the finished cement. Plant efficiency The cement industry has boosted effi-ciency by concentrating new capital investments in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energy-intensive wet process. Currently, about 80% of the cement produced in the United States is manu-

The dry-mix method appears to be better for low volume placements. The nozzleman should pay great attention in adding the necessary amount of water during shooting operation. Wet-mix method involves the pumping of ready mixed concrete to the nozzle. Compressed air is introduced at the nozzle to impel the mixture onto the receiving surface.
