Effect of Admixture on Freeze-thaw Damage of Sleeve Grouting Materials by WU Zhaoyue, ZHU Haiqing

“…This paper compares the physical and mechanical properties of sleeve grouting materials with different admixtures under freeze-thaw action by means of control variable method,studies the effects of different admixtures and different contents on the apparent morphology,mass loss and strength loss of sleeve grouting materials under freeze-thaw action,and further analyzes the change of species,quantity and morphology of hydration products in freeze-thaw cycle by SEM (scanning electron microscope).The results show that:After 120 freeze-thaw cycles,the mass loss of mortar specimens with admixtures is less than 2%,which is lagged compared with the compressive strength loss;Based on the gray correlation analysis,the impact of expansion agent on the mechanical properties of mortar specimens under different freeze-thaw cycles is the lowest.However,with the addition of defoaming agent,the physical and mechanical properties of mortar specimens are more sensitive to freeze-thaw damage,and the sensitivity will increase with the increase of defoaming agent contents;From the microstructure analysis,the addition of expansion agent can improve the stability of internal C-S-H gel system after freeze-thaw action.…”

Damage evolution of Cu-inductors used for electromagnetic forming by Lisa-Marie Rymer, Lisa Winter, Maik Linnemann, Sven Winter, Verena Psyk, Thomas Lampke

“…Annealing and recrystallization processes as well as local melting at grain boundaries and formation of blowholes due to joule heating are probably the origin of the damage evolution during EMF. Understanding the correlations of these microstructural mechanisms will enable targeted heat treatment for wear-resistant inductors in the future.…”
