Abstract

1476081 Electrically conductive settable compositions MARCONI CO Ltd 12 Dec 1975 [7 March 1975] 9525/75 Addition to 1456611 Heading ClH [Also in Division B5] A settable composition, as claimed in Specification 1,445,611, prepared ready for setting, is subjected to pressure. The composition may be prepared in a mould of a kind in which pressure may be applied to the contents, or prepared on the ground, a suitable road roller being utilized to provide the pressure. Pressure may be applied during the initial period of setting (e.g. in the form of a series of impacts) following which the composition may be permitted to complete its setting process with pressure removed or with steady pressure still applied. In U.K. Specification No. 1,445,611 is claimed a settable composition, suitable for use as an electrically conductive structural material, comprising a settable bonding material and an aggregate which is composed mainly of one or more electrically conductive particulate carbonaceous materials which form a substantially continuous particle size spectrum including particles of plus 14 B.S. mesh and particles of minus 14 B.S. mesh, some or all of the plus 14 mesh particles having a particle size at least 10 times greater than some or all of the minus 14 mesh particles.
