If combined with bonding agent/bridge (slurry) Disbocret^® 713 PCC-Haftbrücke the product is tested as a repair system according to TL/TP BE-PCC of ZTV-ING.

Material Base / Vehicle

2-component, polymer modified, cement-bound dry mortar.

Packaging/Package Size

Dry mortar:
40 kg bag, 18 m³ silo (capacity: max. 32 t)
Mixing liquid:
25 l plastic can, 1,000 l container

Storage

Dry, shelf life: min. 9 months (from date of manufacture); low chromate content: 9 months.

Bulk density

Approx. 1,800 kg/m³

Maximum grit size

4 mm

Apparent density of green mortar

Approx. 2,300 kg/m³

Properties of hardened mortar

(Average value after 28 days)
Bulk density of hardened mortar: Approx. 2,150 kg/m³Compression strength: Approx. 55 N/mm²Tensile strength under flexion: 10 N/mm²
Adhesive tensile strength: > 2.0 N/mm²
Dynamic modulus of elasticity: Approx. 38,000 N/mm²

Suitable Substrates

Concrete.
The average adhesive tensile (pull-off) strength of substrates must be 1.5 N/mm², with a minimum single/individual value of 1.0 N/mm².

Substrate Preparation

The concrete must be sound/stable, clean and free from all loose 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 parting agents (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 fine-grained repair mortar would 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 with tap water to obtain a matt (flat) moist surface aspect, when applying the bonding slurry. Then apply the fine-grained repair mortar onto the bonding slurry, working wet-on-wet.

Preparation of Material

Pour the given quantity of mixing liquid Disbocret^® 716 PCC-Anmachflüssigkeit in a clean vessel.
Add the corresponding quantity of dry mortar gradually, while agitating with a suitable low-speed paddle mixer (agitator; max. 400 rpm) very thoroughly 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. 0.09 parts by weight approx. 3.6 l

Method of Application

Apply the fine-grained 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.
Fast drying, caused by direct sunlight, high temperatures and drying wind/draught must be prevented by suitable protective measures or by aftercare. Formwork must be handled according to state-of-the-art technology.

Layer Thickness

Min. 10 mm, max. 40 mm

Consumption

Dry mortar: Approx. 2.0 kg/m² per mm of thickness.

Workability

Processing time: Approx. 60 minutes at 20 °C.

Application Conditions

Material, atmospheric, and substrate temperature:
Min. 5 °C, max. 30 °C during application and drying.

Tool Cleaning

Immediately after use with water.
