Question

What is the compressive strength for UHPC?

(a) 10-20 MPa

(b) 60-100 MPa

(c) 100-150 MPa

(d) >150 MPa

I had been asked this question by my school teacher while I was bunking the class.

My question is taken from Ultra High Strength Concrete in chapter Strength of Concrete of Concrete Technology

Answer 1

Correct choice is (c) 100-150 MPa

For explanation: 28 days compressive strength for UHPC is 100-150MPa and for HPC, it’s 60-100 MPa.
