Abstract:
GreatWhiteTM cement, developed by CeraTech, Inc., contains 88% industrial waste stream materials while still producing high early strength. The product is specially formulated for use with volumetric, mobile concrete mixers to allow the concrete to be placed almost immediately after mixing so workers have the full 20 to 30 minutes to place, consolidate, and finish the concrete before the material reaches initial set. By minimizing the extraction of raw materials and extending the lives of existing structures, the product can be an important component of a sustainable strategy for rapid repair of concrete structures and pavements. A series of photos illustrates the speed with which pavement repairs can be made.
