Cement Packing for Steam Joints.

Among the more recent Industrial applications of Portland oement 1b its substitution for rubber and abestos preparations in the packing of steam joints, the fact appearing, from extensive practical trials, especially in Germany, that such packing is quite as efficient as those which have hitherto been relied upon, while its cost is much below the latter. Ib practice, the cement is made into a paste with water and spread in a layer from one-fifth to one-half inch thick over the surface of the metal, and the plate or cover to be fixed is now placed in position, and the screws simultaneously sorewed down very slowly. After the layer has been compressed to about one-eighth of an inch in thickness, the screwing is busS ended and the cement allowed to arden for four hours; the screws are then turned further and the edges plastered again with cement. The Joint is completed in about eight hours after the making of the cement.
