Featured Project: Evaluation of Flyash & Slag

Porto Website Template

R&D Development Project between Clyde Bergemann and Lafarge.


To develop a Cementitious blending facility making use of dense phase pneumatic transfer systems with no requirement for separate blending facilities. Such concepts had been used in non ferrous processing though never for blending cements.


Jointly funded and jointly managed project to test accuracy of dense phase blending for cement with both fly ash and slag.


  • Blend accuracy and product dispersion met all key criteria and compared favourably with other blending technologies
  • Deemed suitable for high volume continuous blending of materials
  • Led to the investment in a full scale blending facility at a Lafarge import terminal
