A hydratable cement composition which will bond to both asphalt and cementitious substrates is supplied for the repair of various surfaces. The composition comprises of a combination of Portland cement, calcium sulfoaluminate cement or calcium aluminosilicate, and an alkali metal salt activated pozzolonic powder, wherein the Portland cement content of the hydratable portion of the composition is greater than 20%. The composition is free from latex bonding agents and calcium aluminate. The composition is mixed with water to form a typical cement, mortar, or concrete consistency, placed and allowed to cure. The result is a self-adhering patch to damaged surfaces. The hydratable cement composition may also be used to fabricate items of original construction by casting into molds or forms.

A multi-component resin system can be used for producing a mortar composition based on isocyanate amine adducts for the chemical fastening of construction elements. A mortar composition based on isocyanate amine adducts can be produced from the multi-component resin system. A corresponding method can be used for the chemical fastening of construction elements in mineral substrates, using the mortar composition based on the isocyanate amine adducts.

A cementitious composition of one embodiment, according to the present teaching, includes, but is not limited to, a Portland cement, and at least one other cement from a group comprising, but not limited to, calcium sulfoaluminate cement, a calcium aluminosilicate cement, and calcium aluminate, wherein the Portland cement has a content of at least 20 percent based on the total weight of the non-Portland hydratable cement powder, wherein the cementitious composition bonds to asphalt.

The present application relates to fire resistant compositions, particularly fire resistant compositions comprising an inorganic filler. In particular, the disclosure relates to cladding compositions and composite panels comprising the fire resistant cladding compositions. The disclosure also relates to the preparation of such compositions, composite panels and to their use.
