SAND REPLACEMENT IN STRUCTURAL LIGHTWEIGHT CONCRETE - SINTERING GRATE AGGREGATES

EFFECTS OF REPLACING THE FINES OF THREE STRUCTURAL LIGHTWEIGHT AGGREGATES WITH EQUAL VOLUMES OF NATURAL SAND ARE DESCRIBED. THIS INVESTIGATION IS A CONTINUATION OF PREVIOUS WORK AND EXTENDS TEST DATA TO BROADEN INFORMATION ABOUT AGGREGATES PRODUCED ON A SINTERING GRATE. THE RESULTS ILLUSTRATE IMPROVEMENTS IN BOTH THE PLASTIC AND HARDENED CONCRETES. THE WATER AND CEMENT CONTENTS REQUIRED DECREASED WITH INCREASING NATURAL SAND CONTENT. PHYSICAL PROPERTIES OF THE HARDENED CONCRETES WERE SIGNIFICANTLY IMPROVED, THOUGH THE UNIT WEIGHTS WERE INCREASED MODERATELY.
