The disclosure provides a ceiling tile including a curable coating composition including 10-50 vol. % inorganic binder, based on the total volume of solids in the dry coating composition, wherein the inorganic binder is an alkali metal silicate or an alkaline earth metal silicate and 50-90 vol. % inorganic filler, based on the total volume of solids in the coating composition, wherein the binder and the filler are not the same and the coating is substantially free of an organic polymeric binder. The ceiling tiles have a backing side and an opposing facing side, and a cured coating layer disposed on the backing side of the panel, the backing side being directed to a plenum above the fibrous panel in a suspended ceiling tile, the cured coating layer including the curable coating composition of the disclosure.

The present invention relates to fiber cement products comprising an inner core material, which inner core material is covered by at least one outer surface layer, characterized in that: —said inner core material has a density of between about 0.4 and about 0.9 g/cm.sup.3 inclusive, and at least comprises cement and between 1 wt % and 70 wt % (with respect to the total dry weight of said inner core material) of a lightweight filler, and—said at least one outer surface layer has a density of between about 0.9 and about 1.4 g/cm.sup.3 inclusive, and at least comprises fibers and cement.

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.

Novel cement, concrete, mortar and grout embodiments for construction. The materials are produced through SCM and quicklime aqueous cement formation reactions. A novel cement is also presented that can be used to form improved concrete, mortar and grout placements. Several novel concrete embodiments are presented that can be used with any aggregate, and for any construction application; including saltwater marine placements.

The present invention relates generally to wall repair compounds such as joint compounds, spackling compounds, and the like used to repair imperfections in walls or fill joints between adjacent wallboard panels. Particularly, the present invention relates to such a wall repair compound comprising a dust reduction additive (DRA) that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust reduction additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. More specifically, this dust reduction additive is of sufficiently lighter shade to not impact the shade of the joint compound upon addition. In one embodiment, this invention relates to a non-foaming dust reduction additive that comprises paraffin and/or micro-crystalline wax-based emulsion.
