Compatibility of Superplasticizers with Different Cements
The 33 grade ordinary Portland cement has shown retardation with naphthalene-based superplasticizer at the recommended dose (2%) of manufacturer, where as 43 grade OPC has shown retardation with...
Scientists develop alternative cement with low carbon footprint
Summary: Researchers have developed a climate-friendly alternative to conventional cement. Carbon dioxide (CO2) emissions can be reduced during production by up to two thirds when a previously
Studies on green concrete – A review - ScienceDirect
Arun Kumar et al. (2015) examined the strength and durability properties of green concrete by replacing the bottom ash (0, 30, 60, 100%) for river sand. They designed the M50 grade concrete and tested for strength parameters, modulus of elasticity, rapid chloride permeability [12]. Noridah Mohamad et al. (2025) conducted the extensive review on
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
Title: A Review on Plasticizers and Eco-Friendly Bioplasticizers
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887...
- Are M40 grade concrete mixes compatible with SNF & PCE based super plasticizers?
- Abstract. 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 more compatible with brand 2 cement based M40?
- So based on achievement of desired setting times and compressive strengths, it can be concluded that brand 2 cement based M40 concrete (ie, PPC based) is more compatible with SNF based superplasticizer than PCE based superplasticizer. So it is suggested that for the development of PPC based M40 grade concrete SNF superplasticizers can be used.
- How do superplasticizers affect the workability of concrete?
- Superplasticizers directly influence the workability of concrete, and certain factors are considered such as type of admixture, time of addition, addition sequence, mixing time, dosage, w/b ratio, and amount/nature of binder. The dosage between 0.6 to 2% by weight of cement resulted in minimal retardation.
- What is the penetration resistance of concrete mixes with superplasticizer?
- The penetration resistances of concrete mixes with superplasticizer are shown in Tables 3 to 6. M40 concrete made with SNF based superplasticizer has shown better initial and final setting times of concrete than in concrete made with PCE based superplasticizer.
- Is SNF Based superplasticizer better for M40 grade concrete?
- M40 concrete made with SNF based superplasticizer has shown better initial and final setting times of concrete 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.
- What is a superplasticizer in cement mix?
- Superplasticizers (SP) are one of the most important constituents of cement cementitious mix mixes. It makes cementitious mix flowable at a low water-cement ratio without segregation and bleeding as required for high-performance concrete .
