§ Mr. Eadieasked the Minister of Public Building and Works what Government research has been carried out into the development of fly-ash as an additive for binders in the manufacture of cement and for use in other industries.
§ Mr. John SilkinSince the early 1950s the Building Research Station has helped the Central Electricity Generating Board to find the best ways of using pulverised fuel ash in building. I understand that the Road Research Laboratory has also made a contribution. Over 40 per cent. of the ash produced by power stations is now used in the construction industries.
