I need to know the maximum compressive strength achieved so far with concrete. What name is given to this concrete ?
Richard P,and cheyrey (1995) achieved the maximum compressive strength 810 mpa in reactive powder concrete,they will made evolution on concrete.

As far as I know some 700 MPa had been reached already. However, usual mixtures develop a strength of around 200 MPa.
A state-of-the art on UHPC is reported in this paper published on 2008.

If you mean the highest compressive strength of concrete actually used in construction, the answer seems to be concrete with design compressive dstrength of 300 N/mm2 , which has been developed and used by Taisei Corporation in Japan. I believe that the concrete was for columns that were pre-fabricated and that steam curing is necessary for achieving that level of strength. There is a brief mention about the building where the 300 N/mm2 concrete was used in the following URL:

Taiheiyou Cement Corporation of Japan has recently developed a new cementitious material that is claimed to deliver record compressive strength of 464 N/mm2 using normal pour-and-form techniques.
(See http://www.taiheiyo-cement.co.jp/english/summary/pdf/150605.pdf).
However, actual use in construction has not been reported yet and is probably many years away.
There have been reports elsewhere that compressive strength of 673 N/mm2 using reactive powder concrete (RPC) technology has been achieved. However, this requires curing of concrete under high temperature and pressure (hot-press forming at 250°C to 400°C.)
