Historical information
Photograph shows batching concrete by the MMTB prior to the use of truck mounted concrete mixers which delivered the concrete to the worksites. The photo shows workers loading portable boxes of a fixed size and fitted with handles with aggregate or sand and then carrying it over to the loading device for mixing. Along the lower edge of the photograph can be seen a bag of cement which would be split and loaded into the mixer. Workers would then barrow the mixed concrete to the track or worksite being concreted. It was hot dirty labourous work.
