THE IMPORTANCE OF CALCIUM SULPHATE REACTION FOR THE USE OF SLAG AND FLY-ASH IN ROAD CONSTRUCTION TECHNIQUES /IN FRENCH/

THE ADDITION BY SCARIFYING OF A CRUSHED SLAG-GRANULATED SLAG-GYPSUM-MIXTURE TO AN INITIAL BESSEMER IRON-ORE GRANULATED SLAG-FLY ASH-GREVECIM-MIXTURE, WHICH WAS UNABLE TO SET BECAUSE OF UNFAVORABLE ATMOSPHERIC CONDITIONS, CAUSED A CALCIUM SULPHATE REACTION IN THE GRANULATED SLAB AND FLY ASH; THE LIME FREED BY THE DICALCIUM SILICATE OF THE CRUSHED SLAG HELPED TO ESTABLISH THE PH FAVORABLE TO THE REACTION; THE LIME NECESSARY FOR THE CHEMICAL REACTION WAS SUPPLIED BY THE GRANULATED SLAG. SETTING OCCURRED AFTER A FEW DAYS. RESULTS OF IN-SITU AND SUBSEQUENT LABORATORY TESTS ARE PRESENTED AND DISCUSSED. /LCPC/RRL/
