The benefits of using GGBS in cement concrete as a mineral filler 15% gave the better results compared to the other proportions (0%, 5%, 10%).The study indicates the possibility of using GGBS as filler in cement concrete. Keywords: Concrete, M-sand, Ground Granulated Blast furnace Slag (GGBS), Compressive strength, Split ensile strength

Another major hurdle of extensive use of GGBS concrete lies in the little source of supply of GGBS. As Hong Kong is not a major producer of steel, GGBS as a by-product of steel has to be imported overseas and this introduces higher material cost due to transportation and the supply of GGBS is unstable and unsteady. This question is taken from book named – A Self Learning Manual – Mastering ...

GGBS cement can be added to concrete in the concrete manufacturer's batching plant, 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 one-to-one basis by weight.

2010-05-28 If your mix design assumes you’ll be using aggregates in a saturated surface dry state, but the aggregates you actually use are dryer than SSD, they will absorb mix water. Dry aggregates can also absorb any liquid admixtures in the mix, which can greatly reduce their effectiveness. Similarly, if your aggregates are wet, they will add water to your mix, resulting in greater slump and greater ...

One, proper mix proportions using the optimum cement content will yield a dense, impervious and relatively unabsorbent concrete. Two, the optimum concrete is 6 and one half to 7 and one half sacks per cubic yard and the water/cement ratio should not exceed 6 gallons per sack of cement to produce a mix that is plastic and workable. Three, reinforcing steel must have a minimum of 3 inches of ...
