Using biomass ash to partially replace cement reduces the cement industry’s environmental impact and prevents these agro-industrial wastes from ending up in landfills, eroding soils, or being openly burned. This research aims to select three biomasses to produce supplementary cementitious materials (SCM) through the analytic hierarchy process, considering expert judgments from different domains. Complementary to up-to-date research, we evaluated biomasses taking into account biomass production, ash obtained from combustion, and logistics processes for supplying concrete plants with SCM. We also dealt with an industrial context instead of a laboratory one and validated our approach on a real case study using Colombian data. The results indicate experts count the technical viability of biomass (concrete properties) as the most crucial criteria, followed by the availability and transport characteristics of the waste (production criteria) and the combustion process as the least important criteria. In the baseline scenario (all experts’ judgments having the same weights), we found that cane bagasse is the best alternative, thanks to its large and highly concentrated production, even if it is not the biomass with the best pozzolanic properties. We also analyzed other scenarios in which we changed the weights of the experts’ judgments and the importance of the criteria. We found that cane bagasse, rice husk, and palm rachis remain the three biomasses selected as SCM, showing the robustness of the proposed multicriteria decision-making (MCDM) methodology. The results provide a methodological reference to appraise biomasses for SCM nationally, using a MCDM framework in a group decision-making context.

“…There also very few papers dealing with issues identical to those analysed. Praveenkumar et al [ 48 ] and Pinto et al [ 49 ] applied the AHP method in the first case to evaluate the performance of HPC, in the second case to select the best mix type for the production of HPC. The paper [ 50 ] compares the application of OPC (Ordinary Portland Cement) and ultra-high-performance concrete, taking into account the environmental effects, using the SD (System Dynamics) method to analyse the development of the construction sector.…”

Optimal Selection of High-Performance Concrete for Post-Tensioned Girder Bridge Using Advanced Hybrid MCDA Method

et al. 2021

The selection of material solutions is a basic decision-making problem that occurs in engineering issues. It affects the entire life cycle of a building structure, its safe use, maintenance costs, and a need to meet requirements for sustainable development, including recycling. This paper aims at selection of the optimum composition of HPC designed for monolithic girder structures of post-tension bridges. For the analysis, a set of 12 new-generation concretes (HPC) was designed, made, and tested. A full-scope set of evaluation criteria was created and then the optimal alternative was selected. For this purpose, an advanced hybrid algorithm combining EA FAHP (Extent Analysis Fuzzy Analytic Hierarchy Process) and FuzzyTOPSIS (Fuzzy Technique for Order Preference by Similarity to an Ideal Solution) methods was used. The obtained results indicate a possibility for the practical application of the proposed algorithm by decision-making engineering staff. It can also be the basis for further research on application compared to other material and design solutions and, depending on the issue, different combination of aggregated methods.

Selection of materials is pivotal for the success of engineering design applications. Their proper selection is an exhaustive task as a result of the presence of a wide range of material alternatives and performance attributes. Thus, this research proposes an integrated multi-criteria decision-making method for the sake of evaluating a set of material alternatives. The material alternatives are assessed with regards to their surface hardness, core hardness, surface fatigue limit, bending fatigue limit, ultimate tensile strength, and cost. The weights of attributes are obtained based on criteria importance through inter-criteria correlation (CRITIC) algorithm. This research then employs six types of multi-criteria decision-making algorithms to rank the material alternatives. Average ranking algorithm is then applied to generate a full consensus prioritization of material alternatives. A sensitivity analysis is also carried out to determine the most robust and sensitive multi-criteria decision-making algorithm.
