Motar thixotrogen agent Usage

Description

Single component, cementitious, high strength , shrinkage compensated, fibre reinforced, thixotropic mortar. Suitable for concrete repairs with layer thicknesses 10-40 mm

Usages

It is suitable for:repairs of damaged structural elements of concrete (beams,columns)concrete cavities due to poor casting and weak vibration repairs of concrete precast elements

Advantages

High strength (R4 class)

It contains pure quartz aggregates

Shrinkage compensating

Impermeable

Formulation rich in cement allows easy placing and finishing

Sprayable

Application Mode

The concrete substrate must be completely clean and structurally sound.

The cavity of  the  surface to be  repaired  should be  at  least 10 mm thick.

The edges where  concrete is  removed,  should  be  cut at an  angle  of  90° and to a  thickness of at  least 10mm

Remove deteriorated concrete or  mortar by hand or mechanical  methods (chisel or high pressure water blasting) ensuring also the appropriate surface roughness.

Reinforcement should be cleaned from rust and any other loose and deleterious  materials  or  add  new  bars if the  existing are no longer appropriate

Before applying THIXOCRETE  the substrate should be  saturated with water

Remove excess water, if any.

In a  clean bucket, initially pour the  minimum amount of  water  indicated, start the  mixer and add THIXOCRETE continuously.  Mix (in low speed) until a  homogeneous, without lumps, mixture is achieved

Then leave  the mixture  to  settle  for 2 – 3 min  and  if  necessary add  water (according to the  amount indicated), and mix again until  the required consistency is  achieved 

Hand mixing of  the  product is  not recommended.

The mortar  can be  applied by trowel or sprayed. 

The final levelling /smoothing of  the  surface, may  only begin once the  mortar  has started to set

After application, the mortar  should  be  properly cured  for  at  least 2  days. During the  summer period  with wet burlaps, spraying water or  curing agents  and  during  winter  period  should  be  protected from low temperatures  with plastic  sheets
