The present disclosure provides a method for manufacturing of paver block and bricks. The method includes addition of cementitious materials. In addition, the method includes addition of conventional aggregates. Further, the method includes addition of additives. Furthermore, the method includes addition of binding materials. Moreover, the method includes homogenization of the added materials to obtain a first mixture. Also, the method includes addition of a hardener solution to the first mixture. Also, the method includes mixing the first mixture with the hardener solution for 5 minute to 30 minute to obtain a second mixture. Also, the method includes casting the second mixture into a mould to obtain a solidified part. Also, the method includes curing the solidified part in atmospheric air.

A ready-mixed setting type joint compound in which formation of gypsum seeds has been inhibited. A method for controlling a setting reaction by mixing a ready-mixed setting type joint compound with one or more metal ion control agents comprising aminopolycarboxylic acid and/or a salt thereof, and further mixing the setting type joint compound with one or more non-calcium phosphate compounds. The method may further comprise mixing the setting type joint compound with a set activator obtained by blending together a first set activator including a cadmium compound, lead compound and/or zinc compound and a second set activator including a ferrous compound, aluminum compound and/or manganese compound.

The present disclosure is directed to a method of manufacturing gypsum board as well as the resulting gypsum board. The method comprises providing a gypsum slurry with a shrinkage-reducing additive comprising a metal salt of an acid, a silica, or a mixture thereof. As a result, the gypsum board includes gypsum and a shrinkage-reducing additive comprising a metal salt of an acid, a silica, or a mixture thereof. The gypsum board exhibits an area shrinkage of less than 10%.
