Read user manual and safety instructions 2. Examine the hole pattern samples 3. Plan the process and make sure you have everything you need at hand 4. Plan and drill the required hole pattern. Basic principle to keep in mind: object to be cracked must always have 1 or more free sides where it has space to expand and crack to. 5. Mix Ter-Mite with water 6. Pour Ter-Mite into holes 7. Wait until the material has cracked and the process has finished 8. Dismantle the cracked material and transport away if necessary Drilling 1. Use appropriate drill for the job: recommended drill size 32-51mm A bigger drill (40-51mm) will give best results (Ter-Mite expansive force increases with drill size up to 51mm). Drill size of 27-30mm can be used to do modest jobs (use small hole spacing and allow more time). 2. Plan the hole-pattern according to the job. Think how you want the material to crack and examine hole pattern drawings 3. Recommendations for hole depth, spacing and diameter: Material L hole depth Hole spacing cm Hole diameter mm kg / m3 Soft rock 1.0H 30-60 32-51 8-10 Hard rock 1.05-1.10H 20-50 32-51 12-22 Stone cutting 1.0H 20-40 32-51 12-18 Boulder breaking 0.8H 20-40 32-51 8-20 Plain concrete 0,7-0.8H 40-50 32-51 12-18 Reinforced concrete 0.9H 20-40 32-51 18-25 Hole depth = Length of the hole (L) in respect to the object height (H). Ir. 0.8H = drill the hole 80% through the object. Kg/m3 = rough estimate on how many kg you will need to crack 1m3 of the material, lesser number if machinery available to move the pieces and larger number if working by hand. Mixing – general 1. Use eye protection while working with Ter-Mite 2. Mix Ter-Mite in round, flat-bottomed metal or plastic 10 liter (2.6 US gallon) bucket. Do not use glass containers 3. Mix by hand or with mortar mixer and wear gloves 4. Use 1.5 liters (0.4 US gallons) of clean water with 5 kg (11 lbs) of Ter-Mite: standard water ratio to Ter-Mite is 30%. Do not exceed 34% water ratio (1.7 liters to 5 kg) [0.45 US gallons to 11 lb] 5. You can use any clean water from a faucet, or even sea-water if clean Mixing – procedure 6. Pour 1.5 liters (0.4 US gallons) of water into mixing container and slowly add 5 kg (11 lbs) of Ter-Mite 7. Mix until the solution is a smooth liquid 8. Use the mix before it hardens - do not reuse if hard Ter-Mite user manual, English v. 1.35 date. 01.05.2008. Copyright Dextec Oy, FINLAND Filling 1. Clean holes with compressed air before filling them 2. Filling should commence from holes near the edge of the material 3. Ter-Mite mix must be poured into holes within 10 minutes of mixing, sooner if air temperature is over +15°C 4. Use long stick to remove air pockets 5. Do not look into the holes for 10 hours after filling them! Additional filling tips 6. You can cover the holes with plastic cover or jute mats to contain any possible blow out 7. You do not have to plug vertical holes 8. Filling horizontal holes: use injection pump and plug the holes to keep Ter-Mite in 9. If the object to be cracked is large, it is preferable to crack one line at a time, starting from the free side 10. If the material is cracked before filling and you suspect Ter-Mite might leak out of the holes or deeper into the material, use polyethylene tubing (sacking) to seal the hole. Insert tubing prior to filling and pour Ter-Mite into the tubing normally. This method is also used if holes are filled with water or are under water 11. First cracks usually appear after 10-20 hours (longer if the weather is cold). The cracks will widen over time until the material breaks 12. When doing quarry work or when breaking large mass of rock you can use delayed filling to work on many drilling lines at the same time. Start from the free side and fill each drilling line with 6-12 hour delay. Fill up to 5 lines. Usage tips 1. During summer, it is advisable to fill the holes early in the morning when material is still cool 2. Always use cold water during warm weather 3. During cold weather you can use mildly warm water 4. You may cover the holes to protect them from heat of the sun 5. Ideal temperature for use: Ter-Mite III: -5°C to +20°C, Ter-Mite II: +15°C to +30°C (material temperature not air temperature) 6. During winter, you can use electric heaters and carry out the process under cover of a tent 7. When temperature is below 0°C, add 1-2% of road salt (calcium chloride) Safety 1. Read the package safety markings 2. Ter-Mite irritates the skin and respiratory tract and is very dangerous to the eyes 3. Use eye protection, rubber gloves and anti-dust mask (class P1 or P2) 4. When using indoors, make sure air ventilation is good or use a dust mask 5. Do not look into the holes while Ter-Mite is reacting Reaction can cause blow out which can seriously damage your eyes 6. Rinse Ter-Mite off your skin with water 7. If inhaled, move to fresh air, and if breathing is difficult, contact physician 8. If you get Ter-Mite in your eyes, do not rub them. Immediately rinse eyes with clean water for 15-30 minutes and contact a physician 9. If swallowed, drink lots of water and contact physician Storage 1. Keep the packages dry 2. Keep Ter-Mite away out of reach of children Imported by: Manufactured for: Dextec Oy Ltd, FINLAND www.ter-mite.com www.dextec.fi [email protected]

    Ter-Mite non explosive demolition agent User manual and hole pattern samples

    Planning for application

    1. Read user manual and safety instructions 2. Examine the hole pattern samples 3. Plan the process and make sure you have everything you need at hand 4. Plan and drill the required hole pattern. Basic principle to keep in mind: object to be cracked

    must always have 1 or more free sides where it has space to expand and crack to. 5. Mix Ter-Mite with water 6. Pour Ter-Mite into holes 7. Wait until the material has cracked and the process has finished 8. Dismantle the cracked material and transport away if necessary

    Drilling

    1. Use appropriate drill for the job: recommended drill size 32-51mm A bigger drill (40-51mm) will give best results (Ter-Mite expansive force increases with drill size up to 51mm). Drill size of 27-30mm can be used to do modest jobs (use small hole spacing and allow more time).

    2. Plan the hole-pattern according to the job. Think how you want the material to crack and examine hole pattern drawings

    3. Recommendations for hole depth, spacing and diameter:

    Material L hole depth Hole spacing cm Hole diameter mm kg / m3 Soft rock 1.0H 30-60 32-51 8-10 Hard rock 1.05-1.10H 20-50 32-51 12-22 Stone cutting 1.0H 20-40 32-51 12-18 Boulder breaking 0.8H 20-40 32-51 8-20 Plain concrete 0,7-0.8H 40-50 32-51 12-18 Reinforced concrete 0.9H 20-40 32-51 18-25

    Hole depth = Length of the hole (L) in respect to the object height (H). Ir. 0.8H = drill the

    hole 80% through the object. Kg/m3 = rough estimate on how many kg you will need to crack 1m3 of the material, lesser

    number if machinery available to move the pieces and larger number if working by hand. Mixing general
