An anode assembly for the corrosion protection of metal parts embedded in concrete. An ion-conducting material is placed between the metal part that is to be protected and the anode, wherein the ion-conducting material exhibits higher ionic conductivity than the surrounding concrete, thus directing the protective current specifically towards the metal part. A galvanic sacrificial anode may be provided, made, e.g., from zinc and its alloys or aluminum and its alloys. The purpose of the material with higher ionic conductivity than the surrounding concrete is to selectively direct the protective galvanic current towards the metal part that is to be protected. The ion conducting material exhibits 20%, and more preferably 50%, higher conductivity than the surrounding concrete. A suitable ion-conducting material that exhibits ion-exchange properties may comprise tecto-alumo-silicate materials. The anode may be placed in close contact to or may be embedded into the ion-conducting material as well.
Disclosed is a method and an apparatus for measuring the pressure of fresh concrete and similar liquid materials during placement, in which a movable component is displaced under the pressure of concrete or other liquids and is used as an indicator of the pressure exerted by the concrete or liquid material on the device. Mechanical resistance of the movable component is achieved using a calibrated spring or similar mechanical resistance element. The movable part consists of a pressure plate attached to a scaled cylindrical core, calibrated to provide measurements of the external concrete or liquid pressure. The movable component and mechanical resistance element are installed in a casing with flanges to attach the apparatus to the formwork or vessel.

The purpose of the material with higher ionic conductivity than the surrounding concrete is to selectively direct the protective galvanic current towards the metal part that is to be protected. The selective enhanced corrosion protection is especially beneficial for the protection of metal parts that are highly important for the structural integrity of concrete members, such as assembly of pre- or post-tensioning of concrete members, such as anchor-heads. The ion conducting material exhibits 20%, and more preferably 50%, higher conductivity than the surrounding concrete. A suitable ion-conducting material that exhibits ion-exchange properties may comprise tecto-alumo-silicate materials. The anode may be placed in close contact to or may be embedded into the ion-conducting material as well.

A system and method are disclosed for lowering the internal relative humidity inside of a concrete structure by applying a pressurized gas and forcing such pressurized gas into the concrete structure, in turn driving moisture in the pores of the concrete to the exterior of the structure. Pressurized gas is supplied to a network of sealed cavities extending into the face of the concrete structure, ultimately causing the gas to move into the concrete structure through pores and capillaries through the structure, in turn driving moisture in the concrete structure toward the surface. Optionally, a competitive inhibiting agent, such as lithium nitrate, may also be provided to stabilize the concrete structure against future deleterious expansions caused by moisture uptake in the existing ASR gel.

SYSTEM AND METHOD FOR REPAIRING AND STRENGTHENING PIPE WITH INTERNAL HELICALLY WOUND TENSILE REINFORCEMENT
A method for repairing and strengthening pipes by creating a structural reinforced composite liner within the existing pipe. The liner is created by helically winding a tensile reinforcement material on the inside wall of a pipe and encapsulating it in a hardening matrix material. The reinforcement material is helically wound around the inside wall of the pipe by an installation device. The installation device is configured to relieve and/or prevent the development of torsional stress in the reinforcement material that is created by the act of helically winding it onto the inside wall of a pipe, allowing the reinforcement material to lay flat against the pipe wall without twisting or buckling. The structural reinforced composite can be configured to supplement the strength of the existing pipe or to function as a stand-alone pipe within the existing pipe.
Disclosed is a system and method for providing a concrete crack repair system that is capable of providing a pressurized seal that continues to resist the ingress of water even as the crack continues to open and close over time. A compressible seal is provided that may be inserted into and adhesively joined to a machined groove that follows the contour of the crack in the concrete surface. After its installation in the machined groove, grout may be injected into the machined groove below the compressible seal so as to fill the space between the compressible seal and the bottom of the machined groove, which grout may also flow into the groove that is adjacent the bottom of the machined groove, thus allowing pressurized grouting of the crack itself. The compressible seal may also include an interior, hollow chamber that may allow inflation of the compressible seal within the machined groove, thus forming a permanent pressurized seal above the crack.
