ether in cement composites increase strength?
- Our paper reports the addition of high performing superplasticizer -Poly Carboxylate Ether in cement composites as per Indian Standards has resulted in a denser cementitious matrix and higher strength gain at longer terms compared to normal superplasticizers. 1. Introduction
