Ground granulated blast furnace slag, also known as GGBS, is growing increasingly popular to produce concrete and ensure sustainable construction. The procurement and engineering team should ask the right questions regarding where to buy the GGBS, how it works and how to use it more efficiently.
Whether you are buying from the GGBS supplier in Maharashtra for the first time or want to optimize the performance of the concrete, here are all the answers to the frequently asked questions regarding purchasing or using GGBS.
· What is GGBS and how does it differ from GBFS?
Granulated blast furnace slag or GBFS is a by-product of iron and steel manufacturing while GGBS is the finely powdered version of GBFS. GBFS is the granular material that can be rapidly cooled from molten slag and GGBS is created by drying and grinding GBFS into fine cement like powder. GGBS can be used to replace ordinary Portland cement (OPC). You can improve the durability and significantly lower carbon footprint within concrete mixes with GGBS.
· What are the advantages of adding GGBS in your concrete mix?
There are several key benefits of adding GGBS to your concrete mix according to GGBS supplier in Rajasthan. It can increase the lifespan and durability with concrete structures. Moreover, it can increase the resistance to sulfate and chloride attack, which makes it ideal for marine or underground structures. It can reduce the chances of thermal cracking while lowering hydration heat while improving workability and finish. It also ensures reduced carbon emissions in the cement-like products. Infrastructure projects like bridges, tunnels and marine ports can use GGBS to attain these benefits.
· How much GGBS should I use in concrete mix?
The amount of GGBS that you can replace varies according to the different projects as per the GGBS supplier in Maharashtra. For general construction, you can use about 30-50% GGBS while you can increase the ratio up to 70% for mass concrete or sulfate resistant applications. In case of precast elements that can increase the concrete strength, you can add about 15-25% GGBS. When you use it in higher proportions, you can increase the durability and sustainability of the product while reducing the early age strength. The dosage should depend on the performance needs of the project while optimizing it regularly.
· Will GGBS impact the strength or setting time of the concrete?
Yes, GGBS can increase the setting time, especially during cold weather or in high replacement level. You can manage this by adjusting the admixtures or by using warm water inside the mix. It can also be improved by accelerating the curing. GGBS concrete shows slow early strength gain against OPC. At the same time, it also outperforms in long-term strength helping concrete reach compressive strengths in 28 to 90 days.
· Is GGBS compatible with SCM and admixtures?
Yes, GGBS is used with all the other supplementary cementitious materials like fly ash and silica fume along with chemical admixtures. You can confirm the strength and compatibility along with the performance in the trial mixes itself. These interactions can impact the setting time and final strength of the mixes according to the GGBS supplier in Rajasthan.
