The Manual Blaine Air Permeability is an essential equipment when it comes to the determination of the fineness of Portland cement. This measurement is stated in term of the specific surface area which obtained by dividing the total surface area in cm²/g of cement or mortar. Due to its accurate approach, the Manual Blaine Air Permeability ensures results that aid quality control in cement production.

The procedure that is followed in the use of the Manual Blaine Air Permeability is by pulling a fixed volume of air through a layer of cement that has a certain permeability value. The air permeability test is based on the interference between the number and the size of the pores that are in prepared bed and which depend on the particle size distribution. It defines the rate of airflow through the bed, which makes it critical in assessing cement quality.

Meeting ASTM C204, Method A and AASHTO T153 requirements, it enables the laboratories to conduct the tests in a standard procedure as well as accurately. It helps technicians effectively measure cement fineness for predicting the performance in applications such as concreting.

Besides its principal purpose, the Manual Blaine Air Permeability also provides added versatility in a laboratory setting. When used in conjunction with other equipment it offers a complete picture of the cement properties, thus establishing whether the materials meet required standards.

The construction of the Manual Blaine Air Permeability is friendly so that it will be easier to use while still giving accurate results. It has got a strong construction that gives guarantee of its durability thus makes it to be a recommendable tool to any laboratory that deals with cement testing.
