研究室紹介
Professor Juhyuk Moon's research lab specializes in advanced cementitious materials and sustainable construction technologies, focusing on the development of high-performance, low-carbon cements and concretes. Key research directions include the fundamental understanding of cement hydration mechanisms through thermodynamic and quantum chemical modeling, the engineering of novel cementitious systems such as limestone-modified cements and ultra-high-performance concrete (UHPC), and the integration of advanced materials like carbon nanotubes and hollow microspheres for multifunctional and lightweight structural composites. The lab also leverages machine learning and advanced imaging techniques to optimize material dispersion and performance at the microscale.

15ABSTRACT This study investigates the feasibility of using ground coal bottom ash (CBA) as a partial replacement for Portland cement (PC) in ultra‐high‐performance concrete (UHPC). PC was replaced with CBA at levels of 10, 20, 30, and 50 wt.%, and the resulting effects on hydration behavior and mechanical properties were systematically evaluated. A 10 wt.% replacement of PC with CBA resulted in improved compressive strength, whereas higher replacement levels led to strength reduction mostly due t
Ultra-high-performance concrete (UHPC) has gained increasing attention for its superior mechanical and durability properties. Recent efforts have focused on advancing next-generation UHPC technologies that align with CO2 reduction and performance enhancement goals. This study presents a focused summary of four emerging research directions: (1) clinker-free UHPC through enhanced pozzolanic reactions, (2) in-situ CO2 premixing and curing for carbon fixation, (3) lightweight UHPC incorporating holl
A portion of chloride salt is usually introduced to improve the early strength of slag cement, but it increases the possibility of chloride corrosion. This study investigates the effect of diethanol-isopropanolamine (DEIPA) on the chloride distribution and mechanical strength in a high-volume slag cement (HVSC) system containing 60 wt% slag and 1.11 wt% NaCl. In the absence of NaCl, DEIPA enhanced the aluminate reaction of HVSC, producing more hemicarbonate. As a result, DEIPA addition increased
ABSTRACT In this study, the grinding impact of monoethylene glycol (MEG) in varying amounts (0%, 0.02%, and 0.1%) on ground‐granulated blast furnace slag (GGBFS) was assessed. The mechanical and hydration properties of ordinary Portland cement (OPC) blended with 50 wt.% of GGBFS were also investigated. The inclusion of MEG enhanced the grinding performance of the GGBFS, with a more pronounced effect at higher MEG concentrations. Moreover, MEG somehow altered the hydration reactions of OPC and GG
Carbon nanotube (CNT)/cement composite is a promising material for structural health monitoring, where CNT dispersion and content critically affect the conductive network for self-sensing. Still, a simple method to assess low CNT levels is lacking, limiting their large-scale production. This study applied machine learning (ML) and convolutional neural networks (CNN) to predict these factors from optical microscopic images. A custom 2D-CNN directly learned spatial features from cropped images, re
