According to the present disclosure, methods and techniques for generating preferred concrete block products are provided. The methods and techniques involve providing addition of color to selected section within the blocks (1), as described herein, to generate enhancement effects. Typical applications involve spray applications for color pigment to visually distinct sections of the block (1) on one or more decorative surfaces.

A fireproof, translucent, flexible coated fabric composite materials for use in fire curtains. The composite material meets or exceeds regulatory requirements in terms of fire endurance and allows transmissivity of necessary amounts of light. The process of the present disclosure combines a silica fabric with a special refractory index controlled resin. This unique combination of materials can transform an opaque high temperature fabric into a translucent, and even transparent, composite which as the ability to resist high temperature, flame and smoke penetration that fills a needed gap in technology between visibility and fire resistance in the field of fire and smoke curtains used in civil construction.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier membrane are provided as well.

A method for producing a printed concrete element, in particular a printed concrete block, a printed concrete slab or a printed concrete step, is described, comprising at least the following steps: filling concrete into a mold to form a concrete element; printing at least one surface area of the concrete element with a printing composition comprising a binder A and a dye B, the binder A containing at least one siloxane and at least one silane; and curing the concrete element after printing.

A process for manufacturing a composite part includes introducing an adhesion promoter into the pores of a fibrous preform formed by threads covered with a coating having OH groups on its surface, the adhesion promoter including an electron-withdrawing group G1 that is reactive according to a reaction of substitution or of nucleophilic addition with the OH groups, and a reactive group G2; grafting the adhesion promoter to the surface of the coating by a reaction of substitution or nucleophilic addition of the OH groups on the group G1; introducing a ceramic precursor resin into the pores of the fibrous preform; polymerizing the resin introduced and bonding the grafted adhesion promoter to the resin by chemical reaction between these two compounds at the level of the group G2, and forming a ceramic matrix phase in the pores of the fibrous preform by pyrolysis of the polymerized resin.

Disclosed are methods of protecting porous substrates and/or increasing the peel-resistance of coatings and stains for porous substrates. The methods may include providing a stain or coating comprising a microencapsulated self-healing material; and applying the stain or coating to a porous substrate. Damage to the stain or coating may release the self-healing material at a site of damage, such as a crack or scratch in the stain or coating. The self-healing material may be a polymeric precursor, an unsaturated polyester resin or alkyd, a fatty acid-based natural oil or derivative thereof, or a cross-linkable silane or siloxane monomer or resin. The microencapsulated self-healing material may include a microcapsule having a shell wall that includes a thermosetting polymer or a thermoplastic polymer; the thermosetting polymer may include urea-formaldehyde, melamine formaldehyde, polyurethane, polyurea, or polyacrylate; and the thermoplastic polymer comprises poly(methyl methacrylate), poly(lactic acid), or poly(glycolic acid).
