A permeable pavement and cured fiber composition and a related method are provided. The permeable pavement composition includes a quantity of pavement material, and a quantity of cured carbon fiber composite material (CCFCM) configured to be added to the pavement material to produce a reinforced composition having improved characteristics. An example of pavement material includes a pervious concrete material. The method includes providing a quantity of pavement material and adding a quantity of cured carbon fiber composite material to the pavement material to produce a reinforced composition having improved characteristics.

A method for preparing a silane coupling agent/silica/plant fiber composite includes the following steps: S1: pretreating plant fiber; S2: preparing hydrolysate of a silane coupling agent; S3: preparing a silane coupling agent/plant fiber composite; S4: preparing a silica nanoparticle dispersion; and S5: preparing a silane coupling agent/silica nanoparticle/plant fiber composite. Through the covalent interaction among a silanol group (SiOH) formed by hydrolysis of the silane coupling agent, SiOH of the silica, and a hydroxyl group (OH) on the surface of the plant fiber, the present invention enables silica nanoparticles to be grafted on the surface of the plant fiber. Using a hydrophobic film formed by the silane coupling agent, harmful ions are prevented from invading, and the volume stability of the fiber is improved. Using the pozzolanic activity of the silica nanoparticles, the alkalinity and calcium hydroxide content around the fiber are reduced.

A polyester-resin composite monofilament comprises polyester filaments embedded in a crosslinked resin, the monofilament having a length within a range from 5 to 85 mm, a diameter ranging from 0.2 to 1.3 mm, and a porosity of less than 2%. A concrete comprises these monofilaments as reinforcement, and a process for obtaining these monofilaments is disclosed.

The invention relates to a glass-fiber textile structure, characterized in that it has a parylene (poly(para-xylylene)) coating with a thickness of between 5 m and 30 m, preferably between 6 m and 25 m, in particular between 7 and 20 m. The invention also relates to a method for reinforcing a solid material, which comprises introducing such a textile structure having a parylene coating into a fluid base material, preferably a base material comprising water and a hydraulic binder, and curing the base material.

A reinforced, permeable pavement composition, including a first quantity of a porous asphalt material, and a second quantity of cured carbon fiber composite material (CCFCM) particles, the CCFCM particles can have a particle size smaller than 3.35 mm and the composition can have a porosity between 15% and 35%.

A method for making a dry composite material that exhibits contraction in one or more dimensions when initially hydrated includes preparing a mixture of dry, compressible, hydrophilic polymer elements and hydrophobic, thermoplastic polymer, forming the mixture into a mat, heating the mat to a temperature that is greater than the melting-point of the hydrophobic, thermoplastic polymer such that the hydrophobic, thermoplastic polymer melts and forms a continuous phase around the compressible hydrophilic polymer elements, molding the hot mat into a desired shape, and cooling the mat to a temperature that is less than the congealing-point of the hydrophobic, thermoplastic polymer.

Metal wires for use in the reinforcement of a concrete structure. The metal wires included a metal core encapsulated by a galvanized layer of zinc with a protective passivation layer applied thereon. The passivation layer protects the galvanized zinc layer from being depleted by reaction with water, thereby limiting the level of corrosion protection provided. The level of corrosion protection is determined to be satisfactory when a total of 50 grams of the metal wires produce less than or equal to 3.0 cubic centimeters (cm3) of a gas upon immersion in a 1 molar (M) potassium hydroxide solution (pH=14) for 90 minutes. The passivation layer is provided by the use of dry-drawing agents during the drawing process of the metal wires.
