Figure 3.
(a, b) Mass, (c, d) volume changes of the materials after 1 week in different soaking solutions showing (a) the variation of the data obtained by the different operators for the changes in mass and (b) pooled data; (c) there was less inter-operator variation for the volume determinations and (d) indicating the higher volume changes for tricalcium silicate compared to the other materials. All testing independent of the solution used.
