 · The resistance of CS–GGBS stabilised clay to sodium sulfate attack was lower than that of MgO–GGBS stabilised clay, but higher than that of Portland cement stabilised clay. Unlike CS–GGBS stabilised clay, there was no calcium aluminate hydrate or alumino-ferrite monosulfate produced in MgO–GGBS stabilised clay, and hence no ettringite ...

Ground granulated blastfurnace slag (ggbs) is usually the only constituent of concrete that contains appreciable quantities of sulfide. The sulfide content of the concrete can be determined, and if the sulfide content of the ggbs used in the manufacture of the concrete is known, the ggbs content of the concrete can be calculated.

Typically the 7-day strength of a ggbs concrete will be 55-65% of the 28-day strength compared to 70-80% for a similar CEM I Portland cement concrete. The reduction in early-strength will be more noticeable at high GGBS levels and low temperatures. Similarly low cement content concrete, kerb backing etc, the reduction will be magnified.

 · Reactive magnesia (MgO) was used as an alkali activator for ground granulated blast-furnace slag (GGBS) and its activating efficiency was investigated compared with hydrated lime.

 · The replacement of cement by GGBS successfully compensated the 30 wt% lower cement content and generated additional C-S-H gel through the spontaneous hydration reaction in 28 d. The mass loss due to CH dehydration decreased from 3.5% (corresponding to 14.2% CH) in 30BC to 1.7% (corresponding to 6.9% CH) for 30BC-SF …

An investigation is made to explore the efficacy of fly ash-slag (FA-GGBS) geopolymer in stabilizing granular soil through a set of experimental studies. The experimental program focused on compaction characteristics, unconfined compressive strength, bearing resistance, and durability of geopolymer stabilized granular soil to assess its ...

Green and Gracious Builder Scheme. The Green and Gracious Builder Scheme (GGBS) was introduced in 2009 to raise the environmental consciousness and professionalism of builders. It is also a benchmark of a builder's corporate social responsibility to the environment and public during the construction of projects. It aims to:

Abstract: The paper investigated the effect of locally sourced fly ash and ground granulated blast-furnace slag (GGBS) on the compressive strength and chloride resistance of concrete. The mix proportion was cementitious material (total of ordinary Portland cement (OPC), fly ash and GGBS): sand: coarse aggregate: water of 1:2:3:0.6 in which 20% ...

– GGBS is a slag waste product from steel plants, which is subsequently processed. Around 11 Mt of GGBS is produced per annum and the entire quantity is fully utilized in the cement industry (for manufacturing slag cement, PSC), or used at batching plant long with OPC.

 · GGBS concrete (Global Resources-INDIA) It is a by-product from the blast furnace which is used to make iron. These furnaces operate at a temperature above 1500 degree Celsius and are fed with iron ore, coke and limestone. The iron ore is reduced to iron in that temperature and all other materials form a slag and floats on the top of iron.
