...Mohd Firoj; Ashish Bahuguna Concrete structures deteriorate due to water ingress and aggressive chemical penetration, leading to steel corrosion, spalling and reduced durability. To mitigate these issues, the use of a crystalline admixture ( CA ) in concrete was explored in this study. The CA...

... molar to 16 molar resulted in a continuous decrease in the workability of GPC. The target slump of more than 150 mm was achieved even for high sodium hydroxide concentration due to the presence of high-range water-reducing admixture. However, the increase in sodium hydroxide concentration positively...
