The Effect of Fly Ash and Recycled Aggregate on the Strength and Carbon Emission Impact of FRCCs
Source abstract
Abstract
Abstract 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 at least 90% of the performance along with a reduction of CO2 emissions from the material stage during fiber-reinforced cementitious composites (FRCCs) production by applying fly ash (FA) and recycled sand (RS). To calculate the amount of 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 emission of FRCCs were then formulated as a function of the replacement ratio of FA and RS. And binder and CO2 intensities 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, is considered most suitable in terms of performance of FRCCs and reduction of CO2 emissions.
