However, when polyvinyl alcohol fiber melts at around 230°C, spalling behavior of engineered cementitious composite may occur, weakening the mechanical properties and reducing ductility of high strength engineered cementitious composite. Thus, investigating the fire resistance is of great significance. By adding steel fibers to cementitious composites, qualitative and quantitative comparisons were done through observing appearance changes, spalling extent, surface cracking, mass loss, and residual mechanical properties. Results indicate that steel fiber can increase the risk of spalling and surface cracking in high strength engineered cementitious composite, improve residual mechanical abilities also. The ductility varies with steel fiber content at different elevated temperatures. Scanning electron microscopy results show that more hydration products are produced on the surface of steel fiber at 400°C, which improves interface transition zones between fiber and cementitious materials. However, an oxidation film found on the surface of steel fiber at 800°C triggers negative effect on bridging.","PeriodicalId":14868,"journal":{"name":"Journal of Advanced Concrete Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136265917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims (i) to clarify the change in resistivity in self-sensing mortar (SSM) under nondestructive compressive stress and the underlying mechanism of this change, (ii) to examine the effects of different conditions such as electric circuit and specimen dimension on this relationship. The study involved SSM specimens containing 7% carbon black powder with various parameters, including excitation voltage, intermediate resistor for the electric circuit, and electrode distance, dimensions of the cube SSM specimen. Additionally, scanning electron microscopy (SEM) observations were performed to investigate the dispersion of carbon black in the cementitious matrix. SEM observations reveal the agglomeration and dispersion of carbon black within the cementitious matrix, creating a conductive network in SSM. The measurement results showed the resistivity change was nonlinear but displayed nearly linear behavior within a specific range of compressive stress. The slope of this change increased with larger specimen cross-section, shorter electrode distance, and a smaller value for the intermediate resistor in the electric circuit. A regression analysis was conducted to predict the change in resistivity of SSM under nondestructive compressive stress, while taking these effects into account.","PeriodicalId":14868,"journal":{"name":"Journal of Advanced Concrete Technology","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135354797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
