STRENGTHS OF SULPHUR-BASALT CONCRETES

THE USE OF ELEMENTAL SULFUR IN STRUCTURAL MATERIALS IS ADVANCED BY DEMONSTRATING ITS VALUE IN BONDING HIGH-STRENGTH WELL-GRADED BASALT AGGREGATES TO FORM SULFUR-BASALT CONCRETES. SULFUR IS AN EXCELLENT BONDING AGENT, AND THE STRENGTH OF A THERMOPLASTIC SULFUR-AGGREGATE MIXTURE DEPENDS, TO A LARGE DEGREE, ON THE STRENGTH AND GRAIN-SIZE DISTRIBUTION OF THE AGGREGATE USED. SULFUR CONTENT OF SEVERAL MIXTURES WAS VARIED TO OBTAIN THE BEST WORKABILITY WITH A MINIMUM OF SULFUR IN EXCESS OF THAT NECESSARY TO FILL THE VOIDS. THE AVERAGE GRAIN SIZES AND GRAIN-SIZE DISTRIBUTION WERE ALSO VARIED TO DETERMINE THEIR EFFECTS ON STRENGTH. UNCONFINED COMPRESSION TESTS OF FORTY-FIVE 6- BY 12-INCH CYLINDERS YIELDED AVERAGE STRENGTHS OF 3,348 PSI TO 10,398PSI. THE HIGHEST STRENGTH SINGLE CYLINDER WAS 10,717 PSI. THE CYLINDERS WERE TESTED FROM 24 HOURS TO SIX DAYS AFTER POURING; AFTER 24 HOURS THE RISE IN STRENGTH WAS VERY SLIGHT. FROM THE RESULTS OBTAINED IT APPEARS THAT SULFUR CAN BE A USEFUL CONSTRUCTION MATERIAL. /AUTHOR/
