A method for repairing damage on a non-friction surface of a carbon brake disc of an aircraft, includes: removal of a damaged region, cutting of a repair material, anti-oxidation modification of the repair material, bonding and curing, and high-temperature heat treatment. The anti-oxidation modification is performed on the repair material without affecting the mechanical properties of the repair material, which improves the anti-oxidation ability of the repair zone and avoids the preparation of an anti-oxidation coating. In this way, only the damage on the non-friction surface is repaired, and there is little effect on the mechanical properties, friction and wear properties and thermal conductivity of the carbon-carbon composite material.

The invention relates to processes for making steel-microfiber reinforced ultra high performance concrete using recycled glass powder and articles made from the same. The invention includes a process of mixing first dry constituents of fine aggregate and cement to yield a first dry mix, followed by mixing with second dry constituents consisting of 2.5-6.0 micron recycled glass powder, silica fume, silica flour, cenospheres, and optionally microinclusions to obtain a UHPC dry mix, followed by adding water only, with further mixing, then adding a superplasticizer admix and a water-reducing admix to obtain ultra high performance concrete paste, followed by adding steel microfibers that are 13 mm0.2 mm.

Disclosed is a method for producing a porous monolithic material from at least one powder, preferably mineral, the method including at least one step of low-temperature compression of a mixture based on powder and at least one solvent, preferably water. The materials produced by the method have improved mechanical properties compared to the prior art materials. The materials for medical application, such as hydroxyapatite, also have improved biocompatibility compared to the prior art materials. Also disclosed are materials produced by the method.

Processes of forming or repairing a structure for use in high temperature applications may include intermixing a sodium nitrite (NaNO.sub.2) additive with a refractory material; and applying the refractory material to a structure surface.

A cementitious composite and cured masonry block made from the cementitious composite. The cementitious composite contains a cement, a non-rubber aggregate, a crumb rubber and at least one of cement kiln dust and limestone powder. The crumb rubber aggregate is extracted from scrap tires after being processed and then mixed in specified percentages with the aggregate, the cement and water, then cured in forms to make the masonry blocks. In the present disclosure sand, which is used in conventional masonry blocks, is at least partially replaced with crumb rubber to produce a sand-free or sand-reduced masonry block that contains crumb rubber. The crumb rubber masonry blocks satisfy the ASTM non-load bearing requirements. The use of crumb rubber decreases the unit weight and increases thermal resistance of the masonry blocks. The use of cement kiln dust or limestone as a partial replacement of cement will lead to decrease in the cost. The use of industrial waste materials, such as crumb rubber, limestone powder and cement kiln dust, will lead to economic and environmental benefits.
