  • Roller Compacted Concrete (RCC) is concrete that has no forms, no slump, no finishing, no reinforcing steel, and is wet enough to support compaction by vibratory rollers.
  • Due to the effectiveness of curing on properties and durability, the main aim of this research is to find out the effect of various curing methods (7-days water curing, air curing, permanent water curing, and emulsified asphalt curing) and ECA (lightweight aggregate).
  • With different replacement percentages of fine aggregate (volumetric replacement) on RCC and to explore the possibility of introducing practical RCC for road pavement with a minimum requirement of curing.
  • Results show that using 7% ECA improved Roller Compacted Concrete (with air curing) as compared to Roller Compacted Concrete with permanent water curing by percentages ranging from 0.5 to 1.9, 3.6 to 29.1, and 16.9 to 43.3% for bulk density, flexural strength, and water absorption, respectively.
