Summary
Termites build mounds using spherical units called boluses, selected for properties like granularity and roughness. These material characteristics influence construction and may predict global termite distribution.
Area of Science:
- Zoology
- Materials Science
- Structural Engineering
Background:
- Termite mounds are complex structures studied by various disciplines.
- The fundamental building blocks and material selection criteria of termite mounds remain poorly understood.
Purpose of the Study:
- To characterize the building blocks of termite mounds constructed by Odontotermes obesus.
- To identify key factors influencing material selection and usage in termite mound construction.
Main Methods:
- Controlled experiments were conducted on Odontotermes obesus termites.
- Analysis of the physical and chemical properties of materials used in mound construction.
- Investigation of the self-organized process of bolus fabrication, transport, and assembly.
Main Results:
- Termites utilize biocement to create spherical building units called boluses with a bimodal size distribution.
- Optimal packing is achieved through the specific size distribution of these boluses.
- Material properties such as granularity, hydrophilicity, rigidity, surface roughness, and organic matter content are crucial for handling and mass transfer.
Conclusions:
- The identified material properties and optimal moisture availability are key predictors of termite mound construction efficiency.
- These factors may also influence the global geographic distribution of termite species.

Brick masonry uses bricks as the building blocks and involves building walls from individual bricks laid in mortar. The basic building block of brick masonry is the wythe, a vertical layer of bricks with a thickness of one brick. Within a wythe, bricks can be laid in various courses or patterns, with the most common being the stretcher course, where bricks are laid with their long edge horizontal and face parallel to the wall.
For thicker walls, multiple wythes are bonded together using...

Constructing a concrete masonry wall involves a series of steps designed to ensure durability, stability, and alignment. The construction starts with preparing the base, which includes cleaning the area where the wall will be erected. The next step involves spreading mortar where the first row of concrete blocks will be laid, typically starting at a corner section to help define the wall's boundaries.

Bricks, a fundamental building material, are crafted from fired clay and exhibit a range of shapes, sizes, and colors. The production process starts with extracting local clay or shale, which is then crushed, ground, and screened for a fine texture. The refined material is blended with water, creating a pliable mixture that can be formed into bricks using one of three processes: soft mud, dry press, or stiff mud methods.

01:08Brick Cutting Techniques
734
Brick-cutting techniques involve various tools and methods to shape bricks for construction. A mason's hammer with a chisel-pointed end is used for basic shaping through sharp, precise strikes. For more complex shapes requiring higher precision, a power saw with a water-cooled diamond blade is used.
Cut bricks are categorized by size. Bricks cut to half their original length are called half-bats, while those cut to three-fourths their length are known as three-fourth bats.

Masonry, known for its strength, durability, and aesthetic versatility, encompasses construction with solid stone or man-made units like bricks, clay tiles, terra cotta, and concrete blocks, combined to form structures like walls, floors, and arches. These units are placed in a systematic fashion, known as coursing, and are bound together using mortar—a mixture typically made of water, cement, and sand.

Bricks, a fundamental component of construction, are categorized based on their application and structural characteristics into several types. These include facing bricks, building bricks, hollow bricks, paving bricks, and firebricks. Facing bricks, also referred to as face bricks, are primarily used for both structural support and visual appeal, making their appearance a crucial aspect. In contrast, building bricks are typically used in concealed sections of a structure, such as behind the...
