2016.11.30 Typical autoclave expansion test, adopted in 1940, is currently the standard test method to evaluate the expansion effect of MgO [22]. However, limiting the MgO content alone was not enough to protect concrete from expansion. It was discovered that high contents of C 3 A and free CaO can also lead to unsoundness in cement [23].
