Evaluation of the performance of ­multi‑component­ cements

Multi-component cements (“CEM X”) do not differ in their behaviour and performance in concrete from those cements already defined in the cement standards. Their constituents are well known and have been used successfully for a long time. Only the composition has not yet been covered by the cement standards.

1 Introduction

Portland cement clinker is the well-tried main constituent of hydraulic cements that are widely used in concrete and mortar. The use of other cement components with, for example, latent hydraulic or pozzolanic properties as a supplement to the clinker has a long tradition in many markets. Portland-composite cements, such as Portland-slag cement or Portland-limestone cement, and blast furnace cements have been standard cements for decades [1]. The majority of these cements contain, in addition to clinker, only one other main constituent, such as granulated blast furnace slag, fly...
