SPIT designs and manufactures bedding resins at its Bourg-Lès-

Valence plant in France's Drôme region.

As an industrial player, Spit has always been proactive in terms of

both quality (ISO 9002 approval since 1987 and ISO 9001:2000

since 2002), and safety (continuous improvement for our staff

and customers).

Its environmental approach won the company ISO 14001

certification in 2008.

Within this concept of applied standards, the SPIT research

centre has developed two resins for rebar bedding applications.

In accordance with section 5 of the ETAG 001 guidelines

and technical report TR 023 concerning post-installed rebar

connections, all bedding resins must have European Technical

Approval (ETA) as of August 1st 2008.

As with all construction products, this ETA entitles the holder to

display the CE marking on the bedding resins concerned.

Design calculation for rebar connections must now comply with

Eurocode 2 and technical report TR 023 concerning post-installed

rebar connections.

This document is complementary to standing rules for non pre-

stressed concrete. Structures loading capacities are determined

within calculation engineers' design studies.

5.4 - USE AND SETTING PROCEDURES

1 Cut the dosing cap to the hole diameter.

2 Set the dosing cap onto the mixer or extension tube.

3 Position the mixer / extension tube clipped with the cap at the end of the hole and inject until the mark appears.

Function

Dosing caps ensure that the resin is located

at the far end of the hole without any air

bubbles to guarantee bedding performance.

Dosing caps are clipped directly on mixers or

extension tubes (see chart on p.8).

Additional injection accessories: 2 dosing caps to cover all the hole diameters:

1 Set the cartridge into the injection toool.

2 Run out a small quantity of resin to obtain an homogenous mixture.

3 Inject from the far end of the hole and fill half of the volume (use an extension tube if necessary). Put a mark on the mixer or extension tube to make sure half of the hole if filled.

4 Release the tool at the end of the resin injection.

5 Install the bar with rotating movement.

6 Wait until the polymerisation is complete to apply the load. This information is available on stickers.

2.5 - RESISTANCE TO CHEMICAL AGENTS

Chemical resistance was determined by exposing resin samples to various chemicals. The samples resistance was determined by visual

observation and classified in three categories: résistant (+) , sensible (o) . non-resistant (-).

Resistant (+) : The samples in contact with the chemical did not show any visible damage, such as cracks, damaged surfaces, broken angles, or significant swelling.

Sensible (o) : to be used with precaution depending on exposure and usage field. The samples in contact with the chemical are slightly attacked.

Non resistant (-) : usage not recommended. The samples in contact with the substance were damaged.

2.6 - DURABILITY TESTS

Durability tests were performed on SPIT EPCON C8 and EPOBAR/EPOMAX in different environments in accordance with ETA guidelines,

Section 5"Bonded anchors" (March 2001 edition), in order to check the influence of these environments on bond strength. The environments

tested are the following:

¬ Immersion in a highly alkaline solution (pH=13.2) during 2 000 hours.

¬ Sulfurous atmosphere for 80 cycles alternating 8 hours in a sulfur dioxide atmosphere and 16 days in a laboratory atmosphere. The sulfur

dioxide atmosphere corresponds to the introduction of 0.67% of SO2 in an room at 40°C, 100 RH (relative humidity); sulfuric acid is

therefore created in contact with resin.

The obtained results for these tests provide a guarantee that the bond strength of the resins is not affected by any of these conditions.

3.4 - SPIT EXPERT CALCULATION SOFTWARE

A new version of the SPIT EXPERT calculation software, in accordance with Eurocode 2 and ETAs rules, can be used to calculate and print a design calculation note for EPCON C8 and EPOBAR/EPOMAX resins, to join to your engineering documentation (download on www.spit.fr).

3.5 - CALCULATION EXAMPLES

Determination of the anchoring length for a bar diameter 12 and an ultimate load to be supported of 35 kN per fixing.

Assumptions :

¬ Concrete C25/30

¬ Diamond drilling/coring

¬ SPIT EPCON C8 resin

¬ rebars layout :

Ultimate bond strength to be taken into account for concrete C25/30 and for installation with diamond coring fbd = 2.7 N/mm² .

Calculation of reference anchoring length Lb,rqd : Lb,rqd =

NRd

Π • Ø • fbd

Lb,rqd =

35 000Π • 12 • 2.7

= 343 mm

Calculation of α2 coefficient dependinf on the cover influence : Cd = min(a/2 ; c1 ; c) Cd = min(100/2 ; 80 ; 80) = 50

α2 = 1 – 0,15(Cd – Ø) / Ø α2 = 0,525 therefore we take minimum value of 0,7

Calculation of design anchoring length Lbd : Lbd = α2 • α5 • Lb,rqd

Lbd = 0,7 • 343 = 240 mm

Calculation of reference anchoring length for : Lb,rqd max =

NRd

Π • Ø • fbdmaximum design resistance of rebar Lb,rqd max

Lb,rqd max =

49 170Π • 12 • 2.7

= 483 mm

Determination of minimum anchoring length Lb,min : Lb,min = max (0,3.Lb,rqd max ; 10 Ø ; 100 mm) Lb,min = max (0,3 x 483 ; 10x12 ; 100 mm) Lb,min = 144 mm

THE ANCHORING LENGTH USED MUST BE THE MAXIMUM VALUE (Lbd ; Lb,min) i.e 240 mm.

