§ Mr. Rooker
asked the Secretary of State for Education and Science if she will make a statement outlining the progress of her Department's Buildings Division inspection of school buildings for improper use of calcium chloride as a faults and defects due to the excessive or setting agency for reinforced concrete, giving details of faults found and estimated cost of repairs.
§ Miss Margaret Jackson
In March 1977 local education authorities and other bodies were asked to make visual and chemical checks on 73 educational buildings where there was a prima facie case for investigation. Reports have been received on 52 of these buildings; in the remaining cases further information is being sought. These reports indicate that 20 schools show some visible signs of damage and/or evidence that calcium72W chloride had been added in the manufacture of prestressed concrete components. In two of these cases, the tests indicate positively the need for repairs because of corrosion in the embedded metal. In the remainder, the need for repairs has not yet been determined. The cost of repair work at the two schools has been estimated at £80,000.
