Question

Range of modulus of elasticity for UHPC ___________

(a) 30-35 GPa

(b) 35-40 GPa

(c) 40-45 GPa

(d) 45-50 GPa

I had been asked this question in a national level competition.

I would like to ask this question from Ultra High Strength Concrete in division Strength of Concrete of Concrete Technology

Answer 1

Correct choice is (d) 45-50 GPa

To elaborate: 45-50 GPa or 6500 to 7300 ksi is the range of modulus of elasticity for ultra-high performance concrete.
