Description
Guangtao Yu and five co-authors developed a new grouting material for cracked rock slopes in a 2024 paper. Grout is pumped into cracks to hold a slope together, but standard cement grout costs a lot, uses much energy, and can crack away from the rock. The team built a greener mix from two waste products, gypsum from flue gas cleaning and slag from iron furnaces.
Lab tests varied the mix ratios and an additive to find the best blend for setting time, flow, shrinkage, and strength. One ratio stood out as the best balance. The team then compared the new material with cement grout in strength tests and in computer models of cracked slopes. The waste-based grout held the cracked rock well and bonded tightly to it. The work offers a cheaper, cleaner option for keeping weak mudstone slopes stable.
