“…The PCE superplasticiser has a key role in reaching self-compactability and seems to be compatible with the sandy soil employed in the current work, which corroborates with previous research [20,25,41].…”

“…Concerning T-funnel, Okamura [34] suggests a target value of 10 s for self-compactable based mortars. As best to the authors' knowledge, studies on self-compactable earth-based composite are still scarce [20,23,24,41,42] and, in most cases, may not be considered self-compacting due to vibration/compacting needs. Besides, no similar tests of flow diameter and t-funnel were found in the literature survey.…”

A new generation of self-compacting earth-based composites (SCEC) for vertical elements with fully exposed earth, in which the main feature is the elimination of compaction, is proposed in the current work. The first objective was to develop earth-based mixture compositions with locally available raw materials and achieve self-compactability. A Portuguese soil, typically employed in rammed earth construction, was stabilised using cementitious materials and a superplasticiser to ensure flowability. The mixture design studies allowed to achieve flowable fresh composites. Results on the hardened state showed that SCEC presents high compressive strengths (5–14 MPa). The electrical resistivity SCEC increased with time and achieved at least 5600 Ωm at 28 days, while mass loss stabilised after 14 days in a controlled environment room. Additional tests were performed on selected optimal SCEC mixtures: drying shrinkage and water capillary absorption, with promising results. Overall, this work provided initial boundaries for the mixture design and assessment of SCEC and opened the door for further studies on new and novel earth materials construction techniques.

“…Concrete, a mixture of paste and aggregate or rocks, is one of the most widely used building materials. Different kinds are used for building external filled walls, frame structured filled walls, non-load-bearing walls, load-bearing walls, roofs, floors, insulation systems, and so on [3][4][5]. However, as a result, energy consumption is increasing drastically and so is environmental pollution [6].…”

Concrete, one of the sources of energy consumption and carbon emissions, is widely used in the construction industry. The selection of concrete materials raises the question of energy sustainability and turns it into a complex multicriteria decision-making (MCDM) issue. To address this, we present an MCDM framework based on the intuitionistic linguistic hybrid weighted logarithmic averaging distance (ILHWLAD). To begin with, the intuitionistic linguistic numbers are used to deal with the uncertainty and fuzziness of the decision-making process. In addition, in view of the significance and the ordered position of the input arguments, an intuitionistic linguistic hybrid weighted logarithmic averaging distance (ILHWLAD) operator is defined. We, then, initiate the criteria system and present the MCDM framework based on the ILHWLAD to select the finest concrete. A case study involving four alternative materials, namely, autoclaved aerated concrete (AAC), hollow concrete blocks (HCB), expanded polystyrene (EPS), and lime hemp concrete (LHC), is presented to verify the scientificity of the framework.
