DOMOGUNIT L
Category
Concrete & Mortar AdmixturesDOMOGUNIT L is a ready for use setting accelerator and waterproofing agent for gunite in liquid form. It complies with EN 934-5 Table 2.
USE
DOMOGUNIT L is used as an accelerator of setting and hardening in liquid and powdered gunite for:
- concrete repair,
- tunnel construction,
- mine tunnel construction,
- open excavations,
- swimming pools,
- thin shell construction etc.
ADVANTAGES
DOMOGUNIT L contributes to the hydration of cement by adding the following advantages:
- increase of watertightness,
- decrease of rebound and dust production,
- better adhesion on wet, damp or dry surfaces and on liquid or powdered gunite,
- increase of layer thickness.
INSTRUCTIONS
Dosage: The dosage of DOMOGUNIT L depends on the desired setting time. The usual dosage is from 2 to 6% on cement weight.
Preparation: The substrate is cleaned from loose particles and wetted if dry. Cement plays a very important role in setting velocity, thus standardized Portland cement of good quality must be used. Aggregates must be of the appropriate grade in order to allow the desired strength and watertightness.
Application:
- In liquid gunite prepared in a mixer (usual cement concentration 350 – 450 kg/m³) DOMOGUNIT L is added in the spray-nozzle during the spraying.
- In dry gunite the aggregates and the cement are premixed (usual cement concentration 300 - 400 kg/m³) and DOMOGUNIT L is added with the mixing water in the spray nozzle during the spraying.
USEFUL DATA
The setting time of gunite depends on the quality and the temperature of the substrate and the ambient, the quantity and quality of cement and the concrete formula and temperature. Tests are recommended in order to determine the dosage as a function of the desired setting time. DOMOGUNIT is alkaline, so preventive measures such as covering of eyes and arms, use of protection cream, are recommended.
Packaging: IBCs of 1500 kg, drums of 285 kg, containers of 20 kg.
Shelf life: At least 6 months in the original sealed containers at a cool spot.
