To develop a design method for concrete using low-quality recycled aggregates, an experimental study was conducted on applicability to examine the structural strength correction value (S value) and calculation of mix proportion strength of recycled aggregate concrete-Class M, which used recycled aggregate class L mixing with the normal aggregate. Cement used in the experiment was ordinary Portland cement (in this case, fly ash type II was used as a fine aggregate substitute), Portland blast-furnace slag cement type B, and low-heat Portland cement. As a result, the mix proportion strength of recycled aggregate concrete-Class M could be determined using the S value according to JASS 5 (2018) as normal-weight concrete. Full article
