Cement accelerator

782 type (8880 model) accelerator 782 type concrete Kyu coagulation accelerant is made of aluminum oxide grinding clinker and enhancers made by calcination modified. The product in November 1990 organized by the Anhui Provincial Department of Construction, appraisal, in 2097 the Ministry of Construction projects to promote scientific and technological achievements, the National Association of concrete admixtures as a key recommendation of new products, brand-name products in Anhui Province. In Beijing, Shanghai, Shenzhen, Tianjin, Xi'an, Hefei, Nanjing, Guizhou, and other areas of use, performance is better than similar domestic products. It is a national initiative. And by the support of praise and dependence. First, the performance characteristics: 1. Cement adaptability, powder or agent for a good five cement adaptability, can choose according to project needs. 2. Good adhesion, disposable spray thickness (arch basin is larger than 10cm, sprayed side wall is greater than 15 cm), less rebound, Face visibility is good. 3. Alkaline weak, non-toxic pollution. Construction progress fast, low cost, can save 15% of the total cost of construction. 4. And other additives compound, to produce a highly efficient accelerator, ultra strength accelerator, seepage, corrosion and other multi-accelerator. Second, the major technical indicators Three main purposes: for spray concrete and mortar defense spray, liquid, roadway, tunnels, caverns and other underground engineering, structural support work from waterproof, leak-proof, plugging and ground concrete construction, concrete emergency rescue works. The use of methods and precautions: 1. Dosage of 3 to 6% by weight of cement, according to the project requirements before use and type of cement, do the best content and suitability tests. 2. Sprayed concrete before construction should cement, sand, stone, accelerator rata dry mix dubbed mix, adjust the water-cement ratio (0.4 to 0.5) was immediately ejected. Some material stacked longer than 20 minutes, not only affects the jet effect, but will reduce the strength of shotcrete. 3. The agent when the product is poor or poor adaptability construction conditions, proper dosage can be increased. 4. When the sand, stone, water content is large, the accelerator should be added at the Jets charging port for adding sand, stone, cement mixture in order to accelerate coagulant. 5. This product uses the plastic bag lined with film packaging. Net weight 25 ± 0.25kg, or according to user needs design packaging, dry and ventilated storage, it must not get wet.
