The increased freezing rate can be used to further increase the strength of aligned porous materials. The strengthened porous PVA exhibits aligned interconnected porous structures and shows a significant enhancement in tensile testing and compression strength testing.展开更多

In this paper, the reason why old bridge is damaged, the requirements for strengthening technology and construction plan for bridge strengthening are analyzed in detail, hopefully, there are some useful proposals provided for old bridge transforming.展开更多

The results showed tliat the markedly effective rates were higher in ttie two ' BiaobenJianzhi' groups than that in the two 'Zhibiao' groups.
