Blaine Apparatus

How fast cement hydrates, and how quickly it gains early strength, depends on how finely it has been ground. The Blaine air permeability method puts a number on that fineness by timing airflow through a packed bed of powder and reporting it as specific surface area. NextGen supplies digital and automatic Blaine apparatus for cement works, precast plants and construction laboratories, working to EN 196-6 and ASTM C204.

The digital apparatus keeps the classical procedure with an electronic reading, while the automatic version handles fluid aspiration, timing and K constant calibration on its own, which takes operator judgement out of the result. Both are installed and calibrated by our engineers, your team is trained on the procedure, and support continues for the life of the instrument.
