There is common confusion about the terms “High strength concrete” and “High performance concrete” and it appears that they refer to the same thing. In fact, “High performance concrete” refers to the concrete which has been specially designed to achieve a certain particular characteristics such as high abrasion assistance and compaction without segregation.
It may turn out that the designed concrete would possess a high strength but this is obviously not the original intention.
“High strength concrete” is designed to have concrete strength of 70MPa and more.
