The spacers are left in place for the pour to keep the reinforcing in place, and become a permanent part of the structure. The main categories of rebar spacers are Linear Spacers section profiles, H section profiles, or other 3 dimensional shapes , Point Spacers wheel spacers, various tower or chair like shapes You can also divide the rebar spacers in two raw materials categories Concrete spacers Plastic spacers The concrete spacers have the advantage of the same raw material which will improve the watertightness and strength of the concrete. Plastic spacers have the advantage of the low cost production and fast processing. This was the inspiration for a Dutchman who started producing concrete spacers with plastic clips in about 1995. This invention made working with concrete spacers more profitable and easy. Function The engineering study of every concrete construction , whether it is a building, a bridge , a bearing wall or other structure, predicts the positioning of steel rebars at specific positions in the volume of concrete predicted cover of steel reinforcement bars . This cover typically varies between 10mm and 100mm. The statics of every concrete construction are designed in such a way that steel and concrete properties are combined in order to achieve the maximum possible strength for the particular construction e.g. anti earthquake protection as well as to prevent the long term corrosion of steel that would weaken the construction. Rebar spacers secure the correct position of steel, thus assisting in the practical application of the theoretical specifications of concrete construction.

Orphan date February 2009 Industrias Nacionales , also known as INCA , is the leading manufacturer of construction goods in the Dominican Republic . It is headquartered in the Isabela Industrial Zone of Santo Domingo on the outer banks of the Isabela River. History INCA began as a nail factory in Santo Domingo after being acquired by Luis Garcia San Miguel in 1947. It was during the regime of dictator Trujillo that Luis Garcia expanded the factory s capabalities by making it a producer of wire mesh and iron gates. In 1974, Luis Garcia s son, Francisco Garcia Crespo, took over the company and began a process of vertical integration and expansion. This was symbolized with the introduction of new products and processes such as barbed wire and galvanizing capabilities. By 2001, INCA expanded into the steel rebar business with the purchase of a state of the art steel rolling mill. The rolling mill is located 23 kilometers north of Santo Domingo in the Juan Pablo Duarte highway. In 2007, INCA merged with Gerdau resulting in a 49 holding share for Gerdau and 51 for INCA. Business INCA now produces a wide range of construction products but is mainly focused on the production and distribution of steel rebar, PVC pipes and fittings, galvanized sheets, and nails.

Unreferenced date December 2009 In a bending Beam structure beam , a point is known as a point of contraflexure if it is a location at which no bending occurs. In a bending moment diagram, it is the point at which the bending moment curve intersects with the zero line. Knowing the place of the contraflexure is especially useful when designing reinforced concrete or structural steel beams and also for designing bridges. Flexural reinforcement may be reduced at this point. However, to omit rebar reinforcement at the point of contraflexure entirely is inadvisable as the actual location is unlikely to realistically be defined with confidence. Additionally, an adequate quantity of reinforcement should extend beyond the point of contraflexure to develop bond strength and to facilitate shear force transfer.

A cover meter is an instrument to locate rebar s and measure the exact concrete cover . Rebar detectors are less sophisticated devices that can only locate metallic objects below the surface. Due to the cost effective design, the pulse induction method is one of the most commonly used solutions. Method The pulse induction method is based on electromagnetic pulse induction technology to detect rebars. Coils in the probe are periodically charged by current pulses and thus generate a magnetic field. On the surface of any electrically conductive material which is in the magnetic field eddy current s are produced. They induce a magnetic field in opposite directions. The resulting change in voltage can be utilized for the measurement. Rebars that are closer to the probe or of larger size produce a stronger magnetic field. Modern rebar detectors use different coil arrangements to generate several magnetic fields. Advanced signal processing supports not only the localization of rebars but also the determination of the cover and the estimation of the bar diameter. This method is unaffected by all non conductive materials such as concrete , wood, plastics, bricks, etc. However any kind of conductive materials within the magnetic field will have an influence on the measurement. Advantages of the pulse induction method high accuracy not influenced by moisture and heterogeneities of the concrete ref name L. Fern ndez Luco RILEM TC 189 NEC, 2005 L.

Image Flow Test before.JPG thumb 300px The cone filled with concrete, prior to lifting. Image Flow Test after.JPG thumb 300px The diameter of the resulting flow is measured. The flow table test or flow test is a method to determine the consistence of fresh concrete . Application When fresh concrete is delivered to a site by a truck mixer it is sometimes necessary to check its consistence before pouring it into formwork . If the consistence is not correct, the concrete will not have the desired qualities once it has set, particularly the desired strength. If the concrete is too pasty, it may result in cavities within the concrete which leads to corrosion of the rebar , eventually leading to the formation of cracks as the rebar expands as it corrodes which will accelerate the whole process, rather like insufficient concrete cover . Cavities will also lower the stress the concrete is able to support. Equipment Flow table with a grip and a hinge, 70 cm x 70 cm. Abrams cone, open at the top and at the bottom 30 cm high, 17 cm top diameter, 25 cm base diameter. Water bucket and broom for wetting the flow table. Tamping rod, 60 cm height Conducting the test The flowtable is wetted. The cone is placed on the flowtable and filled with fresh concrete in two layers, each layer 25 times tamp with tamping rod. The cone is lifted, allowing the concrete to flow. The flowtable is then lifted up several centimeters and then dropped, causing the concrete flow a little bit further. After this the diameter of the concrete is measured. See also Concrete slump test Duff Abrams Self consolidating concrete cone should be placed in centre of table.

Crosshole sonic logging CSL is a method to verify the structural integrity of drilled shafts and other concrete Deep foundation piles . The CSL method is considered to be more accurate than Pile integrity test sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage. This method provides little indication of concrete soundness outside the cage. Also known as Crosshole Acoustical Testing, CSL normally requires steel preferred or Polyvinyl chloride PVC CSL access tubes access tubes installed in the drilled shaft and tied to the rebar cage. After the shaft is drilled, and before the rebar cage is placed in the hole, the CSL access tubes are attached to the interior of the rebar cage and then the cage is lowered into the hole and the concrete is placed. Steel CSL access tubes CSL tubes are preferred over PVC tubes because studies have shown that PVC tubes tend to debond from the concrete due to the heat of hydration process of concrete, resulting in erratic CSL test results. ref cite journal last Hadjuk first Edward L. coauthors Ledford, D.L., and Christopher, W.R. title PVC and Steel Access Tube Debonding during Sonic Logging Testing for the SC 170 Bridge Replacement Project journal Proceedings of the Deep Foundation Institute 2004 Annual Conference, Vancouver, BC year 2004 ref ref cite journal last Schmauder, M.S. first Gretchen coauthors Steve D.
