Abstract

1474911 Moulding lightweight concrete C W B URMSTOM 29 July 1974 [30 April 1973] 20505/73 Addition to 1330458 Heading B5A [Also in Division C1] Lightweight concrete is moulded by the process described and claimed in the parent Application, but using an aggregate comprising pumice. Fine or coarse pumice of (10-35) lb./cu. ft. density is used in the concrete mixture, which is cast and aerated in a mould 1 having removable partitions 5. The lid 6 comprises bolted-together channel strips 7 reinforced by bolted-on channel strips 10. The strips include circular and elongate apertures 14 internally covered by filter paper or cloth, and the lid is clamped to the mould walls by catches 22 and lugs 21.
