For majority of aggregates, the coefficient of thermal expansion lies between approximately ____________
(a) 5.4 * 10^-6 and 12.6 * 10^-6 per ^oC
(b) 10.8 * 10^-6 and 16.2 * 10^-6 per ^oC
(c) 5.4 * 10^-6 and 10.8 * 10^-6 per ^oC
(d) 10.8 * 10^-6 and 12.6 * 10^-6 per ^oC
I got this question in semester exam.
My doubt stems from Thermal Properties in section Aggregates and Testing of Aggregates of Concrete Technology
