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.
A day without math is like a day without sunshine.
