By means of compressive and flexural bond strengths, fiber pullout, mercury intrusion porosimeter (MIP) and backscattered electron imaging (BSE) analysis, an enhanced insight was gained into the evolution of FR-MPC performance before and after vibration. Experimental results showed that the compressive strength and flexural strength of FR-MPC was increased when it was subjected to vibration. However, the effects of vibration on the flexural strength of plain magnesium phosphate cement (MPC) mortars was insignificant. The increased flexural strength of FR-MPC after vibration could be due to the high average bond strength and pull-out energy between the micro-steel fiber and the MPC matrix. Moreover, BSE analysis revealed that the interface structure between FR-MPC and an ordinary Portland cement (OPC) substrate was more compacted after vibration, which could possibly be responsible for the better bonding properties of FR-MPC. These findings are beneficial for construction project applications of FR-MPC in bridge repairing and widening.<\/jats:p>","DOI":"10.3390\/ma14247743","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T09:02:19Z","timestamp":1639558939000},"page":"7743","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Effect of Vehicle\u2013Bridge Coupled Vibration on the Performance of Magnesium Phosphate Cement Repair Materials"],"prefix":"10.3390","volume":"14","author":[{"given":"Sijia","family":"Liu","sequence":"first","affiliation":[{"name":"Key Laboratory of Advanced Civil Engineering Materials of Ministry of Education, Tongji University, Shanghai 201804, China"},{"name":"School of Materials Science and Engineering, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5796-6426","authenticated-orcid":false,"given":"Long","family":"Yu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Civil Engineering Materials of Ministry of Education, Tongji University, Shanghai 201804, China"},{"name":"School of Materials Science and Engineering, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Han","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Civil Engineering Materials of Ministry of Education, Tongji University, Shanghai 201804, China"},{"name":"School of Materials Science and Engineering, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Pan","sequence":"additional","affiliation":[{"name":"Shanghai Construction No. 5 (Group) Co., Ltd., Shanghai 200063, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kai","family":"Wu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Civil Engineering Materials of Ministry of Education, Tongji University, Shanghai 201804, China"},{"name":"School of Materials Science and Engineering, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenghong","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Civil Engineering Materials of Ministry of Education, Tongji University, Shanghai 201804, China"},{"name":"School of Materials Science and Engineering, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"123274","DOI":"10.1016\/j.conbuildmat.2021.123274","article-title":"The improvement of freezing\u2013thawing resistance of concrete by cellulose\/polyvinyl alcohol hydrogel","volume":"291","author":"Wu","year":"2021","journal-title":"Constr.
