The paper by Douglas and Zerbino is of interest as it describes another technique to characterise the reaction between blast furnace slag and portland cement. The efficacy of the technique has been studied at the National Building Technology Centre using the same type of calorimeter. As indicated by

β¦ Synopsis
The objective of this study is the characterization of slags from different sources by their chemical composition, glass content, rate and total heat of hydration and compressive strength development with a vlew to establish a relationship between some of their properties and compressive strength.
Binders incorporating 50 per cent slag present the same classification derived from total heat evolved as from slag activity indexes.

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. The five concrete m
Specific surface areas and pore structure studies were carried out on autoclaved slag-lime and slag-quartz-lime pastes. Autoclaving temperatures were 181 and 213Β°C. Water and nitrogen adsorption isotherms were measured and their results are comparatively discussed. The specific surface areas measure
The hydration behaviour of a 1:1 mixture (by mass) of 'Secar 71' refractory aluminous cement and ground granulated blast furnace slag has been studied over a range of temperature using conduction calorimetry, x-ray diffraction and thermal analysis techniques. The initial hydration of the cement pro
## Abstract One method proposed for utilisation of highβmagnesia Portland cements involves the addition of active siliceous admixtures such as fly ash or ground granulated blastfurnace slag. This addition enables otherwise unsound cements to pass the ASTM autoclave test (C151β74a) for expansion of
Methods for determining the codtent of blast furnace slag (BFS) in blended cements composed of BFS and OPC have been briefly reviewed. A variety of dissolution orocedures were investigated and the results compared critically. Extractions with methanol-salicyclic and/or acetic acid show that these s
