  • 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.
  • Does self-compacting geopolymer concrete improve compressive strength?
  • Although the addition of slag on GPC improves compressive strength even at ambient temperature but reduces workability. To resolve these problems, self-compacting geopolymer concrete (SCGC) was introduced in 2011, which can be settled by its weight without the need to use any type of compaction technique .
  • Does superplasticizer affect workability and properties of self-compacting concrete (SCC)?
  • This research examined the effect of superplasticizer on workability and properties of self-compacting concrete (SCC). Three types of superplasticizers Conplast SP 561, Conplast SP 430 and Conplast SP 264 at different percentages (0, 10, 20 and 30%) with the same water cement ratio of 0.3, with M30 grade of concrete.
  • What is the optimum superplasticizer dosage for geopolymer concrete?
  • Superplasticizer dosage of 6% is taken as the optimum because no significant contribution of SP dosage of 7%. As the concentration of NaOH solution increased from 8M to 12M, the compressive strength of geopolymer concrete was increased. But the strength decreased when the concentration increased from 12M to 14M.
  • What is super plasticizer (Sika Visco Crete 3430)?
  • Super plasticizer (Sika Visco Crete-3430) was used to increase the workability to the extent required for self compactability of Geopolymer Concrete. The utilization of Viscosity Modifying Admixture (VMA) gives more possibilities of controlling segregation (stability) and homogeneity of the mix .
  • What is self-compacting concrete?
  • ... Self-compacting concrete (SCC) is a type of concrete that is compacted due to its own weight, having limited coarse and fine aggregate (Su et al. 2001;Okamura and Ouchi 2003; Olowofoyeku et al. 2019).
