Blaine Fineness Apparatus
Product Code : JA-M-8895
The Blaine Fineness Apparatus (SKU JA-M-8895) measures the fineness of cement as specific surface by the air-permeability method: the time taken for a set volume of air to pass through a compacted bed of cement is read on a manometer. The Blaine fineness apparatus has a stainless steel cell with a perforated disc and plunger, and a glass U-tube manometer with ground joint, stopcock and rubber bulb. It is made by JaincoLab for cement testing laboratories.
Specifications
The cell is stainless steel with a 12.70 ± 0.10 mm inner diameter; the perforated disc is 0.9 ± 0.1 mm thick with 30 to 40 holes of 1 mm, and filter papers are 12.70 mm in diameter.

Applications of the Blaine fineness apparatus
Finer cement hydrates faster and gains strength sooner, so its specific surface is a routine quality measure in cement testing.
- Specific surface of Portland and blended cements
- Fineness checks in cement testing laboratories
- Concrete technology practicals in civil engineering courses
- Comparing cement samples from different sources
