Earth Block

Soil has been used as a building material in different forms, such as mud, adobe, rammed earth, and bricks. Compressed Stabilized Earth Block (CSEB), a form of soil blocks with different additives including cement, fly ash, and lime, is a sustainable building material with many advantages compared to other conventional building materials. The usual practice of past researchers in producing CSEB was to add different materials like sand to the soil to control its clay and silt (finer) content. A high level of finer content is not desirable when it comes to the strength and durability of CSEB. This study proposes to reduce/ extract the finer content in the soil by washing it using a conventional concrete mixing machine.

Earth Block

Two of the primary waste components of the Phosphates benefaction process, sand and clay have been used as building materials for thousands of years. A process known as rammed earth has been used extensively around the world in buildings that have lasted for centuries. Because earth is the main ingredient in rammed earth it has recently enjoyed new popularity as a so called “green” building material. In a similar process earth is compressed into blocks which are then used in the same way as conventional masonry units to build walls. In the compressed earth block [CEB] method, individual units can be manufactured and stockpiled for later use rather than being fabricated on site as in the rammed earth process. This research project will investigate the potential use of waste clay and tailing sand from the phosphate benefaction process as the primary ingredients in compressed earth blocks for commercial and residential construction projects.

The extraction of building materials from their resources through harvesting, preservation, and utilization has become a significant segment of human contribution to the global ecosystem since the industrial revolution. Bamboo is the world's fastest-growing woody plant, and bamboo grows multiple times quicker than most species. Housing is one of the focused demands for bamboo, and as a result of the current scarcity of home units, the demand for bamboo is increasing. Bamboo building construction is portrayed by a basic edge approach like that applied in traditional building design and construction. Applying bamboo as an environmentally friendly material is seen as a movement towards creating a sustainable environment and reducing greenhouse emissions. The need to employ government policy in addressing the production and application of bamboo is reported, and the challenges of bamboo in the global market are highlighted in this chapter.

Concrete is one of the significant building materials in the field of construction which plays an important role that it provides strength and durability properties to the structure. In recent days, modern construction is to improvise the above mentioned properties of concrete with the available sustainable building materials. Self consolidating concrete (SCC) has the ability to make a viscous concrete which can be considered as the pump able concrete with no segregation and compacted itself by its own weight. In this study, fly ash based SCC of grade M40 (1:1.85:1.14) was considered to produce RCC beams of cross section 150 x 200mm of length 1800mm. In order to increase the strength of SCC and to minimize the effect of micro cracks in the RCC beams, hybrid fibers which compose of steel and polypropylene fibers were added into the concrete mixes. Totally 12 beam specimens were prepared with fiber reinforced SCC to check the structural behavior of RCC beams. Finite element modeling software package of ANSYS was used to analyze the structural behavior of RCC beams numerically and the results were compared with the experimental results. From the experimental investigation, the seismic behavior of RCC beams under varying loading condition was examined such as ductility factor, energy absorption capacity and stiffness degradation of the beams.

Properties Of Soil

Earth represents an ecological building material that is thought to reduce the carbon footprint at a point in its life cycle. However, it is very important to eliminate the undesirable properties of soil in an environmentally friendly way. Cement-stabilized rammed earth, as a building material, has gradually gained popularity due to its higher and faster strength gain, durability, and availability with a low percentage of cement. This paper covers a detailed study of hollow compressed cement-stabilized earth-block masonry prisms to establish the strength properties of hollow compressed cement-stabilized earth-block masonry. The test results for masonry prisms constructed with hollow compressed cement-stabilized blocks with two different strength grades and two earth mortars with different strengths are discussed.

Coconut palm wood is commonly regarded as a sustainable building material. Nonetheless, its adoption as a green building material by the construction industry is limited, particularly in West Africa. This paper analyses the impediments to the effective adoption of coconut palm wood in residential building construction. The research data was collected from literature reviews, expert-based surveys, and semi-structured interviews with specialists from the construction sector, African Timber Organization, governmental institutions related to forestry and construction, university professors, and researchers in the areas of sustainable building materials and construction. Thirteen crucial impediments were identified and an integrated evaluation of the impediments was conducted using the Interpretive Structural Modelling (ISM) technique to examine the hierarchical structure of the relations between the impediments. A further technique, Cross-impact Matrix Multiplication Applied to Classification (MICMAC), was used to categorize the impediments from a driving to driven perspective. This categorization provides a unique profile for the impediments, which is different from that of conventional evaluation techniques for evaluating impediments. The findings of this paper offer useful guide to practitioners and policy makers in formulating effective policies, regulations, and standards that will promote the development and wide adoption of coconut palm wood in the construction industry.

The use of earth as a building material, in different forms, such as unburnt and burnt bricks, rammed earth, mud blocks, and soil blocks, is a common practice globally. This study is focused on soil blocks stabilized with cement which are referred to as Cement Stabilized Earth Blocks (CSEBs). The strength and durability of CSEBs are primarily governed by the amount of silt and clay content (finer) in the soil. Many researchers have shown that low finer content improves the properties of CSEB and they have altered the finer content by adding different additives. The current study used a washing method to reduce the finer content and fly ash was utilized as finer to re-fill the soil to the required finer content amount. Also, soil grading was modified by adding larger particles that were separated from the same soil to fit the soil grading to the optimization curves mentioned in the literature. The finer content was changed to 5%, 7.5%, and 10%. Blocks were made by stabilizing the soil with 6%, 8%, and 10% cement and with the size of 150mm×150mm×150mm. The results revealed that fly ash addition up to 10% improves the properties of CSEBs and compressive strength changes from 4.28N/mm2 to 13.43N/mm2.

Unfired earth is a traditional building material, but it is less used than other building materials, such as concrete or steel. But the use of unfired earth is experiencing a renaissance. ammed earth is a type of unfired earth and is usually used for load bearing structures. This paper descries an experimental determination of the tensile bending strength and compressive strength of the rammed earth specimens with known compositions. Mechanical properties are dependent on these compositions (kind of clay, amount of clay, amount of mixture water). Laboratory specimens were produced without inorganic binders or fibrous admixtures. We observed higher tensile bending strengths and lower compressive strengths in specimen mixtures containing more clay. The obtained results were evaluated in a context of a previous research. The results were also compared with results published by another author.
