S subjected to sulfuric acid just after the immersion periods of 7 days, 14 days, 28 days, 63 days, and 98 days. When the phenolphthalein answer was sprayed around the reduce surface of specimens, the portion of L-?Leucyl-?L-?alanine Protocol specimens in which there is residual alkalinity was revealed by a fuchsia color, as shown in Figure three. It can be observed that the neutralization depths of C-8, C-12, F-8, and F-12 specimens had been enlarged as their exposure time in acid solution elevated. On the contrary, the specimens of MK-8 and MK-12 usually do not undergo the7chroMaterials 2021, 14, x FOR PEER Overview of 17 mogenic reaction, indicating that MK specimens within this study weren’t resistant to sulfuric acid penetration.C-8 7 daysC-F-F-MK-MK-14 days28 days63 days98 Trapidil medchemexpress daysFigure three. Neutralization depths of GPC. Figure 3. Neutralization depths of GPC.The neutralization depth variation of all GPC specimens with thethe increaseexposure The neutralization depth variation of all GPC specimens with enhance of of expotime is displayed in Figure four. The specimens marked with MK-8 MK-8 and MK-12 penesure time is displayed in Figure four. The specimens marked with and MK-12 were were trated completely by sulfuric acid atacidimmersion time of 7 days. This phenomenon, however, penetrated completely by sulfuric the at the immersion time of 7 days. This phenomenon, did not appearnotthe fly ash-based GPC specimens. This indicates that indicates that mehowever, did in appear inside the fly ash-based GPC specimens. This metakaolin-based GPC has a poor resistancepoor resistance towards the acid penetration, which is consistent with takaolin-based GPC includes a for the acid penetration, that is consistent with the outcomes in Figure two. For fly ash-based GPC specimens, their neutralization depths improved using the the results in Figure 2. For fly ash-based GPC specimens, their neutralization depths ingrowth of exposure time.of exposure time. Duringof immersion, the neutralization depths creased using the growth Throughout the initial 28 days the initial 28 days of immersion, the neuof specimens prepared with low-calcium fly ash which, is marked as F, weremarked than tralization depths of specimens ready with low-calcium fly ash which, is larger as F, other folks. Following 28 days, neutralization depth from the high-calcium fly ash-based GPC specimen were higher than other individuals. Just after 28 days, neutralization depth with the high-calcium fly ash(C-8) drastically increased. Nevertheless, the specimen C-12 showed a slow development depth based GPC specimen (C-8) significantly elevated. Nonetheless, the specimen C-12 showed for the neutralization depth. The neutralization depth of C-12 specimen exposed in acid a slow growth depth for the neutralization depth. The neutralization depth of C-12 specisolution for 98 days was only 6.9 mm, which can be the minimum worth. As a result, within the light guys exposed in acid answer for 98 days was only six.9 mm, which is the minimum worth. of the final results of neutralization depth, the high-calcium fly ash-based GPC showed the best Consequently, in the light on the results of neutralization depth, the high-calcium fly ash-based GPC showed the top sulfuric acid corrosion resistance, which suggests that the improve within the Ca-content of GPC final results inside a larger susceptibility to the attack of sulfuric acid [31,32].Supplies 2021, 14,7 ofMaterials 2021, 14, x FOR PEER REVIEW8 ofsulfuric acid corrosion resistance, which suggests that the boost within the Ca-content of GPC benefits in a higher susceptibility for the attack of sulfuric acid [31,32].28C.
