DIFFERENCES BETWEEN COHESIVE AND GRANULAR FLOORS

The cohesive soil contains small particles and enough clay for the soil to adhere to itself. When the soil is more cohesive, it is because it has more clay, and is less likely to cause a collapse. Granular soils are formed by coarse particles such as sand or gravel.

When the soil is less cohesive, further steps are needed to prevent a landslide. A measurement system called "compression force" is used to classify each type of soil. That is the amount of pressure needed for the soil to collapse. This value is usually presented in units of tons per square foot.

Part of the process for building a building or road involves analyzing the floor on which the building will be built. Soil environments provide the physical foundation of a building or a way to stand for years. In the engineering aspects of soil composition, they examine the differences in texture, strength and consistency that distinguish cohesive soils from non-cohesive soil environments.

Types of soils from the point of view of soil mechanics.
• Non-cohesive soils: Particles do not tend to stick together, their particles are relatively large, also called granular or rubbing soils (sand, gravel and silt).
• Cohesive soils: There are very small particles where surface electrochemical effects predominate. Particles tend to get together (water / particle interaction) in plastic soils such as clays.
• Organic soils: They are spongy, lumpy and compressible soils. These are prohibited for supports of engineering structures.

Soil mechanics
Soil mechanics, also known as geotechnical engineering, involves the use of soils as engineering materials. This line of study allows engineers to identify suitable ground environments for construction purposes.

The ability of a compact floor and maintain its consistency under pressure determines if it will provide a suitable base for the building. Indeed, engineers examine the physical characteristics of an environmental soil as part of the pre-planning process involved with construction projects.

Texture Differences
Soil texture differences result from the types of rock that make up a particular area. Over time the texture differences appear in the shapes, sizes and arrangement of the particles that make up the soil.

The presence or absence of clay or fine particles determines the cohesive qualities found within a soil environment.
Indeed, clay and finer particle materials act as agents that hold the soil together.

In environments with non-cohesive soils contain little to no clay or fine and cohesive particles soils contain high amounts of clay and fine particles.
