In this paper the production methods for silica fume and geosilica are outlined to show how each industry provides a quality assured product. The physical and chemical properties of each product are outlined. Concrete properties, including compressive strength, chloride diffusion, resistivity, bleed and sulphate resistance are detailed. Differences between the performances of the two materials are related to their chemical and physical properties.

This paper provides an overview of the performance characteristics of FRS and how the various shotcrete guides specify its use. Practical experiences of the use of FRS in Australia and Canada, in various applications and ground conditions, are combined with existing empirically-based ground support design methods in order to develop a ground support guideline that incorporates the concept of toughness. An assessment of structural synthetic fibres shows that their low modulus makes their performance characteristics different to steel fibres such that they are not likely to be economic in linings where crack widths are limited but preferable where large deflections are permissible

In this paper the production methods for CSF and Geosilica are outlined to show how each industry provides a quality assured product. The physical and chemical properties of each product are outlined. Concrete properties, including compressive strength, chloride diffusion, resistivity, bleed and sulphate resistance are detailed. Differences between the performances of the two materials are related to their chemical and physical properties.

This paper highlights the properties and uses of two types of specialty cements. One of these, microcement, is a relatively new material but is already widely replacing chemical grouts in many rock and soil consolidation contracts. The second, CAC (CAC), has a chequered history but is presently enjoying resurgence in its use due to a better understanding of its limitations and advantages.
