DisboCRET 714 PCC I-Grobmörtel 20 - 100 mm
Polymer modified, cement-bound, repair mortar for concrete repairs. Suitable for reprofiling and levelling gradients of trafficable, horizontal concrete surfaces subjected to
dynamic loads.
Field of Application
For reprofiling deep defects and spallings and for levelling gradients on horizontal surfaces as e.g. in car parks/parking garages (application: PCC I).Suitable for producing screeds, reprofiling defective areas and increasing rebar (reinforcing steel rod) protection. Also suitable as concrete repair mortar and for embedding mixed metal oxide titanium anodes for cathodic corrosion protection of reinforced concrete (ferroconcrete).
Material Properties
- Easy preparation and good working properties.
- Low water-cement (w/c) ratio.
- Frost-resistant, de-icing salt resistant.
- Low shrinkage and internal stress (low tension).
- For interior and exterior use.
- For layer thicknesses of 20 - 100 mm, max. grain size: 8 mm.
- Corresponds with mortar class M3 as per German guideline RiLi SIB.
- Mortar for embedding anodes in the field of cathodic corrosion protection.
- Reaction to fire as per DIN EN 13501-1: A2fl-s1 ("nicht brennbar" / non-combustible/inflammable).
- Meets the requirements of DIN EN 1504-3: Structural and non-structural repair.
If combined with bonding agent/bridge (slurry) Disbocret® 713 PCC Haftbrücke the material is tested as a repair system according to TL/TP BE-PCC of ZTV-ING.

40 kg bag, 18 m3 silo (capacity: max. 32 t) - Mixing liquid:
25 l plastic can, 1,000 l container
Storage
Dry, shelf life is min. 9 months (from date of manufacture); low chromate content: 9 months.
Bulk density
approx. 1,800 kg/m3Maximum grit size
8 mmApparent density of green mortar
approx. 2,300 kg/m3Properties of hardened mortar
(Average values after 28 days)Compression strength: approx. 55 N/mm2
Tensile strength under flexion: approx. 9 N/mm2
Adhesive tensile strength: > 2.0 N/mm2
Dynamic modulus of elasticity: approx. 38,000 N/mm2
Static modulus of elasticity: approx. 35,000 N/mm2
Suitable Substrates
Concrete. The average adhesive tensile (pull-off) strength of the substrate must be 1.5 N/mm2, with a minimum single value of 1.0 N/mm2.Substrate Preparation
The substrate must be stable, clean and free from all substances that may prevent good adhesion. Brittle or loose concrete, concrete containing corrosive substances, e.g. chlorides, must also be thoroughly removed by suitable means, along with any remnants of paint, oil, fat/grease or separating agent (formwork oil residues). In the same way, surface laitance should be removed using suitable means. This should be removed to such a depth that the repair mortar can find sufficient adhesion to the treated surface. The edges of spalled or damaged areas must be bevelled (45° – 60°).Pretreat reinforcing steel rods with bonding agent Disbocret® 713 PCC Haftbrücke according to factory specification as corrosion protection.
Pre-wet the concrete to obtain a matt moist (flat) surface appearance, then apply the coarse-grained repair mortar onto the bonding slurry (wet-on-wet).
Preparation of Material
Pour the given quantity of mixing liquid Disbocret® 716 PCC-Anmachflüssigkeit in a clean vessel.Add the corresponding measured quantity of dry mortar gradually while agitating thoroughly with a suitable low-speed paddle mixer (max. 400 rpm) for approx. 3 to 5 minutes, until the mortar is free of lumps and has a homogeneous consistency.
Mixing Ratio
| Dry mortar | Mixing liquid |
| 1 part by weight 40 kg bag | approx. 0.085 parts by weight approx. 3.4 l |
Method of Application
Apply the repair mortar with suitable tool, e.g. shovel, trowel or float, intensively blending (pressing onto it) the material wet-on-wet into the layer of bonding agent/slurry and smoothen the surface, if necessary.Prevent fast drying due to direct sunlight, high temperatures and drying wind/draught by suitable protective measures or by finishing treatment. Formwork must be handled according to acknowledged rule of technology.
Layer Thickness
Min. 20 mm, max. 100 mmConsumption
