Method of obtaining wet-expansion deformation of hardened hydraulic concrete at non standard temperature

The invention provides a method of obtaining wet-expansion deformation of hardened hydraulic concrete at non standard temperature. The method of obtaining wet-expansion deformation of hardened hydraulic concrete at non standard temperature includes the following steps: 1) performing free volume deformation measurement before immersion of the concrete test piece in real environmental conditions, establishing a free volume deformation statistical model, separating the authigenic volume deformation component and the temperature deformation component of the concrete test piece; and 2) measuring the free volume deformation after immersion of the concrete test piece, obtaining the free volume deformation after immersion of the concrete test piece, and separating the authigenic volume deformationcomponent and the temperature deformation component from the free volume deformation after immersion, that is, obtaining wet-expansion deformation of hardened hydraulic concrete at non standard temperature. The method of obtaining wet-expansion deformation of hardened hydraulic concrete at non standard temperature can solve the problem that wet-expansion deformation of the concrete at non standard temperature cannot be measured and separated, and can obtain wet-expansion deformation of the hardened hydraulic concrete after immersion in the real environmental conditions.
