concrete for many applications. Concrete made with GGBS has many advantages, including improved strength [5,6,13,16], durability [3,9,13], workability [1,2,19], economic and environmental benefits [9]. The only drawback in the use of GGBS concrete is that its strength development is considerably slower under the standard

8.3.2 Copper Slag Use in Concrete. Attributed to its low porosity and high hardness, CS could ideally be used as an alternative source to natural sand in concrete applications. Indeed, a great deal of work has been undertaken to study the properties of concrete made with CS, and it is shown that when designed properly, the use of CS can improve ...
Workability Characteristics of Concrete with GGBFS As given by ACI, the replacement of GGBFS will let us use an adequate amount of coarse aggregates without compromising the workability of the concrete. The thickness of the mix can be reduced by this method. A replacement of cement with GGBFS by an amount of 30 to 50 % showed a greater workability.
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, to produce a glassy, granular product that is then dried and ground into a fine powder.Ground-granulated blast furnace slag is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...
Flyash and GGBS replacing of cement in concrete[1]. Geopolymers are formed by alkaline activation of an aluminosilicate material like fly ash, GGBS, metakaolin, rice husk ash, activated bentonite, clay, red mud etc[2]. Effective use of GGBS in geopolymer concrete further reduces the environmental pollution.
From structural point of view, GGBS replacement enhances lower heat of hydration, higher durability and higher resistance to sulphate and chloride attack when compared with normal ordinary concrete. On the other hand, it also contributes to environmental protection because it minimizes the use of cement during the production of concrete. However, it is identified that […]
concrete mixed with GGBS exhibited lower diffusion coefficient compared to GGBS free concrete. GGBS with 40% & more performs better. Oner A Akyuz S (2007) investigated to find the optimum level of optimum level of ground granulated blast-furnace slag (GGBS) on the compressive strength of concrete. Test concretes were
Oct 03, 2020· The initial setting time of concrete is dependent on the concrete's constituents, curing conditions, and application use. Concrete with up to 30% GGBS will exhibit a similar initial setting as concrete with Portland cement only. At replacement levels of 40% to 50% the initial set is likely to be extended by 1 to 2 hours and for concrete ...

ICSECT 141-1. The main study of the objective to achieve information about effect of SCMs on concrete mixes. In this study using
May 26, 2016· Novelty in project • GGBS is byproduct of aluminium industry though application of GGBS will be important factor to reduce overall cost of concrete. • It encompasses enviromental,economic and social dimentions, the responsible management of resources we use in construction and perticularly concrete production in india being the second ...
Sep 14, 2019· In PSC cement manufacturing, GGBS added should not be less than 25% and should not be more than 70%. Compressive strength of Portland Slag Cement should not be less than 33 Mpa, means PSC available in 33 grade (there are no specification for higher grades of PSC) So according to IS code you can replace portland cement up to 70% by using GGBS.
GGBS concrete mixes do however tend to have a higher ultimate strength than Portland cement mixes though it can take several months for GGBS concrete mixes to overtake Portland cement mixes which gain strength more quickly. This can limit the use of GGBS in concrete for some applications where early strength is important.
Geopolymer concrete has yet to enter the mainstream of concrete construction. Most applications to date have been in the precast industry using accelerated curing. However, the use of geopolymer concrete in ready mixed applications is increasing; building on

Strength gain in GGBS concrete. With the same cementitious material content (the total weight of Portland cement CEM I plus GGBS), similar 28-day strengths to Portland cement CEM I will normally be achieved when using up to 50% GGBS. At higher GGBS percentages the cementitious content will need to be increased to achieve equivalent 28-day strength.
