摘要： A multi-component inorganic anchoring system, for chemical fastening of anchors and post-installed reinforcing bars in mineral substrates, includes a curable powdery aluminous cement component A and an initiator component B in an aqueous phase for initiating a curing process. Component A further includes calcium carbonate and component B includes an accelerator constituent and water. The calcium carbonate in component A has an average particle size in the range of from 0.5 to 150 μm. Methods can be utilized for using calcium carbonate having an average particle size in the range of from 0.5 to 150 μm in a multi-component inorganic anchoring system to increase load values. Methods can also be utilized for chemical fastening of anchors, such as metal anchors and post-installed reinforcing bars, in mineral substrates, such as structures made of brickwork, concrete, pervious concrete, or natural stone.

摘要： A method and system of additively-manufacturing a structure having a reinforced access opening includes printing, via an additive printing device having at least one printer head, a portion of the structure adjacent to a support surface. The portion of the structure is printed of a cementitious material, and the printed portion of the structure defines an access opening for the structure. Moreover, the method includes providing a void of the cementitious material at a top boundary of the access opening, placing one or more reinforcement members in the void such that the one or more reinforcement members extend across the void, and continuing to print the printed portion of the structure around the void to build up the structure. Thus, the method also includes backfilling the void with a backfill material to incorporate the one or more reinforcement members within the void into the printed portion of the structure.

摘要： A manufacturing process for a one piece tank that involves three steps results in a consistently watertight and structurally stronger unit than previous tanks. The three steps comprise a process for producing the body of the tank, a process for producing a preliminary lid, and a process for producing the final tank. An important step in the process for producing the body of the tank is extending reinforcing steel (rebar) a distance above the concrete walls of the tank. After the preliminary lid is placed into a groove of the tank, the rebar is bent over the lid and a water stop is applied between the walls of the tank and the preliminary lid. The water stop can be any of several forms. In one form, the water stop is in the form of butyl or rubber strip which projects from the walls of the tank above the walls with the rebar. In an alternate form, the water stop is in the form of a gasket of plastic or other suitable material inserted in a groove at the top of the tank. Once the preliminary lid is in place and the rebar bent over the preliminary lid, reinforcing steel (rebar) is bent over the preliminary lid and secured to proper locations. Then concrete is poured to the top and above the sidewalls of the tank until completely full. The resulting cured structure is a one piece water tight tank with an integral water stop.

摘要： Steel reinforcing cables in concrete are protected against corrosion by injecting a carrier fluid and corrosion inhibitors into interstitial spaces between the wires of the cable at a first location along the cable and causing the fluid to pass through the interstitial spaces between the wires of the cable to a second location along the cable. The cable comprises an array of wires confined together and intimately surrounded by a covering material which is engaged with a periphery of the cable so that there are insufficient interconnected spaces between the cable and the covering material to allow passage of fluid longitudinally along the cable outside the cable itself. The method can be used with pre-stressed concrete, with post-tensioned bonded cables and with extruded un-bonded mono-strand cables.

摘要： A composite reinforcing bar is formed by providing a reinforcing material supply of fiber strands ravings; a resin supply bath, and a puller for pulling the resin-impregnated reinforcing material through the resin bath. The material is wound on a holder, while the resin remains unset, rotated about its axis on a drive system so that the material is wrapped around a plurality of guides at spaced positions around the axis such that the fed length of the body is wrapped from one bar to the next to form bent portions of the body wrapped partly around each guide and straight portions between the guides. The guide surfaces are shaped by a machining, blasting or similar process to form projections and recesses which retain a roughness on the outside surface of the reinforcing bar during the curing action while supported on the surface. This arrangement can be used with an optional sand coating to prevent the sand particles from being compressed into the resin or body.
