Abstract:The stress-strain relationship in compression of hydrated portland cement (with a water-cement-ratio of 0.33) and a lightweight concrete was studied at elevated temperatures. The properties of both materials seemed to be virtually unaffected by temperature UD to about 400 F. Above this, the modulus of elasticity and ultimate strength decreased with increasing temperature. These changes were more definite for hydrated portland cement.
