Carbonated ground granulated blast furnace slag stabilising brown kaolin
Environmental Science and Pollution Research, 2021Proposals have been made by several researchers to conduct the sequestration of carbon dioxide (CO2) through calcium and magnesium-rich materials. From these materials, ground granulated blast furnace slag (GGBS) containing 5% magnesium and 45% calcium is seen to be a good candidate and is available to sequester CO2. This study intends to ascertain the

Ground Granulated Blast-Furnace Slag and its Activation Methods
Materials Science Forum, 2016. The ground granulated slag is a wide spread component of various types of cement and binding substances. Its pozzolanic activity depends on different factors. It is searched out, that there are no minerals able to liquid maturing in the slag under consideration, the slag activity data according to domestic and foreign standards specifies

Ground Granulated Blast Furnace Slag
2011Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.

Hydration of alkali-activated ground granulated blast furnace slag
Journal of Materials Science, 2000The hydration of ground granulated blast furnace slag (GGBFS) at 25 °C in controlled pH environments was investigated during 28 days of hydration. GGBFS was activated by NaOH, and it was found that the rate of reaction depends on the pH of the starting solution. The main product was identified as C-S-H, and, in the pastes with high pH, hydrotalcite was

Strength development of solely ground granulated blast furnace slag geopolymers
Construction and Building Materials, 2020Abstract This paper investigates the strength development of solely ground granulated blast furnace slag geopolymers (GGBFS). An optimal combination of GGBFS with various solid/liquid and alkaline activator ratios had been determined by performing a number of compressive strength tests.

Granulated blast furnace slag used to reduce grounding resistance
IEE Proceedings - Generation, Transmission and Distribution, 2004Granulated blast furnace slag is the residue produced from steel-making plants. Waste utilisation is an attractive alternative to disposal in that disposal cost and potential pollution problems are reduced. Nowadays the use of slag in concrete, either as a constituent of cement or as a mineral admixture, is widespread. The granulated blast furnace slag

Granularity and Surface Structure of Ground Granulated Blast‐Furnace Slags
Journal of the American Ceramic Society, 1999Ground granulated blast‐furnace slags (GGBS) show improved hydration reactivity when granularity fineness increases, but the reason for the improvement in reactivity is still unknown. GGBS specimens with Blaine surface areas of 4680, 6470, and 8050 are analyzed, but the conventional reactivity criteria, such as degree of ...

Autogenous Shrinkage of Ground-Granulated Blast-Furnace Slag Concrete
ACI Materials Journal, 2000This investigation was carried out to study the effects of replacement percentage and fineness of ground granulated blast-furnace slag (GGBFS) on the autogenous shrinkage of high-performance concrete. All the mixtures had the same water-cementitious materials ratio (w/cm = 0.30) and the same volume of binder at 31 % of the total volume of concrete. The

In situ imaging of ground granulated blast furnace slag hydration
Journal of Materials Science, 2006Ground granulated blast furnace slag (GGBFS) reacts with water in the presence of calcium sulfates and alkalis and is frequently used as a partial replacement for portland cement in concrete. The hydration products are known to be slightly different compositionally and morphologically than those of pure portland cement hydration.
