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
Delay Set Superplasticizer | Fritz-Pak | Concrete Admixtures
The delay set feature of the products helps keep the first layer of concrete plastic as you work your way around the forms. As a premium superplasticizer, this admixture offers up to 40% water reduction and a Supercizer 7 does not contain hazardous materials and comes packaged in our signature water-soluble bags.
Study of the admixture-cement compatibility for the
It has been found that Polycarboxylate Ether (PCE) based superplasticizers show greater compatibility and economical dosage as compared to Sulphonated Napthalene Formaldehyde (SNF) based...
Self-Compacting Concrete using Superplasticizers A Review
different super-plasticizers for SCC using marsh cone. For this study, three different brands of PCE based superplasticizers were used. The paper concludes that all the three superplasticizers are compatible with cement but their optimum dosage differs. S M Maheshwarappa[12] et.al (2014) studied the effect of

- 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
- 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.
- 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.
- Does superplasticizer increase setting times of concrete?
- The addition of superplasticizer to the concrete increases the setting times of the concrete. Table 2. Four M40 grade concrete samples were prepared with 2 brands of cement and 2 types of admixtures and tested for setting times of concrete. The setting time of concrete are determined as per IS: 8142(1976) using penetration resistance apparatus.
- 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.
- 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
