In reply to Fredrik. It is much better than traditional steel. But not the best.

In reply to Spikee. After i made 3 parts(base, tower and bed) for my cnc mill in epoxi granite i will never go back to epoxy. Its hard to work with, expensive, hard to get good surface finish. Need vibro table etc, makes a mess everywhere and hard to clean. I ofcourse discovered uhpc after. But seeing how easy it is to work with, cheap, good surfacefinish, 90-150 mpa, easy to clean. its a no brainer for my next project. You can get premixed bags cheap.

45-60GPa This is the normal range, choose ordinary aggregates can be. The key is whether you do post-processing, heating, etc.
But if you want to reach more than 75GPa,All aggregates should be specially selected, and special attention should be paid to the way of post-treatment, and some pressure storage may be required for a period of time.But at present, no company can complete this value with great certainty, and it requires constant testing and adjustment, and occasionally a few can achieve it, and there is no 100% guarantee that they can achieve this strength.
