Geopolymers can replace cement and help reduce the environmental impact of concrete construction, but research is needed to ensure their mechanical properties, durability practicability. The aim this investigation examine influence ground granulated blast furnace slag (slag) content on performance, at fresh hardened states, fly ash (FA) based self-compacted geopolymer (SCGC). For purpose, four ...

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 ...

Abstract Compaction is a fundamental step in pervious concrete production and affects its mechanical hydraulic properties. In this study, two mixtures were compacted with three different energies, distributed layers. The effects on porosity, strength conductivity evaluated. increase compaction energy resulted proportional reduction porosity. Increases compressive from 17 to 36% observed. Howeve...
