Читать далееOct 1, 2024 · GGBS played a crucial role in improving the bonding between the GGBS and FA phases and the GP matrix and RA, along with promoting a denser microstructure. Furthermore, the hydrate gels of GGBS helped mitigate negative effects caused by pure FA. ... Building materials' EE, measured in MJ/kg or MJ/m³, is influenced by several factors including ...
Читать далееGGBS (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).
Читать далееJul 1, 2015 · Recently, reactive magnesia (MgO) was shown to be a novel GGBS activator for soil stabilisation (Yi et al., 2014). Reactive MgO is generally calcinated from magnesite (MgCO 3) at a lower temperature (~ 700–800 °C) than dead burned MgO (> 1400 °C), and hydrates more rapid (Al-Tabbaa, 2013). Compared to PC, less energy is required for manufacturing reactive MgO …
May 1, 2010 · The EE of a typical 30 MPa concrete mix in Ireland is calculated to be 1.08 MJ/kg. Notably cement is credited with 68% of the total EE. ... The first uses Ordinary Portland Cement, while the second uses GGBS replacing half of the cement content. As expected, the EE of the GGBS mix is significantly lower (30%) than that of its counterpart ...
Читать далееJun 13, 2019 · In this paper, details and results of experimental and predictive studies carried out to determine the mechanical properties of Aluminosilicate materials like Ground Granulated Blast furnace Slag (GGBS) and Fly Ash (FA) based geopolymer concrete specimens are presented and discussed. The major parameters considered in the experimental study are the percentages of …

Читать далее4 days ago · Commonly known as 'GGBS'Regen is Ground Granulated Blast furnace Slag, commonly known as ‘GGBS’.It is a cement substitute, manufactured from a by-product of the iron-making industry.Using one tonne of Regen in concrete reduces the embodied CO2 by around 850kg, compared to using one tonne of Portland Cement. It also increases the concrete’s …
Читать далееThe specific gravity, specific surface, GGBS’s chemical composition and impact of GGBS on water absorption were discussed in this study. Replacing GGBS in concrete production reduced the highest point heat of hydration rate and time. The use of GGBS as a partial cement substitute in the range of 30% to 60% developed strength at longer
