“…The house has a flat roof to increase radiant cooling (Al-Hinai, Batty, and Probert 1993; Damlūji 1998) and is surrounded by a parapet high enough to cover most of a standing person, mainly for privacy. The upper floors are constructed using a structure made of date palm trunks, cut in half or four, covered with palm leaves matting, supporting the massive layer of mud and small rocks covered with locally made lime-based plaster (Sarooj) (Meddah et al 2020).…”

The use of cooling systems has increased because of drastic changes introduced after the oil revolution in the local architecture by using modern building designs and practices that may not suit Oman's climate. The traditional architecture in this country is characterized by its passive cooling design features, which the Locals fine-tuned through trial and error. These sustainable passive design practices developed over the ages have the ability to provide healthy and comfortable spaces for their occupants while preserving the environment and natural resources. These strategies are still evident in many traditional settlements and buildings in Oman. The present research evaluates the effect of natural ventilation in achieving thermal comfort in traditional Omani houses. For this purpose, a traditional house in a hot-arid climate zone with vernacular architecture typology was chosen as a case study. Computational Fluid Dynamic (CFD) was used to model the house and analyse the airflow and temperature levels in its spaces. The results show the efficiency of such a design to enhance natural ventilation and thermal comfort in similar geo-climatic regions.

“…Although sarooj had been widely used in Oman and the neighboring countries for centuries in a variety of architectural and defensive contexts, its application in these areas has become much more restricted in recent decades. The primary purpose of this research is to enhance the physical mechanical properties of the ancient manufactured Sarooj and develop it into a binding product while also reducing its impact on the environment [13].…”

Despite having several negative effects on human life and the environment, cement is the main component of concrete. Carbon dioxide is released into the atmosphere as a byproduct of cement production. As a result, cement production must be curtailed to lessen environmental impact. Therefore, it was crucial to find a material that could replace cement but wouldn’t harm people or the environment in the process. When compared to cement, burnt clay (or sarooj) is seen as more eco-friendly because of its similar properties and uses. It was investigated in this study whether sarooj could be used to replace cement in concrete at different percentages (0%, 10%, 20%, 30%, and 40%). Several tests, including a sarooj chemical test, a slump test, a water absorption test, a rebound hammer test, a compressive strength test, and a flexural strength test, were performed on the concrete to ascertain its mechanical qualities. Based on the results, 10% sarooj is the best option because it outperforms 20%, 30%, and 40% in compressive and flexural strength, respectively.

“…To overcome these economical and environmental issues, and promote sustainability in the concrete industry, several alternative binding materials such pozzolanic and supplementary cementitious materials (SCMs) are broadly used at this time in concrete as a partial replacement of clinker cement. These pozzolanic and SCMs could not only enhance concrete` sustainability but also mechanical properties and durability performances of concrete/mortar material [1][2][3][4][5]. Pozzolanic and SCMs might be natural or artificial.…”

“…Although the artificial ones derived from industrial by-products may contribute more to sustainability, the natural ones, including calcined clays may also reduce energy consumption, reducing both the GHG released and the cost. Recent studies by the authors demonstrated that clays procured from identified locations within the Sultanate of Oman have an impressive potential to be used as a cementitious/pozzolanic materials in mortar production as a partial replacement of OPC [5][6][7]. Although the sultanate of Oman is very rich with natural minerals, it is fully depending on artificial pozzolans that are imported with all the economic and environmental consequences.…”

The use of natural and artificial cementitious and pozzolanic materials is gaining importance and become an essential component in today's cement-based materials. Supplementary cementitious materials are recognized to provide an added value to concrete/mortar both for mechanical and durability performances as well as to their sustainability with reduced environmental impacts of the construction industry. Developing locally produced natural pozzolans is vital in the efforts towards enhancing the construction industry's sustainability. Locally extracted raw soil from Nizwa city (NZS) in Oman was ground, calcined, characterized, and used at 10%, 25%, 35%, and 50% as partial replacement of ordinary Portland cement (OPC) in mortar mix. The blend mortar was assessed with regard to compressive strength and durability properties. The obtained results indicate a slight reduction in the flow of the blended mixes. An insignificant effect of the NZS replacement on the hardened mortar's density was observed while slightly reduced strength at 1-day and 28-day for some replacement levels. Meanwhile, around a 1% reduction in the porosity and absorption. Blended cement mortar with NZS demonstrated adequate resistance to sulphuric acid and (sulphate + chloride) exposure with lower weight and strength losses compared to the control mortar.
