Hi John

Thanks for not laughing

It appears when Nasa did their testing, it was a compressive strength test.

The researchers took a "column" of the original and cooked samples and loaded then from the top in compression, the uncooked sample deformed to 1/2 the size of the cooked sample before it fractured.

So far I have found that the formations are basaltic in nature, and the reported increases in modulus ranged from minimum of 2x to 7x. Highly dependent on the sample as one would expect.

Assuming cooking works, then once the aggregate is bound in the epoxy, would we expect moisture to penetrate the epoxy?

Thanks
Al

sorry ive been gaming got a new mouse got to get used to it
ill get some data on one of our samples
we're making a 4.5 m x 1m x 1m if this deflects the figures your saying it will be scrap
think the customers gonna set the machine to 2 micron for this one as its gonna rough the item first the next 10 machines have gotta be better to finish the item
what size test pieces do u make?
