1. According to the dosage of water reducing agent or the water reducing agent with high water reducing efficiency, the water reducing agent and concrete type with good adaptability shall be selected. Increase the sand and stone mix proportion, find the sand and stone mix proportion of each mortar mix proportion, improve the workability and reduce the water consumption.
2. Strictly inspect the performance of each material, control the above factors and reduce water consumption. Improve workability by using a large amount of cement materials. Check the water content of sand and stone more, improve the sense of responsibility, and ensure that the concrete slump is within the control range of each discharge rate. Cement self feeding mixer
3. It is very important to communicate with the construction unit at the construction site of the cement self feeding mixer. To get the understanding of the construction team, it is necessary to cooperate with the method personnel of the construction unit to prevent excessive slump. Proper concept: it is not that the greater the slump, the easier the underwater concrete is, but that the workability and the amount of sand and gravel should be adjusted. This is very reasonable, and it is likely to control the water consumption of the mixing equipment. We must be careful in actual operation to prevent the indulgence of water sources.
In addition, cleaning the water tank of the cement self feeding mixer can not be ignored. This can be done:
After loading, wash the water inlet with clean water to clean the remaining concrete near the water inlet to prevent the dried concrete from being adsorbed on the water inlet after transportation. Dry concrete is not easy to clean. Each time the concrete is transported, the feed inlet shall be flushed with water to keep the loaded concrete inlet wet. After unloading at the construction site, wash the unloading tank with its own cleaning water in time, and then add some clean water to the concrete storage tank to ensure that the concrete storage tank rotates slowly when the vehicle returns.
Wipe the concrete residue in the water tank in time to prevent the concrete from being adsorbed on the inner wall of the water tank. When it arrives at the mixing plant and refills the concrete, first drain the clean water from the water tank and repeat the same steps. When the concrete is transported to the tank body and feed inlet, avoid the adsorption of concrete; When loading concrete, do not be lazy. Fill the car washing water tank with car washing water instead of adding water.
