RECOMMENDED PRACTICE FOR MEASURING, MIXING, TRANSPORTING, AND PLACING CONCRETE

BEST PRACTICES ARE DESCRIBED RATHER THAN COMMON PRACTICES. ALTHOUGH MANY OF THE RECOMMENDATIONS MADE CAN BE USED IN CONNECTION WITH SPECIAL CONCRETES, IT IS NORMAL WEIGHT CONCRETE TO WHICH THEY PRINCIPALLY APPLY. AMONG THE TOPICS COVERED: CONTROL, HANDLING, AND STORAGE OF MATERIALS, INCLUDING POZZOLANS AND ADMIXTURES; MEASUREMENT OF CONSTITUENT MATERIALS; MEASURING EQUIPMENT; BATCHING TOLERANCES; MIXING, INCLUDING READY-MIXED CONCRETE; RETEMPERING OF MIXES; MIXING TIME; AND MIXERS. METHODS OF PLACING SUCH AS HOPPERS, BUCKETS, BUGGIES, BELT CONVEYORS, CHUTES, AND DROP PIPES ARE COVERED. PAVING EQUIPMENT IS ALSO DISCUSSED. SECTIONS ARE DEVOTED TO THE SPECIAL AREAS OF: TRANSPORTING CONCRETE IN REVOLVING DRUM MIXERS; TRANSPORTING CENTRALLY-MIXED CONCRETE; PREPLACED AGGREGATE CONCRETE; TREMIE CONCRETE AND EQUIPMENT; EQUIPMENT AND PROPORTIONING FOR PUMPING CONCRETE; FORMS; CLEANUP AND JOINT PREPARATION; AND FINISHING UNFORMED SURFACES.
