What are the uses of GGBS cement?
GGBS cement can be added to concrete along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a o...
Technical and economical feasibility of using GGBS in long ...
benefit from using GGBS to replace CEM I in concrete, except for its thermal advantages. 2. Objectives. It is a common assumption that GGBS concrete lacks sufficient strength at an early age and this might prevent its insitu concrete appliions. It is therefore useful to encourage the appliion of
Portland cement replacement
1990s. In readymixed concrete, GGBS has been used as an addition at the mixer since the 1960s, as has fly ash since the late 1980s. Currently well over half of all UK readymixed concrete contains GGBS or fly ash added at the concrete batching plant to produce a mixer combination. Nowadays, bagged cement is frequently a blend with
Ground Granulated Blast Furnace Slag (GGBS) | Chemical ...
09/05/2018 · Ground Granulated Blast Furnace Slag concrete. GGBS hardens very slowly so it is generally used along with ordinary Portland cement in concrete. A typical combination is 50% GGBS and 50% ordinary Portland cement. But percentages of 20 to 80 are commonly used. Greater the percentage of GGBS, greater will be the effect of GGBS in concrete.

Study Report on Concrete with replacement of Cement by GGBS
09/09/2017 · The initial setting time of concrete is dependent on the concrete's constituents, curing conditions and its appliion use. Concrete with up to 30% GGBS will exhibit 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 one to two hours and for concrete ...
Geopolymer Concrete using GGBS with Partial Replacement of ...
Geopolymer concrete has yet to enter the mainstream of concrete construction. Most appliions to date have been in the precast industry using accelerated curing. However, the use of geopolymer concrete in ready mixed appliions is increasing; building on
Conventional Concrete Over Geo Polymer Concrete Using GGBS ...
A few studies have been reported on the use of such GPCs f or structural experimental investigation was carried out to study the material and mixture proportions the manufacturing processes, the fresh and hardened state characteristics of fly ash based geo polymer concrete are evaluated.

Setting Times The initial setting time of concrete is dependent on the concrete's constituents, curing conditions and its appliion use. Concrete with up to 30% GGBS will ...
Concrete: Cement Substitutes
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.
