7878. Rensing, H. April 14. Bricks; building-blocks.-Sand, slate dust, ashes, or silicious materials are mixed with half-slaked lime, and sufficient water is added to enable the mass to be moulded. On subjecting the articles to the action of steam under pressure in boilers for a few hours, the composition is converted into hard silicate of lime. Ore briquettes are produced by adding finely-divided ore or furnace dust to the mixture of lime and sand.
