Storing up Problems? Methods and Benefits of Quantifying the Effects of Storage on Cement Flow Properties

This article considers the mechanisms associated with powder consolidation and presents experimental data contrasting the caking behaviour of two commercial cements. The results demonstrate the utility of dynamic powder characterisation in differentiating the sensitivity to storage conditions of closely equivalent products.

Optimising the Flow Properties of Cement Powders by Surface Treatment

Surface treatment offers the opportunity to alter the flow properties of a powder in order to optimise process performance. However, a method of quantifying the influence of the treatment is required, to ensure that flow properties have been optimised without compromising other aspects of performance.

Powder Testing Strategies

The properties of alternative cement constituents used in clinker substitution vary markedly depending on their source, and different processing conditions are applied to ensure their successful incorporation to form a product that meets well-defined specifications. The industry has an ongoing need to refine and optimise processes to ensure a consistent product output despite changing feedstocks.
