Porous ceramic aggregate produced from roof tile waste was used as an internal curing agent. The aim of this study is to investigate the effect of the porous ceramic aggr [...]

Properties of a molten slag and concrete containing the molten slag as a fine aggregate were investigated, which was emitted in Kure City in Hiroshima Prefecture. Water t [...]

It is a fact well known that the active additions improves the mechanical as well as de durability of concrete structures. Usually the materials are tested in laboratory [...]

The corrosion caused by the action of chloride ions represents the greatest threat to the durability and service life of reinforced concrete structures. This pathological [...]

In Japan, it is expected to use much the recycled aggregates for concrete because concrete wastes have been increasing but natural aggregate resources have been decreasin [...]

Fracture energy tests were carried out on Portland blast furnace cement-type B (BB) concrete where as an internal curing material, partial replacement of course aggregate [...]

Use of ultra high strength concrete (UHSC) is effective in improving durability of concrete structures which should lead to establishment of sustainable society. However, [...]

Electrical resistivity can be used as an indirect method to determine the chloride diffusion characteristics of in situ concrete. Chloride diffusion coefficient pertainin [...]

Though discussed a lot, the interfacial transition zone (ITZ), the linking phase between aggregate and bulk paste, still undertakes ambiguity on its knowledge. In this pa [...]

In the present study, experimental work and theoretical calculation were performed by taking into account the ITZ effect, the dilution effect and the tortuosity effect, t [...]
