Figure 1
(a) Box plots of the means ± standard deviations of the surface microhardness of pilot study on white ordinary Portland cement. (b) Box plot of the means ± standard deviations of the surface microhardness (overall) before exposure to 37% hydrochloric acid and phosphate buffer saline. (c) Box plot of the means ± standard deviations of the surface microhardness (overall) after exposure to 37% hydrochloric acid and phosphate buffer saline. (d) Box plot of the means ± standard deviations of the push-out bond strength before exposure to 37% hydrochloric acid and phosphate buffer saline. (e) Box plot of the means ± standard deviations of the push-out bond strength after exposure of 37% hydrochloric acid and phosphate buffer saline which illustrate the means ± standard deviations.
