Description
1.0209E
Blaine Air Permeability Apparatus, hand-operated.
According to EN 196-6, ASTM C204, BS 4550.
The Blaine Air Permeability Apparatus determines the fineness of Portland cement in terms of the specific surface area expressed as the total surface area in square centimeters per gram of mortar or cement. The Blaine works by drawing a definite quantity of air through a bed of cement exhibiting a definitive porosity value. The number and size of the pores in a prepared bed of definite porosity is a function of the particles’ size and determines the airflow rate through the bed.

- (1) calibrated U-tube manometer,
- Filter papers: 12.8 mm dia. (1000 pcs.)
- Fill oil 50 ml
- Light grease 50 ml
- Plug
