The purpose of this study is to investigate the compressive strength properties of Ground Blast-Furnace Slag(GBFS) using water eluted from recycled coarse aggregate. When GBFS come into contact with water, they have not a autonomously chemical reaction. But GBFS is a latent hydraulic property when GBFS come into contact with water in alkaline environment. For that reason, if water eluted from recycled coarse aggregate use mixture water, GBFS is expected to reaction of latent hydraulic property in early stage. Therefore we conducted an tests of XRD, ICP-MS, compressive strength, after the mortar make form water eluted from recycled coarse aggregate. And then it is to investigate the effect of the compressive strength properties of GBFS using water eluted from recycled coarse aggregate. According to the experimentation result, ICP-MS analysis showed water eluted from recycled coarse aggregate has a high alkali-ash value of pH of 12 and over. And GBFS mortar using water eluted from recycled coarse aggregate showed a similar strength of plain mortar due to the latent hydraulic reaction. XRD analysis showed GBFS mortar using water eluted from recycled coarse aggregate have significantly decreased presence of calcium hydroxide. |
