HC Deb 27 May 1976 vol 912 cc313-4W
Mr. Rooker

asked the Secretary of State for the Environment if he has completed his consideration of amendment to the building regulations regarding the use of calcium chloride as a setting agent in reinforced concrete; and if he will make a statement.

Mr. Freeson

We are still awaiting the outcome of the British Standards Institution Committee's consideration of this matter. It is not yet clear whether sufficient grounds exist for recommending that calcium chloride should not be used on concrete containing embedded metal.
