GFRP reinforced concrete : environmental and movement characteristics
… the problem of corrosion in steel reinforced concrete. Consequently, methods such as cathodic protection, epoxy coatings, concrete additives, etc., have been tried. Unfortunately, non of these methods has totally solved the corrosion problem. The outstanding characteristics of fibre reinforced …

Modeling recycled aggregate concrete crack by extended finite element method and concrete damage plasiticity
Crushing concrete to bring the aggregates back to be used for concrete structures is a process of creating recycled aggregate (RA). Recycled aggregate concrete (RAC) has become increasingly important in the field of construction. The use of recycled aggregate concrete made from recycled aggregate …

Drinking Water Treatment Waste as an Alternative for Internal Curing and Cement Replacement in Concrete
Concrete can be a highly durable construction material when permeability is low. Hydrating cement paste shrinks through several mechanisms broadly grouped into autogenous and drying shrinkage. These mechanisms cause cracks which become high permeability routes for water and aggressive ion movement, …

The influence of high performance matrices on fracture behavior of concrete
… and fly ash is known to improve the strength of concrete, but its contributions to fracture behavior remains unclear. In this study, the influence of replacing cement by silica fume and fly ash on the cement matrix-coarse aggregate interfacial bond, compressive stress-strain behavior and fracture …

The Hydrogeologic effects of fly ash utilization in concrete at Coal Creek Station, Underwood, North Dakota
… the installation of 5,288 cu yds (4,043 m3) of concrete in roadways at ccs. The concrete contains a 70% replacement of Portland cement with fly ash. The purpose of this study was to determine whether or not use of fly ash in concrete releases any environmentally deleterious substances to soil or …
