Strength development of solely ground granulated blast furnace slag geopolymers

Construction and Building Materials, 2020
Abstract 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, 2004
Granulated 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, 1999
Ground 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, 2000
This 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, 2006
Ground 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.

Alkali activated ground granulated blast-furnace slag concrete: Preliminary investigation

Cement and Concrete Research, 1991
Abstract This report presents results of a preliminary investigation dealing with the compressive strength development of alkali activated ground granulated blast-furnace slag concretes. These concretes incorporated sodium silicate as an activator but did not contain any portland cement.

Carbonation/granulation of mine tailings using a MgO/ground-granule blast-furnace-slag binder

Journal of Hazardous Materials, 2019
A carbonation/granulation process for treating mine tailings using a MgO/ground-granule blast-furnace-slag (GGBS) binder was developed. The materials were mixed and granules produced using a granulator, then the granules were cured in a CO2 atmosphere. The optimum granulator rotation speed and retention time were 60 rpm and 7 min, respectively.

Synergistic effects in ground granulated blast furnace slag‒steel slag‐based geopolymer

International Journal of Applied Ceramic Technology
Abstract To promote the efficient and high‐quality use of steel slag (SS), a geopolymer was innovatively developed from ground granulated blast furnace slag (GGBFS) and SS using an optimized alkali equivalent method.

Soil Stabilization using Lime-Activated Ground Granulated Blast Furnace Slag

"SP-178: Sixth CANMET/ACI/JCI Conference: FLy Ash, Silica Fume, Slag & Natural Pozzolans in Concrete", 1998
Soil stabilization with cement or lime is a well established technique for use in highway or foundation construction. Extensive laboratory investigations and a full-scale trial have been carried out to evaluate the performance of ground granulated blast furnace slag (ggbs) in combination with lime, for stabilizing soils.

Properties of alkali-activated ground granulated blast furnace slag blended with ferronickel slag

Construction and Building Materials, 2018
Abstract This study aims to investigate the feasibility of using ferronickel slag (FNS) blended with ground granulated blast furnace slag (GGBS) to produce alkali-activated cements (AACs). Sodium silicate (Na2SiO3) and sodium hydroxide (NaOH) are used to activate the GGBS/FNS blends with mass ratio varying from 100:0 to 40:60.
