Yu-chen Qian, Li Zhang, Wei-guo Qiao, Yan-zhi Li, Yue Wu, Yun-rui Zhao
TL;DR
This study explores how temperature and material composition affect the properties of eco-friendly grouting materials used in underground engineering.
Contribution
The study systematically examines temperature and composition effects on alkali-activated grouting materials under varied conditions.
Findings
Higher temperatures accelerated strength development but reduced fluidity and increased viscosity.
Microstructural analysis showed increased precursor dissolution and polymerized aluminosilicate networks at higher temperatures.
NMR results indicated a shift to higher-coordination silicate species with increased temperature.
Abstract
Growing concerns over carbon emissions from traditional cement have intensified interest in alkali-activated materials (AAM) as sustainable alternatives. In grouting applications, key performance parameters such as strength, fluidity, viscosity, setting time, and bleeding rate are strongly influenced by both material composition and curing temperature. As underground engineering projects extend deeper, environmental temperatures gradually increase from ambient to 60 °C with depth, yet limited room-temperature studies on alkali-activated grouting materials (AAGM) cannot fully meet engineering requirements across temperature conditions. This study systematically investigated the effects of temperature (20 °C, 40 °C, 60 °C) and composition (including precursor ratios, activator modulus, and liquid-to-solid ratio) on the behavior of ternary slag-fly ash-silica fume AAGM.
