Specific surface area is an important indicator representing the fineness of a dispersed medium or rock. Many physicochemical phenomena involve the degree of dispersion of an object; therefore, specific surface area is an important indicator for studying the properties of dispersed media (such as cement) and the adsorption characteristics and pore saturation properties of rocks. It is widely used in building materials and the geological industry. It mainly consists of a holder, a pressure gauge, and a pump. By evacuating the water in the cylinder to form a negative pressure, the pressure gauge will display the liquid level difference, and the specific surface area of the rock sample can be calculated according to the formula using the liquid level difference.
