Aug 23 2019The process of curing concrete becomes more challenging in cold weather since to properly set and reach maximum strength fresh concrete must be protected from freezing for at least the first 24 hours or until it reaches a minimum strength of 500 pounds per square inch (psi) Concrete that freezes at an early age can lose much of its overall strength 1 INTRODUCTION In concrete technology there is a highly remarkable type of concrete named Ultra-High-Performance Concrete (UHPC) Just like Normal Strength Concrete (NSC) UHPC is composed of the same standard materials like cement aggregate mineral admixture chemical admixture and water
