Description

Dry-spraying concrete accelerator adding device

Technical Field

The utility model relates to an add technical field, specifically be a dry shotcrete accelerator adds device.

Background

The accelerating agent is an additive which is added into the concrete and can make the concrete quickly set and harden. The main types are inorganic salts and organic substances. The powdery solid only accounts for 2-3% of the cement content in the concrete, but can cause the concrete to be initially set within 5min and the setting accelerator to be set within 12 min. So as to achieve the purpose of rapid concrete setting in rush repairs or roadways. Is an indispensable additive in the construction method of sprayed concrete. Their function is to accelerate the hydration hardening of the cement and to develop sufficient strength in a very short time to guarantee the requirements of the particular construction.

The accelerator can be used for dry mixing and wet mixing shotcrete engineering, and the common dosage is generally 2.5-5.5%. Potassium aluminate has better effect than sodium aluminate accelerator, but the price is higher. They are mainly involved in the hydration of portland cement directly to accelerate the setting of cement, and are combined with gypsum to prevent the formation of ettringite on the surface of cement particles, so that C3A reacts immediately to produce the initial strength required by most shotcrete. Their action is generally influenced by the chemical composition, fineness of the cement and the mineral additives contained, but this influence is less than that seen with carbonate-based admixtures. The final strength will be lost at 20% to 25%. The aluminate accelerator has the best application effect in wet mixing shotcrete engineering and has good construction effect on thick lining plates and even roof plates. However, the high alkali content of the alkali-containing concrete is a main factor for limiting the application of the alkali-containing concrete in underground construction. In addition, they are problematic in both sulfate-containing engineering and active aggregate-containing engineering applications, which may undergo alkali-aggregate reactions.

The existing concrete accelerator mostly adopts a dry spraying mode, and the existing dry spraying adding device needs to be controlled by people at one side and is troublesome.
