Renderoc TGXtra*(incorporating DS Technology)

Shrinkage controlled, vertical and overheadcementitious repair mortar system

Uses

Renderoc TGXtra is suitable for hand application to repairs wherelight to medium load bearing is required. Typical applications

would include, but not be limited to, the following:

n Vertical and overhead repairs to restore covercrete.

n General concrete and masonry repairs.

n Voids greater than 10 mm deep.

n Repairs to honeycombing.

n Larger scale repairs where formwork cannot be erected.

Advantages

Renderoc TGXtra features Dimensional Stability Technology - anew materials technology which controls the rate of dryingshrinkage such that, when used correctly :

i. the dimensions of the repair remain stable; and thus

ii. eliminating failure, due to shrinkage cracking.

This in turn leads to a series of associated benefits :

n Cost effective - shrinkage control enables repairs to becompleted right first time.

n Enhanced durability - works in tandem with extremely lowpermeability to prolong effective working life.

n Compatibility - aligns performance closer than ever before,to that of host concrete.

n User friendly - specifically developed to provide an easy-to-apply product, suitable for local conditions.

n Definable performance - positive benefits are easilydemonstrated via a single, simple measurement.

Description

Renderoc TGXtra is supplied as a ready to use blend of dry

powders, which requires only the addition of clean water toproduce a highly consistent, lightweight repair mortar suitablefor general purpose concrete and masonry repairs.

Properties

The following typical results were obtained at a water to powderratio of 0.18.

Test method Typical result

Drying shrinkage to ASTM C 157-937 days : < 300 microstrain28 days : < 500 microstrain

Permeability : < 10 mm(DIN 1048 Part 5)Flexural strength : > 6.5 N/mm2 at 28 days(BS 6319 Pt. 3)Tensile strength : > 2.5 N/mm at 28 days(BS 6319 Pt. 7)Compressive strength : 35 N/mm2 at 7 days(BS 1881 Pt.1161) 40 N/mm2 at 28 daysWater absorption : < 2%(BS 1881 Pt. 121)Note1: 50mm cubes, air cured @ 250C

Design criteria

Dimensional Stability Technology is a major step forwardin the general compatibility of repair mortar systems with thehost concrete, and the control of shrinkage in particular.

Attention to the basic design criteria given below should ensurethat the full benefits of this technology are gained in use :

(i) Recommended limits for a single application are:

Minimum applied thickness : 10 mmOverhead sections : up to 50 mm thickVertical sections : up to 50 mm thick

Small pockets or horizontal : up to 100 mm thickMaximum length : up to 3 m

NOTE : If the repair area exceeds 2.5 m2, considerationshould be given to the use of mass fill by meansof either Renderoc SPXtra* spray applied mortaror Renderoc LAXtra* microconcrete.

(ii) In situations where a substrate/repair barrier is required,or enhanced bond strength/working time is required, or

where the substrate is likely to be permanently wet or damp(e.g. seawalls, quays etc.), Nitobond EP epoxy bondingagent should be used.

(iii) Water addition = 3.6 litres per 20 kg bagUnder no circumstances should part bags be used oradditional water be employed. Either of these two actions

will adversely affect material performance, automaticallyinvalidating Fosrocs standard product guarantee.

Estimating

Supply

Renderoc TGXtra : 20 kg bags

Coverage

Actual coverage rate is approximate, and will be whollydependent upon the general substrate condition. It isrecommended, therefore, that site trials over a typical area

are conducted to determine the likely usage/coverage ratesfor a particular substrate.

Renderoc TGXtra : 1.2 m2 at 10 mm thick(approximately 12.8 litresper 20 kg bag)

Limitations

- Renderoc TGXtra should not be used when the ambienttemperature is below 50C and falling.

- Renderoc TGXtra should not be part mixed, nor part bagsused.

- Renderoc TGXtra should not be exposed to running water

either during application or prior to final set.

- Water ponding is not recommended for curing.

Storage

Shelf life

Renderoc TGXtra has a shelf life of 12 months; if kept in a dry

environment, in its original, unopened packing. If stored inconditions of high humidity and/or temperature, the shelf lifemay be reduced to as little as 4 months.

Standards compliance

Renderoc TGXtra repair mortar system complies with the

following international standards :

ASTM C157-93 : Test for drying shrinkageDIN 1048 Pt. 5 : Test for permeability

BS 1881 Pt. 121 : Test for water absorption

Precautions

Health and safety

Renderoc TGXtra contains cement powders which, when mixedwith water or upon becoming damp, release alkalis which canbe harmful to the skin.

During use, avoid inhalation of the dust and contact with theskin or eyes. Wear suitable protective clothing - eye protection,

gloves and respiratory equipment (particularly in confinedspaces).

The use of barrier creams to provide additional skin protection

is also advised. In case of contact with the skin, rinse withplenty of clean water, then cleanse thoroughly with soap andwater.

In case of contact with eyes, rinse immediately with plenty ofclean water and seek medical advice. If swallowed seek

medical attention immediately - do not induce vomiting.

Fire

Renderoc TGXtra, is non-flammable and thus presents no firehazard.
