| Abstract |
This study was executed to improve the low quality of recycled aggregate by reducing absorption ratio, filling internal/external voids, and improving adhesion of mortar. Recycled aggregate was precoated using penetrating surface hardener - solution of silicate composite. Concrete was manufactured mixing precoated and non-precoated recycled aggregate.
The result represents that the absorption ratio of recycled aggregate was degraded 40% lower than that of precoating treatment and precoated recycled aggregate concrete was higher than non-precoated recycled aggregate concrete in compressive strength, bending strength. Moreover, precoated recycled aggregate concrete was upgraded about 9～27% upper than non-precoated concrete in case of mechanical properties. It is caused by adhesion to be developed by precoating treatment. |
