In this experimental investigation, five mixes with maximal replacement levels of ordinary Portland cement (OPC) with WPSA and GGBS of up to 50% weight. The …

construction schedules where the quick mount is required. The last phase of the GGBS was shown in the figure 1.1. So far in the literatures most of the work has done in the M30, M40 grade of concrete and very few has covered in the M20 grade of concrete using GGBS. Hence it is worth the experimenting

To help to determine whether this idea has merit, a group of experts drawn from across the concrete and cement industry, construction, academia and civil society undertook a literature review to better understand global production and utilisation of GGBS and clinker, and how this balance could change in the near-future.

Characteristics of GGBS as an Alternate Material in Conventional Concrete Shreyas.K 1 1Asst professor ... as well as in the overall economy of construction projects. This requirement is drawn the attention of investigators to explore new ... granulated blast furnace slag for M25 grade of concrete at various ages. From the study, it can be ...

Calculations Relating to Concrete and Masonry. Sidney M. Levy, in Construction Calculations Manual, 2012 5.4.5 Ground Granulated Blast-Furnace Slag. Although portland blast-furnace slag cement, which is made by intergrinding the granulated slag with portland cement clinker (blended cement), has been used for more than 60 years, the use of …

7-day to 28-day strength ratios of OPC, PFA and GGBS concrete: 0.829, 0.748 and 0.734 respectively. The 28-day strength of GGBS concrete: higher than OPC concrete and …

 — GGBS's use to reduce greenhouse gas (GHG) emissions in concrete needs to be carefully considered. A group of 13 experts from across structural engineering, concrete and cement industries, construction, academia, and civil society have collaborated on a paper that reviews the use of ground granulated blast furnace slag (GGBS) in …

 — The mix design is prepared based on Lloyd and Rangan, assuming density of concrete is 2400 kg/m 3, and the total aggregate is taken as 70%, ((Alkaline/(fly ash + GGBS)) or (A/B)) ratio as 0.3, Mass of (fly ash + GGBS) as 387 kg/m 3, Mass of alkaline liquid (Na 2 SiO 3 + NaOH) as 116 kg/m 3, Mass of NaOH and Na 2 SiO 3 solution as …

The grinding process takes account of mean particle size, grading (particle size distribution), fineness and the particle shape in order to ensure that when used in concrete performance is maximised.
