“…(Marsh and Kulshreshtha, 2021). They have lower environmental impact, low embodied energy, and improve air quality and thermal comfort (Uzoegbo, 2016;Yang and Wang, 2019;Kasinikota and Tripura, 2021). They require less energy to extract, manufacture, and transport materials, have high load-bearing capacity ( UN-Habitat, 2009;Burroughs, 2010;UN-Habitat, 2012;Kulshreshtha et al, 2020), and are fire and insect resistant (Egenti and Khatib, 2016;Yang and Wang, 2019).…”

“…When interlocking (ICSEB or ISSB), CSEB gains additional benefits because this feature reduces the need for conventional mortar thickness and cement quantity ( UN-Habitat, 2009, 2012, provides greater in-plane and out-of-plane shear resistance, reduces skilled labor requirement, enables self-construction, and cuts construction time (Al-Jabri et al, 2005;Uzoegbo, 2016;Ma et al, 2019;Di Gregorio et al, 2020;Wang et al, 2021). When left unfinished, ICSEB walls should be coated with water-based resin or acrylic varnish to withstand moisture and boost durability (Di Gregorio et al, 2020).…”

As a response to rising housing prices and the high cost of materials in the building and construction industry, a rural prototype house (the Ecofordable House) was built with alternative technologies. The house is located in the western desert zone of Giza, Egypt, and features enhanced vernacular technologies with local materials. Interlocking compressed stabilized earth brick walls, partially reinforced, jack arch and funicular shell roofs, and date palm midribs were employed in an attempt to reduce the usage of steel, fired bricks, cement, and imported wood. The present research evaluates the house’s construction cost-effectiveness and affordability through detailed real-world data and comparisons of material quantities, labor, and costs with those of conventional methods. The “price-to-income ratio” is used as an indicator of affordability. According to the findings, walls cut costs by half, roofs by a quarter, and midribs by two-thirds; the alternatives combined saved 45%, and the house saved a quarter of the cost after adding common expenses. Moreover, less than one-third of steel, fired bricks, and cement were utilized. In the Egyptian context of government-built houses, the prototype would be affordable for most Egyptian income brackets while the conventional house was expensive for the lowest three. The findings provide empirical support for the economic advantages of enhanced vernacular technologies as alternatives and address residential affordability in similar contexts.

“…As shown in Figure 2, the production of the blocks is summarized in five main steps [25]. The first was the preparation of the soil, that is, the soil was sieved on a 5 mm sieve as recommended [26] and then put into bags and transported to the laboratory, then comes the second step which consists of mixing the laterite soil with different proportions of binders, sand and water (Table 1). The amount of water used is the OMC determined during the compaction test on different percentages of GA.…”

“…These methods present limitations to the practice of green building. Firstly, in the world, we have a great heterogeneity in the composition of the raw earth (sandy environmental soil, gravelly soil, laterite soil, and clay soil) [7]. Secondly, the soil differs from one area to another; therefore, soil analysis is necessary to identify which one is suitable for block making [8].…”

In the last decade, several studies have been introduced to the development and use of compressed earth blocks in green building construction. Studying the evaluation of existing cracks in construction builders by these blocks is an important industrial and safety subject in recent research. This objective opens a new field in building construction where we describe the mechanical behavior of compressed earth solid blocks. In addition, we offer a solution to rupture damages presented by the propagation of masonry cracks. This paper aims to explore a numerical study in ABAQUS where we analyze the mechanical properties of this block. We started by investigating the elastic phase for this material and it has been generalized to a study in the plastic regime and rupture for the studied block. The different results of numerical simulation of the studied shape are presented, compared, and criticized.
