The present invention relates to coloured fiber cement products as well as to methods for manufacturing such products. In particular, the present invention provides coloured fiber cement products, which fiber cement products are coloured in the mass, and at least comprise on at least part of their outer surface one or more cured layers of a coating composition, which composition at least comprises a binder and a pigment and/or a filler and is characterized by a pigment volume concentration (PVC) of between about 1% and about 20%. The present invention further provides processes for producing these coloured fiber cement products. Finally, the present invention provides uses of the coloured fiber cement products as building materials. In particular embodiments, the fiber cement products produced by the processes of the present invention can be used to provide an outer surface to walls, both internal as well as external, a building or construction, e.g. as fagade plate, siding, etc.

Methods of preparing engineered cementitious composite precursors include carbonating a fly ash comprising >about 25% by weight of calcium oxide (CaO) and having a water content of >about 12% to <about 18% by weight of water by exposing the fly ash to a first gas stream comprising carbon dioxide to form a carbonated fly ash. A steel slag is also carbonated that comprises >about 40% by weight of calcium oxide (CaO) and having a water content of >about 12% to <about 18% by weight of water by exposing the steel slag to a second gas stream comprising carbon dioxide to form a carbonated steel slag. The carbonated fly ash and the carbonated steel slag are suitable for use as engineered cementitious composite precursors in a bendable engineered cementitious composite composition that further comprises Portland cement, a polymeric fiber, and a superplasticizer.

A composite cementitious feedstock comprises discrete elements. Each discrete element includes mineral rock agglutinates having irregular surface regions and cavities. Super absorbent polymer (SAP) particles and cement particles are disposed on the irregular surface regions and in the cavities. A binder coheres the agglutinates, SAP particles, and cement particles.

A fireplace surround structure is disclosed. The fireplace surround structure includes a mantel portion, a first vertical leg portion and a second vertical leg portion. The first leg portion and the second leg portion extend downward from the mantel portion at opposite ends to form a unitary fireplace surround structure. Each leg portion has a skeletal bar frame with a plurality of bar portions defining a three sided generally rectangular structure. Each of the sides has a lightweight non-combustible board portion attached on the exterior of the frame. The fireplace surround structure is open to one side and mountable on a wall surface. Each board portion is cast from a mix of Portland cement, silica, and cellulose fibers, which are combined and sintered into a flat board structure.

A cementitious composition includes a Portland cement and at least one non-Portland hydratable cement selected from the group consisting of calcium sulfoaluminate cement, a calcium aluminosilicate cement, and calcium aluminate cement, wherein the Portland cement has a content of at least 10 percent based on the total weight of the non-Portland hydratable cement powder, wherein the cementitious composition is free of latex bonding agents, and wherein the cementitious composition is bondable to asphalt. The cementitious composition may also include an aggregate in the form of asphalt millings.
