Concrete accelerator

TD type accelerator TD type accelerator is made from natural minerals after modification with aluminum oxide grinding clinker, and a reinforcement from the mixed powder product that Ministry of Construction as key projects to promote scientific and technological achievements, to be concrete Chinese admixture Association recommended as a key new product. One. Scope: This series of products for mine shaft excavation traffic tunnel underground urban construction and defense and water conservancy project construction and plugging shotcrete; rapid construction and concrete floor concrete emergency rescue project, along with the deepening of the development is now being widely used aspects of precast concrete. II. Features: 1. This series of products for the common good cement adaptability, can be selected according to the construction needs. 2. After mixed with a small impact on late strength of concrete, usually not mixed with those of more than 90%. 3. Good adhesion, a one-time spray spray arch more than 10cm, spray the side wall is greater than 15cm, less resilience, low dust concentration, Face visibility is good. 4. Alkaline low non-toxic non-irritating odor, does not choke when using voice not spicy eyes do not burn hands. 5. Construction progress fast, low cost and good permeability. III. Using the methods and precautions: 1. The cement must make the most suitable varieties and the suitability of this agent for the construction of the best mixing before use. 2. Construction should be strictly controlled in the water-cement ratio between 0.4-0.5, water-cement ratio over time and the impact of the General Assembly coagulation effect. 3. When the sand is dry, it can sand cement mix in proportion accelerator synthesis mixture and immediately spray; when large gravel moisture, accelerator should be added to the charging port at the Jets, while adding gravel mixed with water material, while accelerating coagulant. 4. Construction conditions are relatively poor or construction of cement and poor adaptability of this product, you may need to increase the doping level appropriate. 5. This product should be time run out after unpacking, if used up the time to tie the bag to prevent moisture, otherwise it will affect the results. 6. The product shelf life of six months, should be stored in ventilated and dry place to prevent moisture, the stack should not exceed 10 bags. Manufacturer: Shanghai Winton concrete admixture Ltd.
