2.3 Methods of Verification

2.3.1 General The assessment of the fitness of the TTM bonded and unbonded post-tensioning system with 4 to 27 strands, for the intended use in relation to the requirements for mechanical resistance and stability in the sense of Essential Requirement 1 of the Council Directive 89/106/EEC has been made in compliance with the Guideline for European Technical Approvals of post-tensioning kits for prestressing of structures, ETAG 013. The release of dangerous substances is determined according to ETAG 013, clause 5.3.1. A declaration was made by the kit manufacturer that the product does not contain any dangerous substances. In addition to the specific clauses relating to dangerous substances contained in this European Technical Approval, there may be other requirements applicable to the products falling within its scope. (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the Construction Products Directive, these requirements need also to be complied with, when and where they apply. The structural members (normal-weight concrete) prestressed by means of the TTM bonded and unbounded strand post-Tensioning system used are to be designed in accordance with national regulations.

The number of strands in a tendon may be reduced by leaving out strands lying radial-symmetrically in the anchor head. The provisions for tendons with completely filled anchors also apply to tendons with only partly filled anchor heads. Into the free drills in the anchor head the short pieces of strands with wedges have to be pressed to prevent slipping out. The admissible prestressing force is reduced per strand left out as shown in Table 7: For further characteristic values of the tendons (mass per meter, ultimate stressing force Fpk) see Annex 5 to 7.

2.4.2 Losses of the prestressing force due to friction and wobble effects

The losses of the prestressing force due to friction and wobbling effects may normally be determined in the calculation by using the friction coefficients and the unintentional angular displacement k (wobble coefficient) given in Table 8 and 8a. The values and k depend on the given duct dimensions and on the maximum distances between the tendon supports. The given value of k only apply if the strands are in the ducts at the time of concreting. If the strands are arranged after concreting, the given values shall only be used in the calculation if the ducts are adequately stiffened during concreting, e.g. by means of PE pipes, or if reinforced ducts are used in connection with smaller distances between tendon supports. For the determination of strains and forces of prestressing steel friction losses PA in the active anchorage zone shall be taken into account according to Table 8.

4. Assumptions under which the fitness of the product for the intended use was favourably assessed

4.1 Manufacturing

TTM bonded and unbonded strand post-tensioning system with 4 to 27 strands is manufactured in accordance with the provisions of this European Technical Approval. Composition and manufacturing process are deposited at the STC.

4.2 Design

Other than all the provisions of p.2.4 of this ETA, also the following provisions shall be considered.

4.2.1 Anchorage recess The anchorage recess shall be designed so as to ensure a concrete cover of at least 20 mm at the protection caps in the final state. Clearance is required for the handling of prestressing jacks. The ETA holder shall keep available information on prestressing jacks and appropriate clearance behind the anchorage.

4.2.2 Reinforcement in the anchorage zone The helix and the additional reinforcement as given in Annexes 5 to 7 shall be adopted. Verification of the transfer of prestressing forces to the structural concrete is not required if the centre spacing and edge distances of the anchorages as well as grade and dimensions of additional reinforcement, see Annexes 5 to 7, are complied with. The forces outside the area of the helix and additional reinforcement shall be verified and, if necessary, resisted by appropriate (transversal) reinforcement. If required for a specific project design, the reinforcement given in Annexes 5 to 7 may be modified in accordance with the respective regulations in force at the place of use as well as with the relevant approval of the local authority and of the ETA holder to provide equivalent performance.

4.3 Installation

4.3.1 General Assembly and installation of the tendons shall only be performed by qualified post-tensioning specialist companies which have the required technical skills and experiences with this TTM Post-tensioning System. The companys site manager shall have a certificate of the ETA holder certifying that he is instructed by the ETA holder and the required knowledge and experience with this post-tensioning system. Standards and regulations valid on side shall be considered. The ETA holder is responsible to inform anyone concerned about the use of this TTM Post-tensioning System. Additional information as listed in ETAG 013, section 9.2 shall be held available at the ETA holder and shall be distributed as needed.


The tendons and the components shall be handled carefully.

4.3.2 Welding Welding at the anchorages is only permitted at the following points:

welding of the end of the helix to a closed ring; for ensuring of the central position the helix may be attached to the bearing plate or anchor body by

tack-welding. After placing the strands in the ducts no more welding shall be performed at the anchorages.

4.3.3 Installation of the tendon The central position of the helix or stirrups shall be ensured by means of tack-welding to the bearing plate or the anchor body or other appropriate mountings. The bearing plate or anchor body and the anchor head shall be in direction vertical to the axis of the tendon. The tendon shall be placed straightforward for the first meter at the anchorage. The connection between trumpet and duct shall be sealed carefully with tape in order to prevent the penetrating of concrete. 4.3.4 Wedging force, slip at anchorages, wedge securing and corrosion protection mass If the calculated prestressing force is less than 0.7 Pm0,max the wedges of fixed anchorages shall be pre-wedged with P0,max (see section 2.4.1). The wedges of all anchorages which are no more accessible during tensioning shall be secured by means of wedge keeping plates and bolts.

4.3.5 Tensioning Before tensioning the minimum mean concrete strength shall comply with the values given in section 2.4.4. It is admissible to restress the tendons by releasing and re-using the wedges. After restressing and anchoring, wedge marks on the strands resulting from first stressing shall be moved to the outside by at least 15 mm. The minimum straight length for tensioning behind the anchorages (strand protrusion) depends on the jack which is used on site. All strands of a tendon shall be stressed simultaneously. This can be done by centrally controlled individual jack or by a bundle jack.

4.3.6 Grouting

4.3.6.1 Grout and grouting procedures (bonded) Grout according section 2.2.7 shall be used. Grouting procedures shall be carried out in accordance with EN 447:1996.

4.3.6.2 Cement grout Cement grout is a stable, uniform mix of cement, additives and water obtained by means of a mechanical mixing process. It is screened and kept agitated in a storage tank until injected into the duct. TTMs prestressing tendons can be injected with:

either a common grout complying with the requirements of the European standards EN 447 (requirements for common grout) and EN 445 (test methods). The grout setting can be delayed to provide a longer grout capacity,

or a special grout, according to the requirements stated in paragraph C.4.3 of ETAG 013.

4.3.6.3 Grease The grease for TTM prestressing tendons shall be a mineral-oil based grease meeting the requirements of paragraph C.4.1 of ETAG 013

4.3.6.4 Water rinse Normally, tendons shall not be rinsed with water.

4.3.6.5 Grouting speed The grouting speed shall be in the range between 3m./min. and 12 m/min.


5. Recommendations for the manufacturer

5.1 Recommendations on packaging, transport and storage

GROUTING OF M, Mep (special application), MX ANCHORAGES Grouting by infilling

Grouting can be carried out by means of a simple padding using expanding mortar, which must respect the proper covering of the metallic parts of the anchorage.

Grouting with temporary cap

The cap is made up of a cover equipped with a sealing gasket fixed to the casting by means of suitable anchorages which vary in length and size depending on the several applications. A special closing disc tightens the sealing gasket and the cap to the grouting. The disc allows to turn the cap into the most suitable position to allow all the air to come out of the vent tube.

GROUTING OF M, Mep (special application), MX ANCHORAGES

Grouting with permanent cap

The cap is made of polyethylene and together with a M, Mep and MX anchorage guarantees a double protection to corrosion. The cap is provided with plugs to guarantee a correct grouting and vent when filling it.
