Question

What is the linear coefficient of thermal expansibility for this concrete in 10^-6/K?

(a) 8-12

(b) 8-10

(c) 10-15

(d) 12-15

The question was asked in my homework.

I'm obligated to ask this question of Sulphur Infiltrated Concrete, FRC topic in division Special Concrete and Concreting Methods of Concrete Technology

Answer 1

Correct answer is (a) 8-12

To explain: 8*10^-6/K to 12*10^-6/K is the linear coefficient of thermal expansibility for sulphur infiltered concrete where as 8*10^-6/K to 10*10^-6/K is for OPC.
