Present invention teaches using MGO (magnesium oxide) materials, with the formula of the ingredients as disclosed to create a paste of slurry mixture. A molding and curing process is done by placing a layer of alkaline fiber in a mold with repeated application of the slurry mixture. Additional surface treatment, after hardening/curing, can be done to create surface decorative features, using environmentally friendly water-based coating, to suit clients’ specification.

A cementitious blend composition and a concrete mix composition preferable for making concrete resistant to high temperatures and alkaline conditions, particularly for making durable concrete for constructing an alumina digester tank in an aluminum smelter. The cementitious blend composition includes at least one hydraulic cement, silica fume (SF), and natural pozzolan (NP), wherein a weight percent ratio of at least one hydraulic cement:SF:NP in the cementitious blend composition lies in the range of (24-63):(5-44):(32-40) with the sum of the weight percentages of the at least one hydraulic cement, the SF, and the NP not exceeding 100%. The concrete mix composition comprises water and the cementitious blend composition, wherein a weight ratio of the water to the cementitious blend composition is 0.2-0.5, and wherein the concrete mix composition has a content of the cementitious blend composition of 400-550 kg/m.sup.3.

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.
