RELATION BETWEEN DURABILITY OF CONCRETE AND DURABILITY OF AGGREGATES

THE BASIC REQUIREMENTS FOR DURABILITY ARE THE USE OF SOUND AND DURABLE AGGREGATES, AND MAXIMUM RESISTANCE TO THE ENTRANCE OF WATER. THE AGGREGATES PLAY A DOUBLE ROLE SINCE THE RANGE OF SIZES PLAYS AN IMPORTANT PART IN PRODUCING IMPERMEABILITY. THE CHARACTERISTICS OF AGGREGATES WHICH AFFECT THEIR DURABILITY IN CONCRETE, AND THE EFFECTS OF OTHER FACTORS SUCH AS PERMEABILITY, WATER ABSORPTION, ETC., ARE NOT WELL UNDERSTOOD, AND THOROUGH INVESTIGATIONS ARE NEEDED. CONCRETE LABORATORY STUDIES TOWARD THE FORMULATION OF STANDARD TESTS FOR DURABILITY, AND FIELD INVESTIGATIONS TO CORRELATE LABORATORY AND STRUCTURAL EXPERIENCE ARE URGED. OUTLINES FOR RESEARCH WORK ARE PRESENTED.
