Role of Superplasticizer on GGBS based Geopolymer Concrete under
The GGBS based geopolymer concrete had been examined with varying superplasticizer doages as shown in Fig.3. Mix M1 with 3% of superplasticizer was achieved 140 mm slump. Mix M2 with 4% of superplasticizer was achieved 155 mm slump. Mix M3 with 5% was achieved 175 mm and Mix M4 with 6% was achieved 190 mm.
Addition of superplasticizer on geopolymer concrete - ResearchGate
The superplasticizer (Conplast SP-430) was added by 1.5% of the cementitious materials by mass. This was in accordance with the findings that 1.5% of the naphthalene-based superplasticizer by...
ADDITION OF SUPERPLASTICIZER ON GEOPOLYMER CONCRETE - ARPN Journals
alkali activator in fly-ash would make geopolymer concrete. The addition of high-range water-reducing admixture up to approximately 2% of fly-ash mass have improved the workability of fresh geopolymer concrete.In this study the mixtures of geopolymer binder were made with the ratio of fly-ash and alkali activator were 74%: 26%, molarity of sodium
Influence of Superplasticizer on Workability and Early
Generally, superplasticizer used in OPC concrete aims at high workability without excessive addition of water, and thus appropriate compressive strength can be obtained. Polycarboxylate based superplasticizer was found to retard the setting time of Ca(OH) 2 /Na 2 SO 4 activated geopolymer paste [ 1 ].

- Does superplasticizer doage affect workability and strength of geopolymer concrete?
- Increase in the dosage of superplasticizer can have a significant effect on workability and strength properties of Geopolymer concrete in ambient curing. This paper evaluates the influence of different superplasticizer doage on workability and strength properties of GGBS based Geopolymer concrete.
- What is self-compacting geopolymer concrete (SCGC)?
- Self-compacting geopolymer concrete (SCGC) is produced from waste materials that act as binders or precursors promoting sustainable concrete. Among all components of the SCGC mix, the superplasticizer dosage primarily controls the workability of concrete along with mechanical strength.
- How to make geopolymer concrete based on fly ash?
- Today one of the alternative solution is geopolymer concrete, it is based on fly-ash or other material pozzolanic. Byadding some alkali activator in fly-ash would make geopolymer concrete. The addition of high-range water-reducing admixture up to approximately 2% of fly-ash mass have improved the workability of fresh geopolymer concrete.
- What are the different types of superplasticizers?
- superplasticizers considered are PCE-based, NA-based, LS-based, and ML-type. Fresh property study: filling ability; passing ability, and resistance to segregation test. Self-compacting geopolymer concrete (SCGC) is produced from waste materials that act as binders or precursors promoting sustainable concrete.
- Does commercial superplasticizer affect concrete workability?
- Commercial superplasticizer (SP) of several verities is available and change in a very less percentage (even 1%) of SP affects concrete workability significantly which can’t be noticed in the case of extra water (EW).
- Does superplasticizer increase workability under ambient curing?
- Significant increase in workability and slight decrease in strength was observed with increase in superplasticizer under ambient curing. The combination of 6% superplasticizer and 12M NaOH concentration of GGBS based Geopolymer concrete was advisable for precast construction under ambient curing.
