요약2 Concrete is the most widely used construction material in the world. In particular, cementitious composites that contain reinforced fibers have a relatively large amount of cement. Therefore, in this study, the target is to maintain atleast 90% of the performance along with a reduction of CO2 emissions from the material stage during fiber?reinforcedcementitious composites (FRCCs) production by applying fly ash (FA) and recycled sand (RS). To calculate the amountof CO2 emission at the stage of manufacturing the FRCCs, life cycle inventory database (LCI DB) were referenced from domestic and Japan. As the performance efficiency indicators, simple equations to evaluate the amount of CO2 emis? sion of FRCCs were then formulated as a function of the replacement ratio of FA and RS. And binder and CO2 intensi? ties were analyzed by FRCCs strength. Based on the results for the test, a mix of FA 25% and RS 25% of W/B 0.45, isconsidered most suitable in terms of performance of FRCCs and reduction of CO2 emissions.
