The report describes a research project in which various aspects of transit mixed concrete were studied. Phase 1 describes the work performed in evaluating the effects of extended retention of concrete in a transit mix truck for three hours. Four mixes were evaluated. These were (1) sand and gravel concrete with no admixtures, (2) sand and gravel concrete with admixtures, (3) lightweight coarse aggregate and sand with the moisture content of the coarse aggregate maintained at approximately 15 percent, and (4) the same mix with the moisture content of the coarse aggregate maintained at approximately 30 percent. Phase 2 describes the work performed in the field to determine yield, slump loss, loss of entrained air, water requirements and a comparison of field manufactured specimens to laboratory manufactured specimens. These tests were performed on concrete as was being used on construction projects throughout the State. (Author)
