STUDY ON THE PERFORMANCE AND MECHANISM OF CEMENT-BASED SELF-LEVELING GROUT MATERIAL WITH ULTRA-HIGH EARLY STRENGTH

摘要

This paper introduces a new grout material―cement-base ultra-high early strength self-leveling grout material (GRM). It is a harmless and environmental friendly material. No affecting normal applying of construction, It can be used in the engineering required rush repairs and ultra-high early strength concrete. We mainly analyze the performance mechanism during hydrating and hardening stages and application condition of GRM in detail.
