A Modulus Variation Model of Concrete under External Sulfate Attack:New Perspective from Statistical Evolution of Microcracks
《Journal of Wuhan University of Technology(Materials Science)》2018年第6期1465-1471,共7页ZHANG Hao SHE Wei 
Funded by the National Key R&D Program of China(No.2017YFB0309904);the 973 Program of China(No.2015CB655100)
A numerical model was proposed to describe the modulus variation of mortar exposed to external sulfate attack and the effectivity was verified by experiments. The model joints statistical evolution of microcracks to e...

Effect of Al in Slag Blended Cement Paste under Sulfate Attack被引量：1
《Journal of Wuhan University of Technology(Materials Science)》2017年第5期1087-1094,共8页胡玲玲 何真 TANG Shengwen LI Yang 
Funded by the National Key Research Program(973 Program)(No.2015CB655101);National Natural Science Foundation of China(No.51379163)
Unilateral sulfate attack of cementitious materials containing 40% slag with different water to binder ratios was investigated. The results showed that the degradation of slag blended cement pastes was nearly from the...
