Factors affecting the expansion ratio and flow consistency of expandable foam grout for subsurface improvement
Autor: WooJin Han, Jong-Sub Lee, Dongsoo Lee, Jongchan Kim
Publikováno v: Case Studies in Construction Materials, Vol 21, Iss , Pp e03544- (2024)
Highly porous cementitious materials have been utilized in various geotechnical applications, such as filling subsurface cavities, backfilling, and enhancing loose layers. In particular, expandable foam grout (EFG) has significant potential for cavit

Prediction of flowability and strength in controlled low-strength material through regression and oversampling algorithm with deep neural network
Autor: WooJin Han, Dongsoo Lee, Jong-Sub Lee, Dae Sung Lim, Hyung-Koo Yoon
Publikováno v: Case Studies in Construction Materials, Vol 20, Iss , Pp e03192- (2024)
In urban areas, backfilling voids with complex and narrow shapes necessitates alternative backfill methods and materials, such as controlled low-strength materials (CLSMs), to minimize ground subsidence caused by improper compaction of backfill soils

Pore topology, volume expansion and pressure development in chemically-induced foam cements
Autor: WooJin Han, Junghee Park, Wonjun Cha, Jong-Sub Lee, J. Carlos Santamarina
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-10 (2022)
Abstract Foam cement is an engineered lightweight material relevant to a broad range of engineering applications. This study explores the effects of aluminum chips on cement-bentonite slurry expansion, pressure development, and the evolution of pore
