In this study, the feasibility of using steel fibers and shavings in roller-compacted concrete containing coarse basic oxygen furnace slag aggregate was investigated order to improve its mechanical properties produce an electrically conductive environment-friendly concrete. For purpose, various samples 0.4, 0.7, 1% fiber 3, 5, 7% shaving were fabricated. The compressive strength, indirect tensi...

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 ...

There is no doubt that concrete one of the most consumed materials all over world. It a composite mix widely used for constructing structures and infrastructures to sustain environmentally induced stresses such as thermal seismic. As mainstream construction industry tended find out feasible solutions, Roller Compacted Concrete (RCC) was introduced play an essential role in development dams pave...

Reducing start and stop time without destroying the pavement surface is important in enhancing productivity of double-drum roller and compact quality of asphalt pavement, but it is difficult in confirming the maximum brake deceleration or start acceleration of double-drum roller. Dynamic analysis is used in studying these questions, and a mathematic model of double-drum roller is established, b...
