DisboCRET 544 PCC I-Grobmörtel 30 - 100 mm

Suitable Substrates

Concrete.
The average adhesive tensile strength of substrates must be 1.5 N/mm², with a minimum individual value of 1.0 N/mm².

Substrate Preparation

Pretreat reinforcing steel rods with Disbocret^® 502 Protec plus as anticorrosion coating according to the manufacturer’s recommendations. Prepare the concrete with Disbocret^® 502 Protec plus according to the manufacturer’s recommendations as a bonding slurry before applying the coarse-grained repair mortar, wet-on-wet.
 
The substrate 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 release/separating agent (formwork oil residues). In the same way, surface laitance (cement stone) should be removed by suitable means. This should be removed to such a depth that the repair mortar will find sufficient adhesion to the treated surface. The edges of spalled or damaged areas must be bevelled (45° - 60°). The substrate must be pre-wetted and should present a matt (flat) surface appearance prior to the application of the coarse-grained repair mortar.

Preparation of Material

The contents of a 25 kg bag of product is gradually mixed into the measured quantity of tap (potable) water leaving behind some amount of water, and agitated with a suitable low-speed paddle mixer (max. 400 rpm) for approx. 3 minutes. Then add the rest of water quantity according to requirements and continue stirring for 2 minutes, until the mixture is free of lumps and has a homogeneous consistency.

Mixing Ratio

Dry Mortar	Water
1 part by weight	approx. 0.09 parts by weight
25 kg bag	2.25 l

Method of Application

Apply the thoroughly mixed product with suitable tool, e.g. shovel, trowel or float, blending the mortar (compressing) wet-on-wet into the bonding 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, e.g. protect scaffolding with foils, moist jute bags or spray with water, for min. 5 days as per ZTV-ING.
Formwork must be handled according to acknowledged rule of technology.

Layer Thickness

Min. 30 mm, max. 100 mm. Higher layer thickness can be achieved by multilayered application.

Consumption

Dry mortar: approx. 2.0 kg/m² per mm of layer/coating thickness.

Workability

Approx. 60 minutes at 20 °C.

Application Conditions

Material, substrate and ambient air temperature:
Min. 5 °C, max. 35 °C during application and hardening.

Tool Cleaning

Clean tools immediately after use with water.

German Certificates

• 4-1081 Testing according to ZTV-ING, TL/TP BE-PCC, application PCC I, P 2149/00-81
