Rheological, mechanical properties, and statistical significance analysis of shotcrete with various natural fibers and mixing ratios
Autor: Kyong Ku Yun, Mohammad Shakhawat Hossain, Seungyeon Han, Choi Seunghak
Publikováno v: Case Studies in Construction Materials, Vol 16, Iss , Pp e00833- (2022)
The rheological properties of concrete with natural fibers is studied herein. Natural fibers improve the concrete performance, moreover it covers the similarity between natural fibers and cement matrix. Natural fibers may decrease the pumpability of

Microscopic investigations on the air-void characteristics of wet-mix shotcrete
Autor: Kyong-Ku Yun, Pangil Choi, Jung Heum Yeon
Publikováno v: Journal of Materials Research and Technology, Vol 8, Iss 2, Pp 1674-1683 (2019)
This paper aims to perform microscopic investigations on the air-void characteristics of wet-mix shotcrete before and after the spraying process. Both air-void analysis (AVA) and image analysis (IA) were used to monitor the air-void characteristics o

Predicting Pumpability and Shootability of Crushed Aggregate Wet-Mix Shotcrete Based on Rheological Properties
Autor: Kyong-Ku Yun, Pangil Choi, Jung Heum Yeon
Publikováno v: Advances in Materials Science and Engineering, Vol 2016 (2016)
This study aims to estimate the pumpability and shootability of wet-mix shotcrete (WMS) made with crushed aggregates and various admixtures such as silica fume, fly ash, ground granulated blast furnace slag (GGBFS), metakaolin, and steel fiber based
