Nano silica sol (NSS) grouting is an effective method to improve water blocking capacity of rock fracture and fine sand. However, the mechanical and rheological properties of NSS grout remain poorly investigated. We study the properties by (1) measuring gelling time of NSS grout with a different acc...
