The present invention generally relates to cementitious material that is a precursor of a magnesium oxychloride cement (MOC) and comprises treated carbon fibers comprising a dispersing agent at least partially coating the carbon fibers and processes for the preparation thereof. The present invention is also related to cementitious material that is a precursor of a magnesium oxychloride cement (MOC) and comprises siliconate and processes for the preparation thereof. The present invention further relates to cementitious material (e.g., pourable, extrudable, moldable and formable cementitious material) and cementitious construction material (e.g., boards, structural laminates, etc.) formed from curing the cementitious material.

Disclosed are an organic binder-based coating; a composite gypsum board containing face and back cover sheets, an outside surface of the back cover sheet bearing the coating; and a method of preparing composite board where the back cover sheet contains the coating on its outer surface. The coating is formed from a composition comprising an alkaline silicate, a solid filler, and optionally, a borate. An enhancing layer can also be applied to the back cover sheet.

To provide a blast furnace slag-type paint using a liquid inorganic material composed of a fluid suspension.

A blast furnace slag-type two-part paint in which a stabilized aqueous suspension containing the following blast furnace slags is contained as the main agent, an alkaline liquid having dissolved therein sodium silicate, sodium carbonate, or potassium carbonate that induces a hydraulic reaction of the suspension serves as the hydraulic reaction inducer, and the main agent and the hydraulic reaction inducer are separately packaged.

<Components of the main agent> (A) 0.5 to 42% by weight of a high-blast-furnace-slag-content blast furnace slag having a blast furnace slag content of 60% or more with respect to the total weight of the blast furnace slag; (B) 0.1 to 20% by weight of a blocking agent containing a phosphorus-containing compound; (C) 0.3 to 5%, preferably 0.3 to 2.5% of a blocking agent differing from a phosphorus-containing compound; (D) water retention agent; others.

An inorganic mortar system for chemical fastening of an anchor in mineral substrates can contain at least one hard aggregate having a Mohs-hardness of greater than or equal to 8. The inorganic mortar system contains a curable aluminous cement component A and an initiator component B for initiating the curing process. Component A contains at least one blocking agent selected from boric acid, phosphoric acid, metaphosphoric acid, phosphorous acid, phosphoric acid, and salts and mixtures thereof. Component B contains an initiator, at least one retarder, at least one mineral filler, and water. The use of at least one hard aggregate having a Mohs-hardness of greater than or equal to 8 in an inorganic mortar increases load values and reduces shrinkage. A method can be used for chemical fastening of an anchor, preferably of metal elements, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete, or natural stone.

A two-component system for forming adhesive bonds or for chemical anchoring comprises a curable binder component A and an activator component B. The component A comprises: A-1) an inhibited hydraulic binder selected from among calcium aluminate cement, calcium sulfoaluminate cement and mixtures thereof; the component B comprises: B-1) a curing activator. At least one of the components A and/or B comprises: V-1) an organic binder; and V-2) a filler having a Mohs hardness of at least 5. The system is an aqueous system which is unproblematical from a health point of view. It is easy to process and quickly attains high strengths.
