Cob light clay straw compressionDuane/Dorothy Lindstrom cboy at newnorth.netMon Feb 8 16:00:36 CST 1999
I am attempting to do some cost estimating for the use of light clay (90% straw/10% clay) for infill walls. Does anyone know approximately how much finished light clay (by volume) one can expect from a normal 12 cubic foot, 3 string bale of straw? I realize the bale is compressed and will have a larger volume as loose straw but I also understand that the finished light clay must be tamped (compressed) to some extent within the lay-up forms. Has anyone seen some sort of conversion factor for this or know by experience the approximate cubic footage of wall which can be produced by a cubic foot of baled straw?
