1. Bulk Density (용적비중)

Bulk Density (용적비중)은 자연상태의 배열을 한 토양의 공극을 포함한 일정부피 중의 건물중(乾物重)을 측정하는 것입니다. 이를 위해 100mL Core, 알루미늄 박 또는 칭량병, 항온건조기, Core용 채토기, 저울 등의 기구를 사용합니다. 토양 시료를 채취하여 건조 후 무게를 측정하고, 이를 토대로 용적비중을 계산합니다.
2. Particle Density (진비중)

Particle Density (진비중)은 토양입자 자체에 의하여 대체된 물의 부피로 토양의 무게를 나누어 측정합니다. 이를 위해 비중병 또는 플라스크, 깔때기, hot plate, 진공펌프, 저울 등의 기구를 사용합니다. 토양 시료를 플라스크에 넣고 탈기 과정을 거친 후 물로 채워 무게를 측정하여 진비중을 계산합니다.

1. Bulk Density (용적비중)

Bulk density is an important physical property that measures the mass of a material per unit volume, including the volume of the particles and the void space between them. It is a crucial parameter in various industries, such as agriculture, mining, and construction, as it affects the handling, storage, and transportation of materials. A higher bulk density generally indicates a more compact and dense material, which can impact factors like packing efficiency, flow behavior, and energy requirements for processing. Understanding and controlling bulk density is essential for optimizing processes, ensuring product quality, and maximizing resource utilization. Careful measurement and management of bulk density can lead to improved process efficiency, reduced waste, and enhanced sustainability across a wide range of applications.
2. Particle Density (진비중)

Particle density, also known as true density or absolute density, is a fundamental property that represents the mass of a material per unit volume of the solid particles, excluding the void space between them. This measure is particularly important in fields such as materials science, geology, and chemical engineering, where the intrinsic properties of individual particles are crucial for understanding and predicting the behavior of materials. Particle density is influenced by the chemical composition, molecular structure, and packing arrangement of the material's constituents. Accurate determination of particle density can provide valuable insights into a material's porosity, surface area, and other characteristics that are essential for applications like filtration, adsorption, and catalysis. Careful measurement and analysis of particle density can lead to improved product design, process optimization, and a deeper understanding of the fundamental properties of materials.
