Effect of Curing Conditions on the Performance of Geopolymer Concrete Based on Granulated Blast Furnace Slag and Metakaolin

, 2021
This study aims to evaluate the performance of granulated blast furnace slag (GBFS) and metakaolin (MK)-based geopolymer concrete (GC) under different curing conditions.

Structural aspects of blast furnace slag

Emerging Materials Research, 2013
Interdependence of structure and viscosity of blast furnace slag is discussed based on the available literature. Emphasis is given to both, bridging tendency and network breaking/modifying tendency of the constituents. It is clearly pointed out that slag viscosity cannot be explained only by depolymerization through an increase in basicity, despite ...

Ground Granulated Blast Furnace Slag

2011
Ground 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.

Viscosity of blast furnace type slags

Metallurgical and Materials Transactions B, 2003
The effect of MgO, TiO2, or Fe2O3 on the viscosity of 40CaO-40SiO2-20Al2O3 (mass pct) slags has been measured by the rotating crucible viscometer. Viscosity of these quaternary slags decreased with an increase in the content of additive oxide. At the same content of additive oxide, the viscosity decreases from MgO, TiO2 to Fe2O3.

Granulated Blast Furnace Slag

2013
Metallurgical industry produces slag as by-products. Iron blast furnace slag is the major non-metallic product consisting of silicates and aluminosilicates of calcium. They are formed either in glassy texture used as a cementitious materials or in crystalline forms used as aggregates. Other slags such as copper slag have pozzolanic properties and react

Blast-furnace slag hydration. Surface analysis

Cement and Concrete Research, 1983
Abstract X-ray photoelectron spectrometry (XPS) was used to determine the variation of the characteristic ratios Ca/Si, Al/Si and Mg/Si of two different slags (one in granulated, the other in pelletized form) during hydration. The results show that the slag surface is modified as soon as it becomes in contact with water or alkaline solution.
