In order to facilitate the use of recycled aggregate, Hong Kong has recently published specifications for using recycled aggregate in concrete. However, Hong Kong only allows using recycled aggregate as a 100 % replacement and a 20 % replacement of natural coarse aggregate (WTBC 2002). In the coarse and fine aggregates must satisfy the grading limits as shown in Table 10.
