This review shows that global sugarcane production reached 0.012 billion metric tons of bagasse ash (BA) in 2018, with Brazil, India, and China as top three producers. industrial BA has a high loss on ignition (LOI). Hence, further burning at 800 °C for 1 h or lower temperature 600–650 longer duration up to 3 is the most optimum producing amorphous silica. The average chemical composition used reviewed paper 65% silicon dioxide (SiO2), 9.21% aluminium oxide (Al2O3), 4.64% iron (III) (Fe2O3), 8.31% LOI. exhibits pozzolanic activity can be supplementary cementitious material (SCM). Using 10% dosage replacing ordinary Portland cement (OPC) (by mass) increased long-term (28 days afterward) compressive, flexural, tensile strengths. However, higher dosages 30% produced strength but more than 75% OPC control mortar. requires water superplasticizer (SP) attain similar workability mix due fibrous flakey particles. Most researchers found absorption permeability decrease increases by mass. Concrete containing 20% enhanced durability against sulfate & sulfuric acid attacks, chloride ion ingress, alkali-silica reaction (ASR). recommends sugar industry optimize process produce, conjunction construction industry, standard guideline conformity enhance its use SCM. Also, research should conducted utilizing filler SCM two-stage concrete (TSC), ultra-high-performance (UHPC), self-compacting (SCC).

In previous literature, multi-criteria decision-making (MCDM) methods and life cycle assessment (LCA) methods, integrating different properties, have been applied to cementitious materials separately. This study addresses the existing gap in research by comparing LCA with durability parameters integrated MCDM concrete mixtures. The aim is assess differences between these two approaches when assessing overall sustainability of materials. Concrete mixtures containing conventional recycled materials, such as supplementary (SCMs) aggregate (RCA), are evaluated based on their mechanical parameters, environmental impact, cost. results highlight positive impact SCM usage performance emphasizes importance reducing cement content for sustainability. Careful RCA utilization crucial due variable outcomes combined SCMs. also exhibit that various show acceptable ranking mixtures, offering flexibility property weighting applications. contrast, yield higher differences, emphasizing superior consistency methods. sensitivity analysis highlights significance weight parameters. Standardizing procedures specific applications recommended ensure reliability relevance results.

Three different eco-friendly clinkers were produced, investigated, compared with one that is commercially available. BB was used to replace 49.2%, 77%, 80.3% limestone by total amount clinker. Two selected produce cement pastes, their impact on compressive strength at 28 days examined. The results suggest substituting does not adversely affect paste. Moreover, employing 77% or production significantly influence alite belite contents but slightly increases tricalcium aluminate ferrite phases while reducing periclase content.
