SAND REPLACEMENT IN STRUCTURAL LIGHTWEIGHT CONCRETE - FREEZING AND THAWING TESTS
THE FREEZING AND THAWING RESISTANCE OF FORTY-SEVEN STRUCTURAL LIGHTWEIGHT CONCRETES CONTAINING SEVEN LIGHTWEIGHT AGGREGATES AND VARYING AMOUNTS OF NATURAL SAND FINES ARE REPORTED. THIS PAPER IS FOURTH IN A SERIES REGARDING THE PARTIAL OR COMPLETE REPLACEMENT OF LIGHTWEIGHT FINES WITH SAND. THE SEVEN LIGHTWEIGHT AGGREGATE CONCRETES AND COMPANION SAND GRAVEL AGGREGATE CONCRETE WERE EVALUATED AT NOMINAL COMPRESSIVE STRENGTHS OF 3000 AND 5000 PSI. THE LEVEL OF DURABILITY WAS GENERALLY RAISED WHEN INCREASING AMOUNTS OF SAND FINES WERE USED IN THE 3000-PSI CONCRETES. ALL 5000-PSI CONCRETES WERE HIGHLY DURABLE AND THE USE OF FINES PROVIDED ONLY MINOR IMPROVEMENTS IN THIS CASE. /AUTHOR/
