Effects of chloride transport properties in nano metaclayed ultra-high performance concrete towards corrosion characteristics of embedded steel / Mohd Faizal Md Jaafar
The major concern on the deterioration of reinforced concrete structure is due to the corrosion of steel reinforcement from the aggressive environment such as chloride penetration. Ultra-high performance concrete (UHPC) is an advanced concrete material having ultra-high strength with excellent durab...
