The paper speculates upon the molecular relaxation and dissipation mechanisms which may be responsible for the interface Theological characteristics of thin organic films. The molecular structure and interface rheology of a homologous series of poly(n-alkyl methacrylate)s are characterised for this purpose. These Theological properties are identified by the measurement of the interface shear strength, t as a function of the contact pressure. The molecular structure is deduced using vibrational spectroscopy. The Eyring model for molecular plastic flow is then applied and a correlation is drawn between the Theological and structural properties which are discussed in terms of possible mechanisms for the dissipation of the frictional energy. © 1994, Elsevier Inc.

Specifications relating to concrete durability have been emphasised in many recent codes of practice governing the design of concrete structures. Typical examples of this trend are noted in Australian Standard AS 3600, British Standard BS 8110 and a Guide to Durable Concrete reported by ACI Committee 201. Apart from the requirements of higher strength grades to ensure required minimum water: Cement ratios for aggressive environment exposures, some advantages offered by the use of blended cements have been recognised in these documents. The use of blended slag and fly ash cements is increasing worldwide and specific information on the long-term performance of such concretes in high chloride environments is needed. This paper presents data on the long-term corrosion characteristics in high chloride environments of reinforcement within a series of concretes individually incorporating a high C3A ordinary portland cement, a low C3A cement, a slag blended cement and an ASTM Class F fly ash blended cement. The concrete performance has been assessed using electrochemical monitoring of corrosion of the embedded reinforcement by potentiodynarnic anodic polarisation and the concrete resistivity. Factors that significantly influence the corrosion rate of the reinforcement include the concrete water: Binder ratio, the binder type and the resistivity. Comments are made regarding current North American, British and Australian specifications for concrete under marine service conditions. From the data presented, the specification for long-term durability of concrete for marine conditions could be based on concrete resistivity with a suggested limit of around 5000 ohm cm at 28 days.
