In the dynamic realm of sustainable construction, innovation in materials is a compelling strategy to overcome the limitations of conventional products. This study delves into two extraordinary case studies - Rammed Earth and Solar Pavement - to uncover their successes and potential impact. It navigates through a landscape of innovative materials, from research to real-world implementations, focusing on materials that harness nature's gifts and promote eco-consciousness, reducing carbon footprints. This investigation employs a comprehensive methodology, analysing scholarly manifestos, journal chronicles, historical documents, and credible references. It explores material identity, utility, attributes, virtues, vices, construction prowess, industry impact, journalistic coverage, ecological footprints, societal engagement, and tangible projects. Comparisons are made based on sustainability impact, economic viability, and current trends. The findings reveal that Rammed Earth stands as a sustainability luminary, leaving a minimal environmental footprint. In contrast, Solar Pavement holds intriguing promise, requiring further research, development, and audacious pilot endeavours to fully unleash its potential. This saga offers valuable insights into the strengths and weaknesses of these avant-garde materials. Armed with this knowledge, decision-makers in sustainable construction can lead us towards a harmonious future for our built environment.

Optimization of the Granular Mixture of Natural Rammed Earth Using Compressible Packing Model

2023

Rammed earth (RE) construction is an ancestral technique that allows for the building of durable and resistant constructions. RE buildings are sustainable and environment-friendly, and ensure energy optimization during the construction cycle. For these reasons, many of the following RE characteristics are studied: mechanical strength, seismic resistance, and thermal performance. However, the mix design of RE soils has been rarely studied. There is practically no scientific approach that allows for defining precise dosages of clay, silt, sand, and gravel used in RE materials. The broader aim of this article is to determine a scientific mix design method to find an optimal RE granular mixture. The compressible packing model (CPM) is applied to study the effect of every granular class on compactness and define the optimum mixture. Many tests have been conducted such as the Modified Proctor, compression test, and ultrasonic velocity pulse test to evaluate the relevance of this model. The results suggest many granular corrections for RE material that considerably enhance compactness and unconfined compressive strength (UCS). It was found that one granular correction provides a 137% increase in the initial UCS. Therefore, this approach enables the defining of which granular class is to be added or reduced to optimize the mechanical properties of RE.
