I believe the correct name for this technique is "leichtlehmbau", also known as leichtlehm, light-clay or straw-clay. It is NOT a cob mixture. Basically it is straw given a very light coating of clay slip, mixed thoroughly, allowed to dry almost completely (until just barely tacky), and then rammed into forms to make panels, or stuffed into walls as insulation. Robert Laporte is probably one of the best known proponents of this technique in the USA, and has a more detailed description of the technique in his book "MoosePrints". You can order this booklet by going to: www.strawbalecentral.com click on their "books and videos" link, and you will find it listed in it's own section "Light-Clay and Timber Framing". The price listed today is $12. You can also find more information in the coblist archives by searching on some of the above terms.
