Abstract
A SETTABLE CEMENTITIOUS COMPOSITION IS PRODUCED BY MIXING A GROUND MINERAL COMPOSITION CONTAINING THE PHASE 4CAO.3A12O3.SO3, IN THE PRESENCE OF WATER, WITH A SOURCE OF ALKALI METAL OR ALKALINE EARTH METAL UNDER ALKALINE CONDITIONS. IN THE PUMP PACKING METHOD OF STOWING CAVITIES IN UNDERGROUND MINES, AN AQUEOUS SLURRY (1) OF THE MINERAL COMPOSITIONS IS MIXED WITH A SECOND SLURRY (5) CONTAINING CALCIUM SULFATE, LIME, AND, PREFERABLY, BENTONITE AN ALKALI METAL SULFATE AND A SETTING AND/OR HARDENING ACCELERATOR.THE COMPONENTS MAY BE PROVIDED INTIALLY AS A DRY MIXTURE. A PREFERRED MINERAL COMPOSITION COMPRISES OF 4CAO.3A12O3.SO3 IN AN AMOUNT OF FROM 15 TO 68BY WEIGHT AND SIO2, SUCH SIO2 BEING PRESENT SUBSTANTIALLY AS THE PHASE 2CAO.A12O3.SIO2, THE BALANCE IF ANY, OF LESS THAN 1% BY WEIGHT OF FREE LIME, LESS THAN 25% BY WEIGHT OF CAO.2A12O3 AND NOT MORE THAN 10% BY WEIGHT OF 12CAO.7A12O3.
