asked the Secretary of State for the Environment whether he will place in the Library of the House a copy of the architect's report on the problems of high alumina cement in the office building at Washington, County Durham, that is causing delay in the introduction of the family endowment scheme.

In the light of the advice issued by my Department about the structural use of HAC concrete, it was considered prudent to strengthen parts of the building at Washington, Co. Durham, and this has delayed its completion. Copies of the letters issued by my Department about HAC concrete are being placed in the Library.
