Provided are a method of manufacturing a three-dimensional textile reinforcement material and a method of constructing a textile reinforced concrete structure using a three-dimensional textile reinforcement material. A two-dimensional grid is bent into a three-dimensional shape using a two-dimensionally woven or knitted textile grid, and the bent grid is coupled with at least one two-dimensional grid, and thus the three-dimensional textile reinforcement material can be simply and easily formed. The three-dimensional textile reinforcement material can be formed by coating the coupled two-dimensional grid and a three-dimensional grid with a thermosetting resin and curing the coupled grids to support a concrete pouring pressure. The three-dimensional textile reinforcement material is formed in a truss material, and the three-dimensional textile reinforcement material with high bending strength can be manufactured, thus a concrete pouring pressure can be supported when a textile reinforced concrete structure is constructed using the three-dimensional textile reinforcement material.

A reinforcing body and a method for its manufacturing. The reinforcing body has at least one reinforcing bar. Each reinforcing bar has a core with a peripheral surface at which a rib structure with at least one rib and at least one depression is provided. The core is formed by at least one first fiber strand embedded in a core matrix. For creating the at least one rib at least one second fiber strand is embedded into a rib matrix, wherein the at least one second fiber strand and the rib matrix are separated by at least one depression in a direction parallel to a longitudinal center axis of the reinforcing bar, such that the at least one second fiber strand is separated into fiber strand sections. The at least one first and the at least one second fiber strand have fibers of different materials.

According to examples, a method may include pouring a fluid ultra-high performance concrete (UHPC) mixture into a cavity, thereby providing a UHPC having at least one exposed surface. The method may include applying a liquid polymer onto the exposed surface of the UHPC, thereby providing a layer of liquid polymer onto the at least one exposed surface. According to examples, the method may include rolling the layer of the liquid polymer layer on the at least one exposed surface of the UHPC with a spike roller having a plurality of extended spikes. In some examples, the rolling may be applied with a predefined amount of pressure to cause the extended spikes to pierce the exposed surface of the UHPC, to incorporate the liquid polymer into the UHPC.

A method of manufacturing cross-corrugated support structures is provided. A mold having a molding surface with a first plurality and a second plurality of corrugations therein is used to introduce corrugations into a flexible, carbonaceous sheet. Cross-corrugations are introduced into the sheet by placing the sheet onto the molding surface, encapsulating the sheet to form a vacuum chamber, and evacuating the vacuum chamber of air. As air is evacuated from the vacuum chamber, the sheet is drawn upon the molding surface causing the sheet to conform to the shape of the molding surface. Thermosetting resin is infused into the sheet and cured causing the sheet to rigidly retain the shape of the molding surface. The sheet is further reinforced by securing at least one support member to the sheet using thermosetting resin.
