SD1:2005 part A Draft 1 v14 : 16/2/051 part A: IntroductionA1. The problem of chemical attackChemical agents that are destructive to concrete maybe found in the ground. In the UK, sulfates and acids,naturally occurring in soil and groundwater, are theagents most likely to attack concrete. The effects canbe serious (see Figure A1) resulting in expansion andsoftening of the concrete to a mush. A substantialnumber of other substances are known to beaggressive, most resulting from activities of man, butcollectively these are a lesser problem as they areencountered only rarely by concrete in the has been standard practice in the UK for at least sixdecades to design concrete for installation in theground to be resistant to attack from commonly foundchemicals, including sulfates and acids. BRE haveunderpinned this approach by issuing a series ofguidance notes and Digests, dating back to 1939, onthe causes of chemical attack and how to specifychemically resistant , the large majority of concrete installedin the ground has performed entirely satisfactorily andis expected to do so for its required working , however, cases of chemical attack havecome to light and have been subject to research byBRE and others.
