- •
Thermal strains are related to microcracking during cryogenic cooling of concretes.
- •
Strong correlation existed between thermal strain rate and AE cumulative hits rate.
- •
The average CTE of the trap rock concrete mixture was close to that of 9% Ni steel.
- •
Suitability of trap rock aggregate concrete for direct LNG containment is shown.
