Sika ViscoCrete-5060 | PCE based Super-plasticizers
Sika ViscoCrete-5060 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. Sika ViscoCrete-5060 is suitable for use in concrete mixes incorporating pozzolanic materials such as GGBS, PFA and microsilica. Suitable for use in hot and
studies on compatibility issues of super plasticizers with opc 53-s cement
The dosage of Super Plasticizer (Master Glenium ACE 30) started from 0.2% to 2.2% with respect to cement. Table -5: Flow test results fors CHRYSO Fluid Premia K713 Super Plasticizer with 0.35 and
Sika ViscoCrete-20 HE | PCE based Super-plasticizers
High Range Water Reducer / Superplasticiser. Sika ViscoCrete-20 HE is a liquid admixture for concrete and mortar which is used as high range water reducer or superplasticiser. Sika ViscoCrete-20 HE is designed to work on a combination of electrostatic adsorption and steric repulsion effects allowing solid particles to be effectively
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
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...
- 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?
- 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.
- 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 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 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 .
- 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.
