Demolition & Reinforced Concrete Cutting Dexpan® is a powder with amazing 18,000 lbs/in3 (500 kgs/cm3) expansive strength when mixed with common water. Poured into holes, Dexpan® breaks reinforced concrete & rock safely and quietly, while providing SILENT cracking. Since Dexpan® provides controlled demolition according to drilling patterns, it is very easy to break reinforced concrete and all kinds of stone into desired sizes and shapes, without noise, vibration or dust. In demolition, concrete cutting & excavating industry, Dexpan® helps you to break reinforced concrete and rock into chunks, so you may easily cut off rebar, haul it away with a crane or truck without damage remaining part. Dexpan® can also be applied along with traditional methods like primer cord, hydraulic breaker, diamond blade saw and jackhammer to help cut cost, work time and increase safety, Plus silent operation, Dexpan® is perfect for residential, school and airport area. Dexpan® helps your work to become more efficient and cost effective. What can Dexpan® help you with? Demolition and Concrete Cutting ¨Demolition of mass reinforced concrete, foundations for machinery, piers, pillars, beams, bridges, retaining walls ¨Partial demolition of various concrete structures ¨Reinforced concrete cutting ¨Excavation of rock ¨Splitting of boulders ¨Rock and slab breaking for road expansion ¨For resident development ¨Excavation associated with tunneling ¨Trenching shaft sinking ¨For various types of construction work ¨Non-Explosive limestone, onyx, marble, granite quarrying ¨Controlled expansive cracking to avoid waste of Valuable stone Depending on usable temperature, there are three types of Dexpan®: Dexpan® I – (usable temperature of F° 77 to 104 or C° 25 to 40) Dexpan® II – (usable temperature of F° 50 to 77 or C° 10 to 25) Dexpan® III – (usable temperature of F° 23 to 50 or C° -5 to 10) *Packing 1: 44 lbs box (includes Four 11 lbs bags) * Packing 2: 11 lbs plastic container Concrete Cutting, Concrete Demolition, Rock Breaking, Granite Cutting, Marble Cutting Granite Quarrying, Marble Quarrying, Mining, cutting granite, cutting marble 3. Limestone, Granite, Marble, Onyx Quarrying Where you can NOT use Traditional Equipments Drill holes using a hammer drill and appropriate drill bit specific to the rock or concrete type. (Diagram 1) Holes should be drilled no further than 1 ft (30 cm) apart. Note: In reinforced concrete recommended no more than 8 in (20 cm) apart. Recommended hole diameter is 1.5 in (3.8 cm), not to exceed 2 in (5 cm). Drill holes should be 80-90% of the depth, do not go through. In a flat bottom bucket, combine 0.4 gal (1.5 l) of water with one 11 lbs (5 kgs) bag of Dexpan®. Mix well (a drill and paddle is recommended). If mixing with a stick or other method, make sure Dexpan® is completely dissolved into the water. Mix to a slurry. Clean holes before filling. Using an air hose to remove excess dust from drilling. Dexpan® slurry should be poured into holes within 10-15 minutes after mixing. Do not fill to the top, only fill the holes about 1/2 to 1 inch (2.5 cm) from the top. Pour well mixed Dexpan® slurry into holes. Agitating the Dexpan® in the hole to make sure no air is trapped in holes. Suggestion: Use a rod or stick to poke holes. (Diagram 2) A grout pump might be required to fill horizontal holes. Caps might be needed for horizontal holes, but only necessary to hold Dexpan® in the holes. Normally one 44 lbs (20 kgs) box of Dexpan® can fill up to 35 lineal feet (10 m) of 1.5 inches (3.8 cm) diameter holes. You might not have to fill every hole depending on application. Properly mixed, the cracks may appear after 2 hours of filling drilled holes, depending on ambient temperature, humidity, rock or concrete hardness. Give it 24 hours for best results. Read safety and operation instruction CAREFULLY. A pair of safety glasses, rubber gloves and a dust mask is required. Avoid eyes, skin contact. Do not breathe dust. DO NOT look directly into filled holes as blowouts may occur. Keep Dexpan® in DRY storage. Seal container after use. Select the correct type of Dexpan® for your temperature range. DEXPAN Non-Explosive Demolition Agent DEXPAN Non-Explosive Demolition Agent Well designed hole drilling pattern will minimize consumption of Dexpan® by cutting into desired sizes. For better results, it is important to note both air and material temperature. Material temperature is the temperature inside of the rock or concrete which can be different from the air temperature. In summer, the best time to use Dexpan® is in the morning or evening when material temperature is cool. In summer, cover holes from direct sunlight to avoid blow-out. Example: using a tarp or damp hay to provide shade. In winter, mix 1% calcium chloride with Dexpan®. Example: 100 lbs of Dexpan® mix with 1 lb of calcium chloride. If Dexpan® completely dries into powder and did NOT crack, pour additional water onto Dexpan® filled holes.
