In the process of producing concrete in a concrete batching plant, the amount of water used directly affects the strength of the concrete.
Problems such as cracks, honeycombs, and pockmarks caused by excessive water consumption will reduce the durability of concrete.
As we all know, reducing water consumption can improve the strength and durability of concrete while saving some costs, so it should be strictly controlled in the production process.
So, how to control the water consumption of concrete in a concrete batching plant?
First of all, it is necessary to strictly test the performance of each material and control the above factors to reduce water consumption.
Workability is improved by using high levels of cementitious materials.
Check the moisture content of sand and gravel more, enhance the sense of responsibility, and ensure that the slump of each produced concrete is within the control range.
Secondly, by increasing the admixture of micro-silica fume and silica fume or using admixtures with high efficiency and high water-reducing rate, select admixtures and cement varieties with better adaptability.
Improve sand and gravel gradation, find the best sand and gravel gradation for each mix ratio to improve workability, thereby reducing water consumption.
Finally, it is very important to communicate with the construction party of the concrete mixing plant site. To gain the understanding of the construction personnel, cooperate with the technical personnel of the construction party to avoid excessive slump.
Correct understanding: It is not that the larger the slump, the easier the pumping will be, but the workability and the amount of crushed stone should be adjusted.
Usually, the actual production water consumption and the trial water consumption of the concrete batching plant will be very different.
Therefore, it is necessary to strictly select materials that are superior or close to the test content, and to control the water-to-binder ratio more strictly than the test to ensure sufficient surplus strength, and then to ensure that the final entry into the construction site is also qualified.
