People also ask
What is the compressive strength of geopolymer concrete?
Geopolymer concretes compressive strength only achieves around 50-60% of the planned. geopolymer concrete by 7 days old achieved 67 MPa after curing for 24 hours at 600C.
Why is geopolymer concrete not used?
There are a number of challenges to the more widespread use of geopolymer concrete in projects: No international standard for either manufacture or design • Cost disadvantages due to lack of economies of scale • Availability from suppliers • Lack of older geopolymer structures locally to confirm long-term durability.
What are the problems with geopolymer concrete?
Geopolymer binders cured at room temperature exhibited significantly higher shrinkage than Portland cement does, while thermal cured products are very volumetrically stable. Moreover, alkali-aggregate reaction can happen when alkali-reactive aggregates are used with geopolymer binders.
What is the workability of geopolymer?
It was found that the increase in molarity decreases workability of geopolymer concrete. Also, the workability increases with increase in fly ash (FA) content and AAS/FA ratio in geopolymer concrete. Compressive and split tensile strengths decrease with increase in fly ash content.
