The quantitative functional relationship between restrained expansionstrain and percentage of rein forecement is studied as well.

Hot strain of concrete includes constrained strain of causing stress and free expansionstrain, and then the unconstrained concrete device is designed just for distinguishing them.
Moreover, the boundary constraint has significant impact on the general swelling force, and slight increase of expansionstrain will cause dramatic decrease of the general swelling force.
