Hi Thomas - One of their mixes claims E=80GPa. Give that a go. I expect in flexure it will be lower than the compression value. That would be interesting. I tried to get some shipped here some years ago but they would not sell it outside EU. Some of the gouts and cretes I see here now have the compression modulus and the acoustic or "dynamic" modulus quoted. The acoustic modulus is usually close to the compression modulus. Unfortunately, the acoustic is a compression process so they are similar. Need a pure tension test to really see the delta. Peter

larger aggregate is cheaper less processing and fills large gaps.

Yeah, i'll see if i can order the stuff for a test af that...it will take a couple of weeks since i have a lot of traveling in the upcoming weeks...

Maybe i should figure out a (simple) way to measure dampningen aswell...as i feel that it would be the major tradeoff one is "sacrificing" for better modulus... otherwise i would just grap af piece of steel with 10x modulus of EG and say that "steel is much better"...i just haven't found a good way to test this "at home"....it would also be interesting to compare this between EG and grout...
