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 [...]

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

Lime–based mortars of adequate workability are used for repairing coating mortars on old masonry in historical buildings. The analysis of a great number of old plasters [...]

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 [...]

This study investigated the influence of the molten slag as fine aggregates of concrete on the structural performance of RC beams. In the loading test, the mechanical res [...]

In order to promote the use of recycled aggregate and take measure to the heat island effect, porous pervious concrete is the useful materials. We evaluated the cooling e [...]

Self compacting concrete (SCC) is a very fluid concrete that is characterized by its high volume of paste, and the use of superplasticizer. The effects of recycled aggreg [...]

For high durability and strength, decreasing of the water to binder ratio of cement is needed by using of fly ash, blast furnace slag as mineral admixture. And it is poin [...]

In this study, advanced greyscale imaging analysis was conducted using the Adobe Photoshop 6 on the surfaces of masonry stones, taken from listed historic buildings, to a [...]

Cold recycling techniques continue to become standard technology used for Czech roads rehabilitation, which has been presented during the last years in several papers inc [...]

An experimental program has been carried out on recycled concrete with the aim of establishing the relation between the static modulus of elasticity Es and the dynamic on [...]

Argentina has an heritage of masonry construction of walls and floors of both collective and individual homes. These pieces, called bricks, ceramic blocks, ceramic mezzan [...]

In this study, optimum combinations of the replacement ratios of fly ash (FA) and ground granulated blast-furnace slag (BS) with cement were examined from the aspect of p [...]

Current loads from cement production make material responsible for 5-7% of CO2 emissions with more than 2x109 ton of CO2 emitted. Considering available industrial product [...]

A new technology is presented for transforming returned concrete into a granular material that can be reused as aggregates for concrete. The new method is based on non-to [...]

Waste concrete accounts for a substantial fraction of construction waste, and the recycling of waste concrete as concrete aggregate for construction is an important chall [...]

For high fluidity concrete beams with medium-quality recycled coarse aggregate and melt-solidified slag aggregate, we investigated the fresh concrete properties and the b [...]

This study evaluates the size effect in the shear performance of reinforce concrete beams with recycled coarse aggregates. The test variables include the type of aggregat [...]

High quality recycling aggregate nearly same with virgin aggregate has been passionately developing in the recent years due to the establishment of the low emission socie [...]

The shear-friction behavior of the recycled aggregate concrete (RAC) compared to the natural aggregate concrete (NAC) is investigated. Two out of six concrete specimens w [...]

The construction sector is among the most resource- and energy-consuming industrial activities. Particularly, according to recent surveys, the emissions of greenhouse gas [...]

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 [...]

An entire concrete waste reuse model for producing recycled aggregate class H concrete was established with the objective of recycling concrete waste generated during ant [...]

Compared with the study on high-quality of recycled coarse aggregate, the study on recycling of recycled fine aggregate still has been limited. This study has quantitativ [...]

Application of the recycled aggregate is a promising technology for resource saving and low environmental impacts, which is more effectively performed when recycled fine [...]
