IMPROVEMENT OF SANDS FROM THE PARIS REGION

AMELIORATION DES SABLES DE LA REGION PARISIENNE

THE AUTHOR DESCRIBES THE THREE TYPES OF SAND AVAILABLE IN THE PARIS REGION. IN TESTS ON THEIR STABILIZATION, TWO BINDERS WERE USED: RAW 20/40 GRANULATED SLAG AND PRECRUSHED GRANULATED SLAG AND TWO RECTIFYING AGENTS: 0/4 LIMESTONE SAND AND 0/4 SAND FROM CRUSHED CRYSTALLIZED SLAG WITH FAT LIME AS AN ACTIVATING AGENT. MEASUREMENTS WERE MADE OF THE OPTIMUM MODIFIED PROCTOR DENSITY, SIMPLE COMPRESSIVE STRENGTH, IMMEDIATE STABILITY AND FATIGUE. ALL TESTS SHOWED MARKED INFLUENCE OF THE MIX-DESIGN AND GRADING CORRECTION. THE COMBINATION OF PRECRUSHED SLAG BINDER IN THE PROPORTION OF 10 TO 15% WITH A RECTIFYING AGENT CONSISTING OF CRUSHED SLAG IN THE PROPORTION OF 10 TO 20% GIVES THE BEST RESULTS WITH THE SANDS OF THE PARIS REGION.
