Superplasticizer for High Strength Concrete - ResearchGate
The general trend seen in both the viscosity measurements and spread test is that the high composition superplasticizer produced the lower viscosity and highest spread, followed by the medium...
Superplasticizers for High Performance Concrete - Rice Husk Ash
The use of HPC would lead to an increase in the usage of Microsilica and Super Plasticizers. A new generation Super Plasticizer would be necessitated considering the stringent requirement of high workability, self-compactions and long hauling times and Super Platicizers will have to cater to these new conditions.
- Which superplasticizer admixture is better?
- Based on the findings, out of three superplasticizers, PC—based admixture showed a better improvement in strength aspects compared to other mix. Compressive strength of UHPC (a) SNF admixture (b) SMF admixture (c) PC admixture
- What is the most effective superplasticizer?
- Among the most effective superplasticizers are comb- type copolymers which consist of an anionic backbone and uncharged side chains (Sakai et al. 2003; Plank 2004). Recently, ultra-high strength concretes possessing very low w/c ratios (< 0.25) and a high content of fines were developed.
- Are polycarboxylate superplasticizers effective in ultra-high strength concrete?
- Effectiveness of Polycarboxylate Superplasticizers in Ultra-High Strength Concrete: The Importance of PCE Compatibility with Silica Fume Methacrylate ester as well as allylether based polycarboxylates (PCEs) were synthesized to plasticize pastes of cement and silica fume having a water/cement ratio of 0.22.
- What is the maximum tensile strength of a superplasticizer?
- The maximum split tensile strength at 28 days of testing for all cases was found to be 29.09 MPa—SNF based, 30.72 MPa—SMF based, and 31.23 MPa—PC-based admixture, respectively, at 1.5% of dosage (Fig. 6). Therefore, the effect of superplasticizers mainly influences the workability of concrete rather mechanical properties.
- What is polycarboxylate superplasticizer (PCE)?
- As one important auxiliary, superplasticizers have attracted lots of attention in the concrete and building materials field. Specially, polycarboxylate superplasticizer (PCE) has been widely applied due to its relatively low doping amount, high water reducing rate and environmental friendliness property.
- 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.
