SPECIFICATIONS FOR NATURAL AGGREGATES

SPECIFICATIONS CONCERNANT LES GRANULATS NATURELS

THE OBJECT OF THIS WORK IS TO DEFINE THE FIELD OF APPLICATION OF AND ACCEPTANCE CRITERIA FOR NATURAL MATERIALS THAT COULD BE USED IN PLACE OF THE TRADITIONAL AGGREGATES WHICH ARE BECOMING SCARCE. IN ADDITION TO MEETING THIS OBJECTIVE IT IS PROPOSED TO CONSIDER TECHNICAL SPECIFICATIONS FOR CONCRETE AGGREGATES. UP TILL NOW THE WORK HAS BEEN CONCERNED WITH A LITERATURE STUDY, THE PREPARATION OF AN INVENTORY OF THE AVAILABLE RESOURCES AND A STUDY OF AGGREGATE CHARACTERISTICS AND THE WAY IN WHICH THESE CHARACTERISTICS ARE RELATED TO THOSE OF THE MORTARS. THE 1976 WORK WILL BE CONCERNED WITH: - CONTINUATION OF THE STUDY OF LIMESTONE AGGREGATE CONCRETE; - VERIFICATION OF THE RECOMMENDATIONS MADE WITH REGARD TO THE USE OF MARINE AGGREGATES INVOLVING THE MANUFACTURE AND TESTING OF CONCRETES MADE WITH SUCH MATERIALS; - START OF STUDIES CONCERNING THE USE OF PULVERISED SAND WITH RESPECT TO THE ACCEPTABLE CONTENT OF FINE ELEMENTS. THIS RESEARCH PROJECT PARTIALLY SUPERSEDES IRRD RESEARCH PROJECT NO 500414.
