“…[32,34,36,37]. Exploration of particle packing revealed that particle packing follows various models, with the trademark measurement being above or below 0.23 proportions, so 0.23 was considered to be the normal state of packing design [32,37]. In the present study, 20 mm was NMAS, 10 mm was HS, 4.75 mm was PCS, 1.18 mm was SCS, and 0.3 mm was TCS.…”

“…17a and 18k) revealed calcium-depleted paste with a new class of microcracks, which appeared due to the heat of hydration [86]. This is due to un-hydrated calcium hydroxide platelets in the concrete matrix, as well as small CSH fibres that cover the anhydrous calcium silicate grains of calcium silicate [37,87]. It demands supplementary pozzolanic materials to compensate for microcracks, and at present, the addition of FFA as a partial replacement to OPC fulfils the demand.…”

“…However, this technique was found to be most suitable for self-compacting concrete (SCC) where it was purely based on the particle orientation factor, which was necessary where it would be expected that aggregate must self-orient itself to achieve the densified compacted state [35,36]. Further BAGT was found to be more suitable for recycled-based SCC [37]. However, to date, no study has been performed by utilizing BAGT with TRCA in SCC, and it was found to be a research scope of interest.…”

The present study concentrates on the performance evaluation of calcined and uncalcined cashew nut-shell ash (UCCNA and CCNA) with treated total recycled concrete aggregate (TRCA) in self-compacting concrete. The achievement of sustainable self-compacting concrete (SCC) is possible by the implication of four stages, which includes TRCA treatment process, gradation selection process through Bailey aggregate grading technique, by considering TRCA replacement percentage with an increment of 25% and up to 100% and by considering UCCNA or CCNA replacement with an increment of 5% and up to 20%. Hardened and fresh properties of SCC have been performed and analyzed based on the compliance requirements of SCC. In addition finding results through microstructure assessment was in line with the findings of the hardened and fresh properties of SCC. In addition, quality and dynamic instability assessments of SCC were analyzed through ultrasonic pulse velocity and drying shrinkage aspects. Besides CO2, the emission rate and the efficiency rate of SCC, composites were analyzed in detail. Overall findings revealed that CCNA-based SCC mixes performed effectively than UCCNA-based SCC; specifically, incorporation of 75% of TRCA with 15% CCNA was found to be optimal. But with regard to shrinkage performance UCCNA found to be better by imputing less shrinkage compared to CCNA-based SCC mixes. Further with regard to efficiency rate of SCC composites revealed the gain of maximum efficiency of about 0.156 MPa/kg CO2/m3 and 0.160 MPa/kg CO2/m3 for 15% and 20% CCNA-based SCC mixes.
