Durability Properties and Microstructure of Ground Granulated …
2014520;The characteristic of GGBS was examined using particle size analyzer, X-ray diffraction (XRD) and chemical analysis tests. Table 1 shows the physical and chemical properties, whereas Figs. 1 and 2 show the particle size distribution and XRD test result of the GGBS respectively. The average particle size of GGBS was 9.2 μm compared to …
The efficient use of GGBS in reducing global emissions
Concrete buyers and specifiers should recognise these issues and decide how best to align their ambitions to reduce emissions both on-site and globally. GGBS is an excellent …
The Engineer''s Blog - What is GGBS? Why its using in concrete?
GGBS Quantity = (0.5 * 300 kg) / (1 + 0.5) = 150 kg. So, the concrete mix would contain 150 kg of GGBS and 150 kg of cement. Note: The replacement level of GGBS in concrete may vary depending on the specific requirements of the project, the strength and durability specifications, and the local regulations. It’s recommended to consult with a
New report finds that Ground Granulated Blast Furnace Slag will …
919;GGBS’s use to reduce greenhouse gas (GHG) emissions in concrete needs to be carefully considered. A group of 13 experts from across structural engineering, concrete and cement industries, construction, academia, and civil society have collaborated on a paper that reviews the use of ground granulated blast furnace slag (GGBS) in …

Ground granulated blast-furnace slag ( GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, …
Enabling sustainable rapid construction with high volume GGBS …
11;For all of the mixes containing GGBS, when cured at 30 °C, the cross-over effect was delayed even later than 56 days after casting, which is a considerable improvement when compared to the 7-day of PC47. GGBS concretes cured under adiabatic conditions showed also better improvements in compressive strength at early ages than …
A Case Study in Hong Kong – High-performance Low-carbon …
project and its comparison with PFA concrete. Strength development of OPC (100% OPC), PFA (25%) and GGBS (50%) concrete (W/C ratio 0.40): 7-day to 28-day strength ratios …
A Review: GGBS as a Cement Replacement in Concrete
51;The specific gravity, specific surface, GGBS''s chemical composition and impact of GGBS on water absorption were discussed in this study. Replacing GGBS in concrete production reduced the highest point heat of hydration rate and time. The use of GGBS as a partial cement substitute in the range of 30% to 60% developed strength at …
