HC Deb 02 April 1946 vol 421 c1099
45. Mr. William Shepherd

asked the Lord President of the Council what tests have been made of the M-L brick which is produced from fly ash.

Mr. Herbert Morrison

The results were discussed with the promoters, and arrangements have recently been made for a further series of tests to be made on an improved material.
