Abstract:
One of the governing factors on which safety of civil engineering structure depends on is material used in construction. Materials used for the construction of walls are normally required to possess adequate strength and erosion resistance. The study investigates the suitability of stabilized laterite soils for the production of compressed earth blocks for low-cost housing construction. The materials which are used in this experiment is red soil and some chemicals. The results of the study revealed that the specific gravity, bulk density, moisture content, and plasticity index of the sample sh

Abstract:
Earthen materials are the world’s oldest and cheapest construction materials. Compacted soil stabilised blocks are unfired admixed soil blocks made up of soil plus stabilisers such as binders, fibres, or a combination of both. The manufacturing and usage of cement and cement blocks raises a number of environmental and economic challenges. As a result, researchers are attempting to develop an alternative to cement blocks, and various tests on unfired admixed soil blocks have been performed.

Abstract:
Fly ash and lime have been frequently employed to reduce the swelling potential of expansive soils. Laboratory experiments, scanning electron microscopy (SEM), and X-ray diffraction (XRD) were used in this study to investigate the stabilizing effect of fly ash and lime on expansive soils in the Jianghuai undulating plain area. The comparison was drawn between the variation laws of physical parameters, mechanical properties, microstructure, and mineral composition of expansive soil before and after being stabilized. Experimental results suggest that, after 5% lime is added based on fly ash, the

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

Abstract:
The high cost of conventional cement and sand blocks in Uganda has led to the widespread adoption of alternatives like wattle bricks, compressed earth blocks, and burnt bricks. Compressed earth blocks are a biodegradable, energy efficient, and eco-friendly building material made from damp soil compressed at high pressure. They reduce environmental hazards and deforestation without firewood. Case study methodology was used and deliberatesampling for collection of data. SPSS v20 was used for the analysis.

Masonry units are the major building materials used in construction work. There are several masonry units available in the market today. Some of the widely used masonry units are burnt clay bricks, concrete blocks, fly ash blocks, compressed stabilized soil/earth blocks, geopolymer mud blocks, geopolymer concrete blocks, and so on. These blocks are used for the construction of load bearing structure. To bond two masonry units together, mortar plays a vital role. Fly ash based geopolymer mortar has been used in this study.

AbstractThe study investigated the durability performance of lime and fly ash stabilized lateritic soil blocks subjected to conditions of alternate wetting and drying. A locally available lateritic soil was collected and characterized in the laboratory for its geotechnical properties. The soil was then stabilized using lime and fly ash of various combinations. The blocks were tested for their compressive strength, water absorption and efflorescence. Durability was evaluated by subjecting the blocks to three cycles of wetting and drying and testing its compressive strength. The investigation re

Soil stabilization using cementing materials is a well-known procedure for earth-based building blocks preparation. For the selected binding materials, innovation usually focuses on low carbon systems, many of which are based on alkaline activation. In the present paper, blast furnace slag (BFS) is used as a mineral precursor, and the innovative alkali activator was olive stone biomass ash (OBA). This means that the most important component in CO2 emissions terms, which is the alkali activator, has been replaced with a greener alternative: OBA.

Alternative materials, such as cement-stabilized earth blocks (CSEB), provide new opportunities to make environmentally friendly envelopes. Earth-based construction materials are easy to obtain, abundant in nature, and their use minimizes environmental impacts and improves the thermal performance of bricks. In this work, the thermal properties of CSEB are analyzed, to evaluate their efficiency for building envelopes. It is experimentally determined that cement percentages are between 3% and 9% for the manufacturing of CSEB for non-bearing masonry. The moisture content should be less than 20%,

Abstract Soil is a local material which allows populations in warm regions to better cope with severe environmental conditions. The materials’ performance depends on the chemical and physical nature of the soil. The greatest problem with these materials remains their high sensitivity to shrinkage, and their vulnerability in terms of cracking due to drying. These pathologies may lead to a radical decrease in their mechanical performance. Several works have indicated that the consideration of plant fibers, as reinforcement in earth materials, made it possible to avoid cracking, and, thus, ensure
