Abstract: A brick fabricated from a waste fiber-reinforced polymer (FRP) includes a main body. The main body is formed of a composite. The composition of the composite includes, in parts by weight, 1.0 part by weight of a plurality of furnace slag powders, 0.35 to 0.5 parts by weight of a plurality of glass fiber/polymer particles, 0.02 to 0.5 parts by weight of a plurality of glass powders, and 0.65 to 0.75 parts by weight of an alkali solution. The glass fibers/polymer particles are obtained by crushing the waste FRP. The glass powders are obtained by crushing a waste glass. The furnace slag powders, the glass fiber/polymer particles, the glass powders and the alkali solution are uniformly mixed into a mixture. The mixture is poured into a mold, and then generates a polymerization reaction to form the main body.

Abstract: An anti-blast concrete and a method of fabricating an anti-blast structure member using such anti-blast concrete are disclosed. The composition of the anti-blast concrete according to the invention includes, in parts by weight, 1.0 part by weight of cement, 1.0 to 2.5 parts by weight of fine aggregates, 1.0 to 2.5 parts by weight of coarse aggregates, and a plurality of reinforcing fibers. The weight ratio of the reinforcing fibers to the cement ranges from 0.5% to 3%. The plurality of reinforcing fibers are a plurality of carbon fibers or a plurality of aramid fibers. A test body, made of the anti-blast concrete of the invention, has an average number of times of repeated impacts at an impact energy of 49.0 Joules equal to or larger than 41 times at 28 days of age.

Abstract: A ductile shear reinforced bar layout applied to reinforced concrete shear wall structures comprises several vertical reinforced bars, several horizontal reinforced bars, several connecting reinforced bars, a shear reinforced bar, and several reinforced bars, wherein the vertical reinforced bars and the horizontal reinforced bars are intersected to form a plane, the shear reinforced bar structure and the reinforced bars are firmly disposed on the plane, two adjacent planes are connected by the connecting reinforced bars, pouring concrete to the shear reinforced bar connected on the planes and the shear reinforced bar structure being wrapped around by the concrete are to form the shear wall with the RC. Due to irregular vibrations from earthquake, the surface of the wall is cracked along the directions with larger shear forces. Hence, adding the shear reinforced bar structure can avoid cracks and promoting the ability to anti-vibration.

Abstract: A method for making a reinforcement device for a concrete structure includes the steps of (a) installing a plurality of parallel reinforcement rebars, and (b) embracing the reinforcement rebars with a cable unit by winding the cable unit around the reinforcement rebars. The cable unit has a plurality of wires twisted together.
