Cement-superplasticiser compatibility - Issues and challenges
The Compatibility between Super Plasticizer and OPC 53-S cement can be known by conducting three different types of tests. Flow test, Mini Slump test and Penetration tests are conducted and
Compatibility assessment of commercial cements and
used. For these concretes, use of super plasticizers is mandatory to gain workability. At the same time, knowing the compatibility of it with the type of cement used is also essential. The compatible combination of cement and superplatizer results in the optimum dosage of the superplastizer which otherwise lead to use higher dosage and
Selection of Superplasticizers for High-Performance Concrete
The first moment consumption of Superplasticizer molecules after the mixing is qualified as the cement/Superplasticizer compatibility. It is very difficult to make high-performance concrete with a very low water-cement ratio, that it will still have a slump value of 50mm 30 minutes with an initial slump value of 200mm.
SikaPlast-398 SF | Super Plasticizers
SikaPlast-398 SF is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete. SikaPlast-398 SF meets the requirements of ASTM C494 type D & G. SikaPlast-398 SF conforms to type G when used at 0.8 - 1.0% dosage, depending on cement type used. SikaPlast-398 SF combines different modes of
- 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.
- 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
- 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.
- 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.
- 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
- Which chemical admixtures can be used in M40 grade concrete?
- different chemical admixtures. The dosage of SNF and PCE based chemical admixtures to be used in M40 grade concrete is determined using marsh cone test. It was found that M40 concrete made with SNF based superplasticizer. This shows that SNF based superplasticizer is more compatible for M40 grade concrete than PCE based superplasticizer.
