Abstract:
As concrete pressure vessels are intended to have a working life of 30 years or more it is of prime importance to know the effect of operating temperatures on the properties of concrete at all ages. . .The results so far obtained indicate that, in general, a decrease in strength and modulus of elasticity occurs on the first heating and for practical purposes subsequent heating to the same temperature does not cause further losses.
