Maximizing Aggregate to Cement Ratio in Concrete (Phase 2)

In 1999, the New York State Department of Transportation (NYSDOT) sponsored a research project evaluating methods of decreasing the proportions of cement to aggregate in concrete while producing more durable, better performing, cost effective concretes. This earlier research project has explored an innovative mixing technology produce a concrete mix with improved characteristics and more cost effective than conventional concretes. In phase, 2 a new effective spout-fluid bed mixer was developed, fabricated and installed. By that new device, along with optimization of the operation parameters and the micro-structure analysis superior high performance concretes have been made. Those concretes are batter than the concretes made by conventional methods in compressive strength, shrinkage and workability.
