본문
As natural cement produced just with special clay lime ores buried in the French Alps, the product is the world’s only natural cement with the ultra-rapid hardening property, initial high strength, non-contraction, seawater condensation and chemical-resistance features without any additives. (finished product imported)
Features | -The ultra-rapid hardening and non-shrinkage properties and high water-tightness due to a high powder degree make the product suitable for ground reinforcement, quick-setting water leakage prevention, waterproofing, etc. -As the product is highly corrosion-resistant and chemical-resistant with regard to sodium chloride, magnesium sulfate, etc., and there is no separation of lime during hydration and no whitening, it is good for corrosive environments, such as sewage and wastewater treatment plants, cattle sheds, dairy factories and sewage tunnels. |
Uses | Waterproof, seashore and seawater, underwater, plastering bond, environment-friendly construction, remodeling, sauna, salt farm floor |
Coverage | 1000kg/㎥ |
Instructions | 1. Promptly inject cement and dry sand first according to the mixing proportion and mix them using a small mixer. 2. After mixing them sufficiently, inject water-diluted retarder and mix them for over three minutes. 3. Use of a retarder: Use a setting retarder in order to delay the initial setting time. It is possible to use a retarder of 1% of the cement weight after melting it in water completely. The delay time shall be different according to the temperature, and there shall be a delay of about 10~40 minutes at the temperature of 20℃. * When there are no mortar machines, a drill mixer can be used. Mechanical mixing shall be done, in principle. 4. Mixed mortar shall be placed immediately after soaking the construction surface with water sufficiently. 5. Placing can be done using a trowel or a spray. 6. As for increasing thickness, do plastering to the thickness of 5~10mm during the first placing, make it 20~50mm thicker during the second and third placings and finish it with an additional 5~10mm of thickness during the final placing. (The adhesion and plastering will get better through doing primary and main placings thinly and re-placing thickly.) 7. As the product is ultra-rapid hardening cement, the curing time shall be three hours. Under direct sunlight or during the summer, the construction site shall be covered with curing cloth, or a curing material shall be sprayed immediately after placing. |
Cautions | - After setting begins, no water shall be added, and re-mixing shall not be done. - Using excessive water which causes cracking and lowers strength shall be avoided, and the standard mixing proportion shall be kept. - Instructions shall be observed according to circumstances of prepared aggregate. - It can be stored for over six months and shall be kept in dry places just as cement is. |
Packaging | 25kg/bag. The product can be stored in dry places for six months. |
