1946A. F. Boyd Rep. Tests No-Fines Concrete (Commonwealth Exper. Building Station, Sydney) 1 Little technical information was available on the strength of no-fines concrete as applied to building construction. 1954Archit. Rev. CXVI. 410/3 Hills themselves also made no-fines walling blocks about 7 in. thick..for facing their steel⁓framed houses. 1955Times 5 July 17/3 (Advt.), We handed over during the year some 19,500 permanent dwellings, most of them built by the Wimpey ‘No-Fines’ technique, which continues to make a wide appeal to those wanting speed combined with a high standard of construction. 1960M. Bowley Innovations in Building Materials ix. 209 Dense concrete properly made is impervious to moisture..but provides poor heat insulation... ‘No fines’, on the other hand, is more pervious..but provides better heat insulation. 1969E. C. Adams Sci. in Building III. viii. 139 No-fines is made by mixing a coarse aggregate with cement and water. Ibid., No-fines concrete is not subject to capillarity, and can..provide a weatherproof wall in one thickness..if rendered externally. |
