TACKLING THAUMASITE attack will be the topic of a series of BRE seminars that will tour the country in the coming months.
The events, part sponsored by the Department of Trade & Industry and hosted by ICE local associations, aim to introduce construction professionals to the new BRE Special Digest SD1.
SD1 has been prepared to combat the problem of thaumasite sulphate attack (TSA).
TSA was first discovered in 1998 on bridges on the M5 in Gloucestershire.
Key factors triggering the attack have been provisionally identified as the use of limestone aggregates, the presence of high levels of sulphates in the backfill around the foundations and a wet, cold environment.
BRE believes its publication will be significant as SD1 (in parallel with Amendments to BS 5328: Concrete) will become a de-facto standard for specification of all concrete to be used in the ground.
Around 20 half-day seminars will be held in total, including two in Scotland (NCE 9/16 August) and an all-day seminar at the BRE on 13 November. The first ICE hosted event will be for the Northern Association Cumbria Branch on 27 September.
