*2.3. Concrete Mix Proportions*

The artificial aggregate types were produced to develop the concrete mixes in the experimental investigation. FA and GGBFS were combined with crushed QP powder in the LWA production process. The materials used to make the artificial aggregate and the replacement ratio with coarse aggregate are listed in Table 2. A complete list of the concrete mix proportions used in the investigation is provided in Table 3. FAAC, GGBFSAC, and QPAC refer to the FA, GGBFS, and QP aggregate concrete mixtures in Table 3. This also shows how much superplasticizer (SP) was needed to achieve appropriate workability.
