## 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
Analysis of the operation of a shaft kiln fired with
The cementitious performance of a coarse granulated blast furnace slag, 2900 cm 2 /g, was investigated in concretes of 230, 280 and 330 kg binder/m 3 . First, the slag partially replaced 30%, 50% and 70% of Portland cement, the strength reduced as the amount of slag increased; however, for high bind
