ABSTRACT In this empirical investigation, the effect of four concrete mixtures was examined, namely, control concrete (CC), binary blended metakaolin concrete (BBMC), binary blended pond ash concrete (BBPC), and ternary blended metakaolin and pond ash concrete (TBMPC). In this study, a total of 288 specimens were manufactured, including CC, BBMC, BBPC, and TBMPC, which were subjected to curing for 28 and 90 days. The mix compositions used were in a ratio of 1:1.75:2.22, with a water-binder ratio of 0.44. The study delved into an extensive examination of both the fresh and mechanical properties of these concrete mixtures. Additionally, the sustainability analysis for all mix proportions were computed. The results demonstrate significant enhancements in compressive strength (fcs), split tensile strength (fsts) and flexural strength (ffs) with an increase of 17.82% and 19.81%, 12.32% and 13.50%, 13.34% and 14.39%. These improvements were observed specifically in the M6P6 mix, composed of 88% PC, 6% MK, and 6% PA. In the context of sustainability analysis, the PA20 mix displayed the lowest carbon footprint emissions, measured at 351 kgCO2/m3. On the other hand, the MK6PA6 mix demonstrated the highest CO2 intensity, with values of 0.095 MPa/kgCO2·m3 and 0.114 MPa/kgCO2·m3. investigation examined namely CC , (CC) BBMC (BBMC) BBPC (BBPC) TBMPC.

ABSTRACT Concrete technology has seen a recent advancement with the widespread adoption of Engineered Cementitious Composite (ECC). Typically, ECC consist of cement, fly ash, fine sand, fibers, and occasionally other additives or mineral admixtures. However, there has been no exploration into the effects of combining pond ash with steel fibers on emerging cementitious materials like ECC. In this study, seven ECC specimens were made. One was a control mix, and the other six included pond ash with increments of 10% from 10% to 60%. All seven mixes were maintained at a fixed ratio of fly ash 40% and water-to-binder ratio of 0.3. To boost the fresh mix of the ECC mixes, superplasticizer was introduced at a rate of 1% by volume, and steel fiber was incorporated at a rate of 2% by volume of ECC. Addition of pond ash into ECC results exhibits superior properties than control mix. .
