SikaEmaco® T 1200 PG

(former MEmaco T 1200PG)

Rapid setting and hardening, extra high-strength, shrinkage compensated, flowable traffic repair mortar

SikaEmaco® T 1200 PG is a single component, fast setting and hardening pourable repair and bedding mortar that meets the requirements of class R4 according to EN 1504 part 3. SikaEmaco® T 1200 PG is a ready-to-use material that contains sulphate resistant Portland cement (HSR LA), hydraulic binders, well graded sands, specially selected polymer fibres (PAN – polyacrylonitryl) and special additives provide rapid strength build-up even at sub-zero temperatures, improved durability and un-matched low drying shrinkage. When mixed with water, SikaEmaco® T 1200 PG forms a mortar with a fluid or flowable consistency which can be easily applied by hand or machine from 10 mm up to 150 mm thickness.

Application steps

SUBSTRATE PREPARATION

Concrete must be fully cured, clean and sound to ensure good adhesion. All loose traces of concrete or mortar, dust, grease oil, etc. must be removed. Damaged or contaminated concrete should be removed to obtain a keyed surface. Non-impact/vibrating cleaning methods, e.g. shot blasting, sandblasting or high-pressure water jetting are recommended. Aggregate should be clearly visible on the surface of the concrete structure after surface preparation.

Cut the edges of the repair vertically to a minimum depth of 10 mm.

If reinforcing steel is visible, clean to a minimum grade of Sa 2 according to ISO 8501-1 / ISO 12944-4. Ensure back of rebar is also clean. Heavily damaged reinforcement, or when rebar sections have decreased below the safety level, need to be replaced for structural reasons. Ensure a 2 cm rebar cover when installing additional reinforcement.

Although SikaEmaco® T 1200 PG can be applied at ambient temperatures as low as -5°C, the temperature of the substrate should be minimum > 0°C and maximum + 30°C. Frozen substrates need to be defrosted just prior to the application of SikaEmaco® T 1200 PG. Make sure that any metal parts, e.g. reinforcement and manhole frames are defrosted with a temperature above the freezing point. Try to keep the temperature uniform during application and hardening.

In case of fixing manhole frames, set the frames to the required level and install watertight formwork before the application of the material. Inflatable formwork can be used. Fill the formwork with water to test for tightness and pre-soak substrate. Provision must be made for draining of pre-soaking water and air venting during placement. The concrete substrate shall be water saturated, without free standing water, at the moment of application.

In vertical applications use proper formwork, which is sound and watertight. Fill the formwork with water to test for tightness and pre-soak substrate. Provision must be made for draining of pre-soaking water and air venting during placement.

MIXING

It is strongly recommended that only full bags are mixed. Damaged or opened bags should not be used.

First pour the clean tap water in the mixing container and afterwards, while mixing, add approx. 2/3 of the SikaEmaco® T 1200 PG powder slowly and without interruptions to the water. Continue mixing for at least 1 minute. After 1 minute, add the rest of the powder and mix continuously until a homogeneous mortar is obtained.

Mix SikaEmaco® T 1200 PG with a suitable paddle attached to a powerful, slow speed electric drill (max 400 rpm). The total mixing time is 3 to 4 minutes until a homogenous, plastic to fluid consistency is obtained.

Mixing water needed: 2.7 to 3.2 litres per 25 kg bag are required for fluid consistency. Only use clean uncontaminated water.

Note: It is strongly recommended to follow the mixing times before adjusting the consistency by adding extra water! Do not mix more material as can be applied within the pot life of approximately 20 minutes at 20°C. Do not mix SikaEmaco® T 1200 PG with any other material. Only the addition of maximum 30% of clean, well sized gravel is permitted for applications with a thickness over 100 mm.

APPLICATION

Concrete substrates and any metal parts coming in contact SikaEmaco® T 1200 PG need to be defrosted.

The prepared substrate should be pre-soaked, preferably for 24 hours, but at least 2 hours before applying SikaEmaco® T 1200 PG. The surface must be mat-damp, but without standing water.

For optimum curing of the product the temperatures during application of SikaEmaco® T 1200 PG are between -5 °C and +30 °C. Do not apply SikaEmaco® T 1200 PG if the temperature is expected to drop below -5 °C during application or within 24 hours.

The material can be placed behind the formwork or poured into the patch repair area. For better adhesion, the first part of the poured material should be applied into the roughness of the substrate with a stiff brush. The remaining mortar has to be poured immediately after brushing, while the mortar is still fresh.

 

CURING TREATMENT

SikaEmaco® T 1200 PG is basically self-curing. Wet curing is not advised.

When working at sub-zero temperatures, cover SikaEmaco® T 1200 PG with insulation materials or dry cloths until sufficiently hardened, preferably 24 hours or until SikaEmaco® T 1200 PG is to be opened for traffic.

CLEANING OF TOOLS

Tools and mixer must be cleaned immediately after use with water. Cured material can only be removed mechanically.
