The dry heat-insulating mix for shotcreting and concrete spraying ShotRock 25 Termo is intended for heat-insulating treatment and strengthening of side walls and roof of mine workings, cement, bricks, stone and other reinforced and non-reinforced surfaces by shotcreting and concrete spraying.
- High insulating effect
- High strength
- Possibility of application of the necessary layer in a single pass
The dry heat-insulating mix for shotcreting and concrete spraying ShotRock 25 Termo is a polymer-mineral fine-grain mix obtained through intensive mixing of graded sand, Portland cement, foamed heat-insulating material and a set of modifying additives
The amount of water necessary for ShotRock 25 Termo dry heat-insulating mix preparation for shotcreting and concrete spraying is determined by the ratio of 0.27-0.29 liters per 1 kg of dry construction mix and is controlled by reviewing the exterior of the previous layer with properties of surface being shotcreted taken into consideration. A layer should not leak, should not shine from excess water. The excess water promotes the layer dulling and future cracks formation.
The thickness of a layer is determined depending on project’s works requirements. The solution is applied continually until the completion or by sections. Before applying subsequent layers, it is necessary to wet the previous layer first, i.e. comply with the treatment method “wet on wet”.
The temperature of the working surface and air must be at least +5ºC and no more than 30ºC. If the temperature is exceeded, ensure intensive wetting of the applied shotcrete (by spraying or steaming).
Works of preparation and application of shotcrete mixes must be performed in accordance with the requirements of the document titled “Technology for the preparation and application of ShotRock shotcrete mixes”.
Dry mix consumption depends on the type of work performed. Preparation of 1 cubic meter of solution requires 1250-1350 kg of dry mix. The mix rebound is less than 5%.
The Portland cement contained in the mix forms an alkali when interacting with water. Avoid contacting the mortar with the skin and mucous membranes. If contact occurs - rinse with clean running water.
Comes in 3-layered paper valve bags with polyethylene liner weighing 20 kg. Bags are put into big bags, 35 bags in each.
Store the construction mix in a dry place with relative humidity of 60%, temperature from –50 to +50ºC. Shelf life in the manufacturer’s packaging is12 months from the date of manufacture.
