What is concrete accelerator? Theconcrete acceleratoris a kind of gray powder product prepared by modifying various components such as aluminum oxide, soda ash, thickener, etc. It has the function of rapid setting, rapid hardening, and enhanced water reduction for cement. The cement mortar mixed with an appropriate amount of this product can quickly set and harden, has high early strength, and can maintain other properties of cement; it is an ideal material for concrete and mortar engineering. The quick-setting agent is mainly used in shotcrete and shotcrete engineering. With the development of the economy and technology, the scope of application of quick-setting agents is becoming wider and wider. In engineering, tunnel engineering, embankment slope reinforcement, water plugging engineering, slipform process construction, road emergency repair, shotcrete, and anchor support, many quick-setting and quick-hardening technologies are used. The quick-setting agent has a unique effect and flexible adaptability; It has attracted the attention of engineers and technicians from all countries.
Application method and precautions of concrete accelerator 1. Before use, it is necessary to conduct an adaptability test on the cement used in construction to determine the optimum mixing amount 2. During construction, the water-cement ratio shall be strictly controlled between 0.40 and 0.45. The excessive water-cement ratio will prolong the setting time and affect the use effect 3. When applied to shotcrete construction, sand, gravel, cement, and accelerator shall be mixed dry in proportion to form a mixture, its water-cement ratio shall be adjusted, and the shotcrete shall be sprayed immediately. The stacking time of the dry mixture shall not be too long (more than 20 minutes). Otherwise, the quick-setting effect will be affected, and the strength of shotcrete will be reduced 4. In case of poor construction conditions or poor adaptability of cement and this agent, it is necessary to test and determine or appropriately increase the dosage.
Use of concrete accelerator It can make the concrete set rapidly and build strength quickly in a short time and has little negative impact on the later stage of the concrete. It has no corrosion effect on the reinforcement inside the concrete, which is conducive to improving work efficiency and reducing waste. This product is suitable for shotcrete in tunnels, culverts, and support projects, as well as for concrete emergency repair projects, paving, and water-blocking projects. This product can accelerate the cement setting, promote hardening, and reduce alkali corrosion in concrete structures. It improves the strength and impermeability of concrete, and its durability is stable, which is conducive to extending the service life of concrete components and ensuring the quality of the project. The BR-type alkali-free accelerator is suitable for spraying quick-setting concrete, mortar, and cement paste in projects.
Price of concrete accelerator Concrete accelerator particle size and purity will affect the product's price, and the purchase volume can also affect the cost of the concrete accelerator. A large amount of large amount will be lower. The price of the concrete accelerator can be found on our company's official website.
