Assessing the Effect of Using Porcelanite on Compressive Strength of Roller Compacted Concrete
نویسندگان
چکیده
Roller-Compacted Concrete (RCC) is a zero-slump concrete, with no forms, reinforcing steel, finishing and wet enough to support compaction by vibratory rollers. Because the effectiveness of curing on properties durability, primary scope this research study effect various methods (air curing, emulsified asphalt(flan coat) 7 days water permanent curing) different porcelanite (local material used as an Internal Curing agent) replacement percentages (volumetric replacement) fine aggregate some RCC explore possibility introducing more practical for road pavement minimum requirement curing. Cubes specimens were sawed from slabs (38*38*10) cm determination compressive strength. The results show that using (5) % improved strength (with air compared reference percentage ranging from(-2.9 6)%.

Investigating the Effect of natural Pozzolans on Mechanical Properties of Roller Compacted Concrete
Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...