Ratings :

¬ NRd : ultimate resistance (N)

¬ Ø : Ørebar (mm)

¬ fbd : Bond stress (N/mm²) depending on concrete strength (see table on page 16)

¬ α2 : Influence of minimum cover (0,7 ≤ α2 ≤1)

¬ α5 : Influence of confinement by transverse compression (α5 = 1)

¬ a : Distance between rebars (mm)

¬ c, c1 : Cover thickness (mm)

3.6 - DESIGN CALCULATION AID TABLES

Tables are provided in the following pages, to determine anchoring depths, depending on the ultimate load of the bar and the strength of the concrete. These tables also indicate the number of bedding operations per cartridge in each case.

4 - Adhesion design calculation

4.1 - FIELD OF APPLICATION

With SPIT EPCON C8 and EPOBAR/EPOMAX resins, the adhesion calculations can be used to determine the anchoring lengths in the case of application without influence of edge or center distances.

Traction tests are generally performed onsite to validate the minimum anchoring lengths shown in the table below.


¬ Characteristic bond strength τRk : 17,85 N/mm2 resulting from confirmed tests and the calculation using the rebar diameter (available for rebar

diameter 8 to 40mm) [trk = τRu,m x 0,75].

¬ Design calculation bond strength τRd

τRd =

τRk

ϒM = 2,16

(ϒM : partial safety factor)

¬ Calculation of the minimum rebar anchoring length

4.3 - ANCHORING LENGTH CALCULATED FROM BOND STRENGTH

Based on the bond strength of SPIT EPCON C8 and SPIT EPOBAR/EPOMAX, the table below shows the minimum anchoring length for a B500B conncrete rebar and concrete class ≥ C20/25.

Fire calculation method according Eurocode 2 : fire verification in terms of resistance : Rd,fi ≤ Ed,fi

Rd,fi design value of the fire-resistance capacity.

Ed,fi design calculation value of the corresponding effects of actions for fire situations; this value can be deduced from the calculation at normal temperature: Ed,fi = ηfi x FRdu

FRdu design strength at ultimate limit state of a bar anchored at depth Ls (mm) - Ambiant temperature conditions.

ηfi overall reduction coefficient taking the variable/permanent load ratio into account: the ηfi value equals 0,7.

This method can be used to verify the design calculations in a fire situation, but must be under no circumstances used as a subsitute for design calculations at ambient temperature, or in other accident situations, if applicable.

The following pages show fire performance in accordance with the ISO 834 fire curve, following tests and the assessment carried out by the CSTB for SPIT EPOBAR/EPOMAX and SPIT EPCON C8 resins.

Nota: Design calculation in a fire situtation is not covered with Technical Application Document (DTA) concerning design in seismic zones.

Environment

SPIT EPOBAR/EPOMAX and SPIT EPCON C8 resins are packed in black cartridges.

This rigid packaging has the following benefits :

¬ Maximum reduction of the quantity of resin disposed of after use: 3 times less remaining resin after use than in other types of packaging (supple pouch cartridge) .

CARTRIDGE

RESIN

HARDENER

PISTON

¬ Prevention of cartridge damage during transportation.

¬ Protection of resin from UV exposure.

¬ Easier re-use after partial use.

¬ Prevention from leakage.

DISPOSAL OF USED CARTRIDGES ON SITE

Like all resins of the market, SPIT EPOBAR/EPOMAX and SPIT EPCON C8 resins cartridges (classification 08 04 09*- Waste of adhesives and sealant containing organic solvents or other dangerous substances) must be disposed of as special industrial waste (with any hardened product disposed of as ordinary non dangerous industrial waste).

MATERIAL SAFETY DATA SHEETS (MSDS)

Material safety datasheets (MSFDS) for EPOBAR/EPOMAX and EPCON C8 resins are available on www.spit.fr.

Research

Our patented resins are designed and manufactured in our factories located in France.

They follow ISO 9001 Quality standards and ISO 14001 Environmental standards.

Thanks to its rigid black cartidge, EPCON C8, EPOBAR and EPOMAX cartridges are shocks resistant and protected against climate issues (UV, humidity...).

The cartridge design has a special plunger which reduces resin waste and limits the quantity of dangerous waste. This is not the case for the supple pouch system*

Our development focus on designing products that use raw materials which have less impact on the environment, reduce waste and ensure all our cartridges can be recycled.

*According to independant laboratory test report.

SPIT reserves the right to modify the characteristics of its products at any time. Photos may showequipment or accessories supplied as an option and not included as standard.
