RECOMMENDED PRACTICE FOR SELECTING PROPORTIONS FOR STRUCTURAL LIGHTWEIGHT CONCRETE

A METHODS IS DESCRIBED AND EXAMPLES CITED FOR PROPORTIONING AND ADJUSTING STRUCTURAL GRADE CONCRETE CONTAINING LIGHTWEIGHT AGGREGATES. IT USES A SPECIFIC GRAVITY FACTOR, DETERMINED BY PYCNOMETER TEST ON THE AGGREGATES, WHICH ACCOUNTS FOR VARIATIONS IN MOISTURE CONTENT OF THE AGGREGATES. A TABULAR FORM IS SUGGESTED FOR SYSTEMATIC CALCULATION OF BATCH WEIGHTS AND EFFECTIVE DISPLACED VOLUMES. EXAMPLES ARE GIVEN FOR ADJUSTMENTS FOR CHANGE IN AGGREGATE MOISTURE CONTENT, AGGREGATE PROPORTIONS, CEMENT FACTOR, SLUMP, AND AIR CONTENT. /AUTHOR/
