Laboratory testing of gravel is an important part of the construction industry, allowing for the assessment of the quality and characteristics of this construction material before its use in various construction projects. Here are some key aspects of laboratory testing of gravel:

1. Physical Characteristics: Laboratories measure the physical characteristics of gravel, such as particle size, density, porosity, and moisture content. These parameters are important for determining the suitability of the material for specific construction tasks.

2. Mechanical Testing: Gravel undergoes mechanical tests, including tests for strength and wear resistance. These tests help determine how gravel withstands loads and wear over time.

3. Composition Analysis: Laboratory research may include an analysis of the chemical composition of gravel to ensure that it does not contain harmful substances that could negatively impact the environment or structures.

4. Corrosion Resistance Assessment: For gravel that will be used in contact with water or in aggressive environments, research is conducted on its resistance to corrosion and exposure to aggressive chemical substances.

5. Comparison with Standards: The results of laboratory testing are compared to industry standards and requirements to ensure that the gravel meets quality and safety standards.

6. Granulometric Analysis: Granulometric analysis helps determine the particle size distribution of gravel, which is important for its proper use in specific mixtures and constructions.

7. Water Absorption Evaluation: Water absorption studies help determine how much moisture gravel can absorb, which can be important in the design of hydraulic structures.

Laboratory testing of gravel ensures a well-informed choice of this construction material and helps ensure its compliance with requirements and standards, contributing to the quality execution of construction projects and the durability of structures.
