Abstract：
Selection of a suitable alternative material from a pool of alternatives with many conflicting criteria becomes a Multi-Criteria Decision Making (MCDM) problem. In the present study, ternary blended mortars were prepared using ceramic tile dust waste (CTD), fly ash (FA), and ground granulated blast furnace slag (GGBFS) as binder components. Crusher dust (CD) was used as a fine aggregate component. Binder to aggregate ratios of 1:3 and 1:1 were prepared considering suitable flow. A total of 16 mortar mixes were cast. These mortars were tested for various conflicting criteria compressive strength, flexural strength, porosity, water absorption, bulk density, thermal conductivity, specific heat, thermal diffusivity, and thermal effusivity whose weightages obtained were 29.09%, 20.08%, 12.77%, 10.60%, 8.74%, 6.74%, 5.54%, 4.47%, and 1.97%, respectively, as per AHP analysis. Later, considering these different criteria and alternate mortars, it was observed that a 1:1 mortar with 20% CTD, 30% FA, and 50% GGBFS (RC20F30G50) is found to be the suitable mortar with the highest relative closeness coefficient of 0.861 and the highest net outranking flow of 0.316 with respect to MCDM techniques: technique for order of preference by similarity to ideal solution (TOPSIS) and preference ranking organization method for enrichment of evaluations (PROMETHEE-II), respectively. The ranking of the mortar in both methods complies with the relative weightages of the criteria and the performance of the mortars with respect to the above criteria.
摘要：
从具有许多冲突标准的替代方案池中选择合适的替代材料成为多标准决策（MCDM）问题。在本研究中,三元混合砂浆是用瓷砖粉尘废料(CTD)制备的，粉煤灰(FA),和磨碎的粒状高炉渣(GGBFS)作为粘结剂组分。破碎机粉尘(CD)用作细骨料组分。考虑到合适的流动,制备1:3和1:1的粘结剂与聚集体的比率。浇注总共16种砂浆混合物。对这些砂浆进行了各种相互矛盾的抗压强度标准测试，抗弯强度,孔隙度,吸水,堆积密度,热导率,比热,热扩散率,和获得的重量为29.09%的热扩散系数，20.08%,12.77%,10.60%,8.74%,6.74%,5.54%,4.47%，1.97%，分别,根据AHP分析。稍后，考虑到这些不同的标准和替代迫击炮，据观察，1:1砂浆与20%CTD，30%FA,与MCDM技术相比，发现50％GGBFS（RC20F30G50）是合适的砂浆，其相对接近系数最高为0.861，净排名最高为0.316：通过与理想解决方案的相似性进行偏好排序的技术（TOPSIS）和用于丰富评估的偏好排序组织方法（PROMETHEE-II），分别。两种方法中砂浆的等级均符合标准的相对重量和砂浆相对于上述标准的性能。
