Effects of combined usage of GGBS and fly ash on

Ground granulated blast furnace slag (GGBS) and fly ash combination based geopolymeric recycled aggregates concretes (GRAC) were prepared as a substitution of normal concrete in order to reduce the consumption of ordinary Portland cement and natural aggregates as well as to make use of demolished waste concrete.

Mechanical Properties of Geopolymer Concrete with Alternative

Recycled aggregates (RA) are produced from crushing the concrete waste of demolished buildings to a required size. A study has revealed that, compressive strength of geopolymer concrete increases with increase in concentration of sodium hydroxide in terms of molarity, sodium silicate to sodium hydroxide ratio, curing temperature and curing time.

1 INTRODUCTION IJSER

to concrete strength, concrete made with GGBFS continues to gain strength overtime, and has been shown to double its 28-strength -day over periods of 10 to 12 years. Our project is a testing project compared with the compressive strength of PCC and GGBFS, used concrete. Here the amount of cement is reduced and that amount is replaced with GGBS.

PDF Ground Granulated Blast Furnace Slag Conclusion

Compared to concrete produced with only OPC, the GGBS blend produced concrete tend to have a slightly higher tensile strength and elastic modulus for a given compressive strength. Generally, GGBS makes it easier to achieve a good surface finish. In addition the colour of concrete will be lighter than concrete produced with only OPC. Durability ...

Ground Granulated Blast Furnace Slag (GGBS) | Chemical

Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine aggregate and coarse ...
