Hi all,

Just an FYI in case you are interested.  I will be testing the material 
properties of the 1:1 sand:cement mix used for seismometer peirs and 
sometimes as a structural member of the device itself.

I will be testing cylinders in a compression test which gives elastic 
modulus and compressive strength directly.  It also gives a good 
estimate of tensile strength and toughness.  The plan is to test one 
batch moist cured for 28 days and one batch air cured for after 7 days 
of moist cure.  Thermal properties will have to wait, as there is still 
a lot of gel in the mix at 28 days.

If anyone would like to see any variations on the above, please let me 
know.  I will be filling molds by 20-Mar.

Scott
