| Abstract |
The natural aggregate will be dried up within 30 years due to the great amount of consumption in making of construction materials. For conserving natural aggregate resources, the waste concrete can be recycled as a important construction materials. Until now, the recycling aggregate manufactured from the waste concrete has been taken a side view of concrete. For the promotion of consumption of recycled aggregate, it is very important to make a study of manufacturing construction waste into good quality recycled aggregate and developing practical use for it.
In this study, we investigated the evaluation for properties of recycled fine aggregate, produced by wet process, according to the rate of the construction waste, and the effect on basic properties of dry premixed mortar, manufactured in bulk for architectural use, used recycled fine aggregate.
We could find that the properties of recycled fine aggregate have been significantly improved by increasing the ratio of waste concrete as raw material, and the properties of dry premixed mortar is not much influenced by the existence of recycled fine aggregate, because particle size distribution is well classified through manufacturing process it. As a result, it is considered that the application of recycled fine aggregate in dry mortar system is sufficient. |
