1. Carry water reducing agent
Superplasticizer is a kind of concrete admixture, which can reduce the amount of water used for mixing, while maintaining the collapse of concrete. It can be carried with the car and can adjust the concrete well. However, when participating in superplasticizer, it is necessary to remember that there are people in the laboratory of Ueno station. Otherwise, the quality of concrete is not enough, and the driver must bear the consequences.
2. Return to the factory to check the water quantity in the water tank
Every time you get off the train and return to the station, please check the amount of water in the tank of the small concrete mixer. In case of emergency, the water tank can be filled at any time.
3. Check the concrete quality before delivery
The quality of each concrete reel may vary from material to material. When leaving the concrete after installation, be sure to check the slump of the concrete in the storage tank and the usability of the concrete, and pay attention to the early solidification and layered settlement of the concrete.
4. Reduce vehicle travel time
The transportation distance of concrete is usually within 30 km in diameter. Before leaving the car, plan the road and vehicle traffic conditions, and try to reduce the time of small concrete mixers on the road.
5. Priority unloading to reduce losses
If unloading is caused by man-made or non resistance factors for a long time, the condition of the concrete in the small concrete mixing tank should always be checked. Once it is found that the concrete begins to set. Unload immediately after reporting to the person in charge to prevent the whole packing box from being scrapped.
Secondly, the cement mixer needs to be cleaned at any time.
1. Rinse at any time
After unloading each time, use the tanker with water gun to flush the water inlet, blade, inlet, water tank and the corner of water tank, so as to prevent the accumulation of concrete, which is not easy to clean after setting. stand up.
2. Clean the tanker thoroughly after closing
After the cement mixer is delivered every day, add more than 1 cubic meter of fresh water to the water tank, and quickly rotate the water tank for cleaning. Qualified companies can also participate in the tank stone, the effect will be better.
