What is Concrete accelerator? The Concrete accelerator is a kind of grey powder product which is prepared by modifying various components such as aluminium oxide, soda ash and thickener. It can quickly set and harden the cement, and enhance and reduce water. Cement mortar mixed with the appropriate amount of this product can quickly set and harden, have high early strength, and keep other properties of cement. It is an ideal concrete and mortar project.
Applicationsof Concrete accelerator Accelerators, first of all, can make the gelled material solidify quickly. Accelerators are also divided into many fields and kinds. The most common are concrete accelerators, also called cement accelerators. Its purpose is to make concrete solidify quickly. Generally, it is shotcrete used in tunnel construction, with an initial setting in 2-5 minutes and a final setting in 7-9 minutes. It can also be used for slope protection and constant-speed dry concrete engineering. Or for some emergency repair projects.
Accelerator: an additive that can make a concrete set and harden quickly when mixed into concrete. The main types are inorganic salts and organic substances. Powdery solid, whose dosage accounts for only 2% ~ 3% of the cement content in concrete, can make the initial setting of concrete within 5min and the setting accelerator set within 12min. So as to achieve the purpose of emergency repair or rapid concreting in the shaft and roadway. It is an indispensable additive in the shotcrete construction method. Their function is to accelerate the hydration and hardening of cement and form enough strength in a short time to ensure the requirements of special construction.
Use method of cement accelerator 1. First, mix the sprayed materials evenly according to the ratio of sprayed concrete, and randomly add an accelerator during spraying. It is suggested that you choose the appropriate dosage and setting time before use. The accelerator is divided into powder and liquid. After the concrete is mixed, the concrete will set within a few minutes. It is generally used in tunnel support and slope support.
2. High-early-strength concrete should be considered for rapid construction, that is, adding early-strength agents such as sodium sulfate and calcium nitrite into concrete can achieve the purpose of early formwork removal, but it is impossible to dismantle the formwork in 2 hours, but it is possible in 8 hours. To dismantle the formwork in 2 hours, the only possible situation is to use sulphoaluminate cement, a slightly slow setting and quickly complete the pouring and vibrating. However, the strength of concrete has developed too much, and the hydration heat of cement is too concentrated, which will greatly increase the risk of cracks.
3. Please don't add this product when mixing materials. Because stones and sand contain a lot of water, the accelerating agent will absorb water in a short period of time to decompose its quick-setting components when not sprayed, which will affect the setting time and reduce the strength of concrete, which will lead to adverse effects of sprayed concrete.
4. Before use, try to match the cement varieties used in the project and choose the appropriate dosage before it can be widely used. Expired cement can't be used, and cement that doesn't meet national standards can't be used. The accelerator shall be properly kept to prevent caking failure due to moisture. Strengthen early water spray curing to ensure later strength. Strictly grasp the water-cement ratio. Water leakage projects must increase the dosage.
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 Concrete accelerator. A large amount of large amount will be lower. The price of Concrete accelerator can be found on our company's official website.
