To promote the large-scale recycling of solid waste, the hydration characteristics of blended cement with different amounts of GGBS (ground granulated blast-furnace slag) and SS (steel slag) were investigated. The optimum blending amounts of GGBS and SS in cement were 40% and 10% by mass, and the optimum dosage of Na2SO4 in the C50-S40-SS10 …

3.2 Series 2, Mixes with GGBS. In series 2, GGBS was used as partial replacement of cement. Total 11 numbers of trial mix with replacement of GGBS ranging between 10 and 70% namely M1G2C to M11G2C without altering the W/C ratio, i.e., 0.85. Table 7 gives the result of compressive strength, water absorption and block density of the series 2 with ...
In the production of ready-mixed concrete, GGBS replaces a substantial portion of the Portland cement component, generally about 60-70%. Trivia. Used on its own, GGBS …
Given the importance of GGBS from a technical perspective, it is proposed that its use should be focused on these technical benefits, rather than as a low-carbon cement replacement. This, along with likely future supply issues, illustrates the urgency of moving past our dependency on GGBS and focusing on alternatives such as calcined clays ...
Very occasionally, it can be found up to a ratio of 90% GGBS and 10% Pc. Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume
Ground granulated blast furnace slag (GGBS) is a by product obtained from iron and steel industries, useful in the design and development of high quality cement paste/mortar and concrete. This paper investigates the applicability of relevance vector machine (RVM) based regression model to predict the compressive strength of various GGBS based concrete …
Introduction. Ground granulated blastfurnace slag (GGBS) is a hydraulic binder, i.e. a cement, which has been known and used for 150 years. It improves the quality and durability of concrete, and its production is virtually CO 2-free.Yet its many advantages in producing sustainable, high-quality concrete remain underappreciated and underused.
GGBS, or Ground Granulated Blast Furnace Slag, is a byproduct of the iron and steel industry that is used as a supplementary cementitious material in concrete. GGBS is produced by quenching molten slag from a blast furnace with water and then grinding the resulting material into a fine powder. This process creates a material with cementitious ...
Ground Granulated Blast Furnace Slag (GGBFS) is a by-product from the manufacture of Iron and a high-performance substitute to traditional cement that will rise the technical …
GGBS can be used as a replacement for cement because it contains the same oxides (see table 1) and undergoes the same hydration process. Additionally, the GGBS reacts with the excess calcium hydroxide to form calcium silicate and calcium aluminate hydrates which contribute to filling and blocking the pores within the crystalline structure.
OPC with 66% to 80% GGBS : 12 C25/30 : 0.50 : 340 : OPC with 36% to 55% Fly Ash : 13 ; Blinding Concrete 0.55 : 220 : OPC with 36% to 65% GGBS : 14 Blinding Concrete : 0.55 : 220 : OPC with 26% to 35% Fly Ash : Notes: A. The specifications are basedon the requirements ofBS 8500-1 standard B. The minimum cement/combination content …
During this process GGBS is added into it as per % and grinded with clinker and gypsum. After grinding it is stored in silo and then sent for delivery through bag packs or in bulker as loose cement. % denotes the percentage of total quantity of cement. Example blending it with 70% of GGBS PSC will have 70% GGBS and opc 30% total will some to .
IV. GGBS Concrete GGBS Proportions On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. A typical combination is 50% GGBS with 50% Portland cement, but percentages of GGBS [4] anywhere between 20 and 80 % are commonly used.
GGBS for low carbon concrete production. Our portfolio of innovative, high-quality products includes Ground Granulated Blast Furnace Slag (GGBS), a cement addition providing an optimal mix of environmental benefits and performance. A by-product of the iron industry, GGBS is made when blast furnace slag is finely ground into a powder.
GGBS is an excellent supplementary cementitious material that helps displace clinker demand globally. However, GGBS is a limited and constrained resource that is almost fully utilised globally. Therefore whilst global supplies must continue to be fully utilised, locally increasing GGBS use is unlikely to decrease global emissions.
On its own, GGBS hardens very slowly and for use in concrete, it needs to be activated by combining it with Portland cement, but percentage of GGBS anywhere between 20 and 80 percent are commonly used. The greater the percentage of GGBS, the greater will be the effort on concrete properties.

GGBS (Ground Granulated Blast-Furnace Slag) is an environmentally friendly product, made from a by-product of iron and steel making. This is a high quality, low CO₂ material, CE certified, conforming to BS EN 15167-1:2006. Although not technically a pozzolan, it behaves in the same way as popular pozzolans like PFA (Pulverised Fly/Fuel Ash).
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 ...
