Waste concrete has been increased by an acceleration of the development of urban and the enlargement of redevelopment projects, so recycling of waste concrete is actively progressed. However the usage is limited to a lower value-add such as the roadbed material etc. Now, the research and the development have been performed to produce the high quality recycled aggregate. However recycled fine aggregate has low quality because it contains large amount
of old mortar. Thus to produce the high quality recycled aggregate, breaking and washing process must be added to the existing process and the ingredient of old mortar must be removed from aggregate. Also, alkaline water which occur from treatment process of the waste concrete is becoming the cause of environmental problem. Accordingly, this research is to develop on the high quality recycled fine aggregate produced by low speed wet abraser using sulfur and
investigated the engineering properties of the mortar used the recycled fine aggregate by this process. Test results indicate that recycled fine aggregate by acid treatment process satisfies the quality standards of KS F 2573 (recycled fine aggregate for concrete) for the first-grade recycled fine aggregate. It is also shown that strength of mortar using recycled fine aggregate by this process was great to that using recycled fine aggregate removed under 0.15mm powder
by sieving.
