Question

What is the bending strength of this concrete?

(a) 60-115 MPa

(b) 10-16 MPa

(c) 35-50 GPa

(d) 500 GPa

This question was posed to me in a job interview.

My doubt is from Sulphur Infiltrated Concrete, FRC topic in division Special Concrete and Concreting Methods of Concrete Technology

Answer 1

Right option is (b) 10-16 MPa

To explain I would say: 10-16 MPa is the bending strength of the Sulphur Infiltered concrete where as OPC has 6-7 MPa.
