TL;DR: In this article, the degree of reaction of slag in blended pastes is measured using a combination of Selective dissolution and differential scanning calorimetry, but the absolute heat of hydration or contribution to chemical shrinkage of any particular slag is not known.

TL;DR: The performance of mould fluxes in providing the optimum levels of lubrication and horizontal heat flux is relatively simple since they rely on only three properties, the viscosity and break temperature of the flux and the crystalline fraction developed in the slag film as mentioned in this paper.
Abstract: The performance of mould fluxes in providing the optimum levels of lubrication and horizontal heat flux is relatively simple since they rely on only three properties, the viscosity and break temperature of the flux and the crystalline fraction developed in the slag film. These parameters can be readily calculated according to the mould dimensions, casting conditions and steel grade. It is only when the flux is used to combat other problems, such as those arising from turbulent metal flow (e.g. slag entrapment) that flux behaviour becomes complex and more difficult to understand. Some recent developments may help to combat problems associated with turbulent metal flow and free the flux to carry out its principal duties of providing optimum lubrication and horizontal heat flux.

TL;DR: In this paper, slag was utilized as an additive for fly ash-based geopolymers in order to increase the compressive strength of the geopolymer, and the results showed that the addition of slag could generate amorphous products and accelerate the reaction rate of raw materials.
Abstract: Slag was utilized as an additive for fly ash-based geopolymers in this study. It was found that the incorporation of slag could significantly increase the compressive strength of the geopolymer. The compressive strength of geopolymer with 4.0% slag reached 50 and 70 MPa when cured for 14 days at 30 and 70°C , respectively. The mechanism of slag as additive on the enhancement of compressive strength of geopolymer was investigated using X-ray diffractometer (XRD), Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), and mercury intrusion porosimetry (MIP). The XRD and FTIR results showed that the addition of slag could generate more amorphous products and accelerate the reaction rate of raw materials. From XPS results, the decrease of binding energy and a broadening of peaks were observed for Si 2p , Al 2p , and O 1s elements due to the Ca2+ provided by slag. The decrease in binding energy was more favorable to zeolite formation. The results of MIP suggested that the 4% sl...
