The present invention relates to construction material compositions comprising at most 55% by dry weight of Portland cement with a high early and late compressive strength. The other main components in the cement are SCMs, limestone, sulfate source and accelerator.

A joint compound formulation is a mixture of a clay, cellulose ethers, expanded perlite, an adhesive, limestone, water, and a surfactant. The surfactant includes an alkyl trisiloxane. In addition a foam stabilizer, sodium dodecyl diphenyl ether disulfonate, may be added to the formulation.

In the field of decorative floor coverings, decorative panels are known having a MDF (Medium Density Board) or HDF (High Density Board) based core layer on top of which a decorative substrate is attached to provide the panels a desired appearance. The invention relates to a panel, in particular a decorative panel, a floor panel, a ceiling panel or a wall panel. The invention also relates to a floor covering consisting of a plurality of mutually coupled panels.

The present invention is directed to processes for making cementitious construction material, in particular magnesium oxychloride (MOC) cementitious construction material (e.g., MOC boards). The processes relate to one or more operations of the overall material production process, including material storage and handling, mixing of materials, curing to form magnesium oxychloride cement, board handling, and/or packaging. Various processes of the present invention involve process control strategies and/or algorithms to provide improved processes for producing construction material. In particular, the processes of the present invention provide improvements in board properties as detailed below (e.g., racking strength), speed of board production, economics of board production, reduction in complexity of manufacture, improvements in consistency of board manufacture, and improvements in quality control.
