The present invention relates to a method for producing a gypsum-containing foamed prefabricated building material and to a gypsum-containing foamed prefabricated building material.

The present invention concerns an improved method of grinding or milling fresh feed (i.e. crushed yet not milled clinker (with or without additions)), using two different grinding agent systems added at specific locations of the cement grinding mill, preferably at two different locations of a cement ball mill, depending on the particle size or fineness of the material to be ground, to reduce the energy needed to achieve a targeted cement fineness or increase the fineness of the cement at constant energy consumption.

Various cement-containing compositions are disclosed, including insulating cement, forms, and prefabricated building materials produced from cement-containing compositions with insulating properties. Some of the preferred embodiments include expanded polystyrene and an acrylic component to provide enhanced insulating properties, or have a lower density, lighter weight, and increased insulating R-value in comparison with other cement-containing compositions.

A process for making a cement, the cement containing a naturally occurring silicate bound in an organic binder, and a metal oxide. An example process includes dissolving the organic binder at least in part, using an effective amount of a chemical activator. An example process also includes providing the silicate to react with other components of the cement. An example process also includes providing the silicate to participate in crystal growth. An example process also includes providing the silicate so that the cement is a structural load bearing cement.
