Abstract
A molten reaction product of calcium oxide, silica and aluminum is quickly quenched from a temperature clearly in excess of the .alpha.'-.alpha. inversion in a manner which simultaneously forms stabilized B-phase dicalcium silicate fibers having diameters which do not exceed 15 microns. These fibers are milled into smaller particles which are particularly useful for producing high-strength cement which does not require activation with lime.
