SAND REPLACEMENT IN STRUCTURAL LIGHTWEIGHT CONCRETE-CREEP AND SHRINKAGE STUDIES
THE CREEP AND SHRINKAGE VOLUME CHANGES OF 47 STRUCTURAL LIGHTWEIGHT CONCRETES CONTAINING SEVEN LIGHTWEIGHT AGGREGATES AND VARYING AMOUNTS OF A NATURAL SAND ARE REPORTED. THIS PAPER IS FIFTH AND FINAL IN A SERIES REGARDING THE PARTIAL OR COMPLETE REPLACEMENT OF LIGHTWEIGHT FINES WITH SAND. CREEP AND SHRINKAGE WERE GENERALLY REDUCED WHEN INCREASING AMOUNTS OF SAND FINES WERE USED. DATA ARE PRESENTED WHICH CORRELATE THE REDUCED VOLUME CHANGES TO INCREASING VOLUME OF COARSE AGGREGATE IN THE CONCRETE. THE INCREASE OF COARSE AGGREGATE VOLUME ARISES FROM THE PROPORTIONING PROCEDURES, AND ALSO REFLECTS THE REDUCTION OF WATER, CEMENT, AND FINE AGGREGATES IN LIGHTWEIGHT CONCRETES CONTAINING INCREASING AMOUNTS OF NATURAL SAND. /AUTHOR/
