A technical lecture on Reinforced Autoclaved Aerated Concrete.

RAAC provides a lightweight thermally insulating construction material. It was mainly used in flat roof panels, but has cropped up in pitched roofs, wall panels, both load bearing and non-load bearing, and floors. UK use was typically between 1960 and 1985. It hasn’t aged well.

It doesn’t behave like reinforced concrete and has resulted in a number of issues, involving excessive deflections and a SCOSS alert due to a collapsed roof in a school plus a widespread inspection and propping programme and a research programme.

This presentation provides an overview of the material, the problems and an update on the current research.


Speaker

Dr Chris Atkins, Technical Principal at Mott MacDonald
Chris is a Technical Principal at Mott MacDonald working in the Materials and Corrosion Technology Team. His career has been based around the deterioration of construction materials, from rusting steel and reinforcement, to acid attack of concrete in high temperature flues, from modelling deterioration, developing specifications to try and achieve durability, to investigation, repair, and life extension. 

His first degree was in Civil Engineering, he has a PhD in Corrosion, is a Fellow of the Institution of Civil Engineers, and a Fellow of the Institute of Corrosion. He is a member of the I Struct E Study group on RAAC.
