A number of progressive, marketing-conscious ready mix producers are already capitalizing on this constriction trend of using white cement by handling white-cement ready mixed concrete. In consequence many projects, especially those in which esthetic considerations are paramount, are using exposed concrete instead of competitive building materials. Availability is proving to be the day to competitiveness; where white-cement ready mixed concrete is not available, bids all too often range up to four times the regular cost of gray cement concrete. Ready mix producers and contractors alike are understandably interested to learn as much as possible about the problems they may encounter in producing and handling white-cement ready mixed concrete. Must handling systems by kept separate? Must special truck mixers be assigned to transporting white-cement concrete? What special wash-out problems can be expected? Is special training necessary for personnel? To find answers to these and allied questions, a staff writer was sent to El Paso, Texas, where El Paso Sand Products, Inc., is providing 35,000 cubic yards of ready mixed concrete for the $17 million, 12 story William Beaumont General Hospital. Approximately 4,000 cubic yards of this concrete will be made with white cement. El Paso Sand is a well established firm in the El Paso market with six plants and 50, eight yard diesel mixers. Vice President and Assistant Manager, Don Baughn, approached the Beaumont Hospital job with routine thoroughness. "We had originally thought triple wash-outs might be necessary to prevent contamination or a mottled concrete," Vaughn said, "but we have found that one good wash out is enough. It is as simple as that. We have not set aside any mixer trucks exclusively to handle white cement concrete. One mixer may carry loads of gray and white concrete the same day. Equipment and people are major factors. We have good people and good equipment."
