Web2.2.4 Freeze–Thaw. The freeze–thaw process represents a “mild” homogenization procedure and it is usually used in combination with other homogenization methods. It consists of quickly freezing at −85°C and thawing at 4°C in sequence (the tubes could be thawed quickly at 6–10°C in a water bath for 10 min and kept at 4°C). WebNov 1, 2024 · Freezing and thawing resistance is a key characteristic for concrete materials in cold weather conditions. In this study, the tensile properties and elastic modulus of ultra-high performance concrete (UHPC) under accelerated freeze-thaw cycles are characterized. Six series of UHPC specimens are experimentally tested with a well … if and dates
