<p>A settable composition is formed by a mixture of a first slurry comprising a sulphoaluminous composition containing 4CaO.3Al2O3.SO3 and water, and a second slurry comprising beta-anhydrite as a source of calcium sulphate, calcium oxide and/or calcium hydroxide and water. The mixture sets to form a hardened mass containing ettringite, but the first slurry has a very long pumping life. A single pack composition is also disclosed.</p> |
