The use of Glass Fibre-Reinforced Polymer (GFRP) bars for internally reinforcing concrete structures has been growing to overcome common problems of steel reinforcement, such as corrosion. Areas for application are dominated by bridge decks where de-icing salts are used, although other applications include coastal structures or structures aiming for an extended design life.

Protimeter Revisited for Large Scale Damp Investigations By: Dr ANTHEA AIREY BSc(Hons) PhD MBA MRACI CChem – Project Leader, Scientific Services – Airey Taylor Consulting Summary: Damp in structures precedes eventual rusting. “Protimeter Survey-master” is a non- destructive testing instrument favoured by building inspectors assessing bathroom leaks and the like. The Protimeter measures the reflected radio…

A “green” philosophical learning point is to harness and enhance natural responses to structures as part of the design and construct approach. An original engineering design system is explored that looks to the environment to identify key responses involved in placing concrete slab foundations on reactive clay soils.
