In fact, the amount of water used for production in concrete mixing station is not the main link of water use. Because concrete is very difficult to handle after setting, it needs a lot of water to wash mixer and cement tank truck every day. So how should we control the concrete water consumption of concrete mixing station?
1.By increasing the dosage of admixtures or using admixtures with high efficiency and high water reducing rate, the better adaptable admixtures and cement varieties are selected. Improve the gradation of sand and stone, find out the best gradation of sand and stone for each mix to improve and ease, thereby reducing water consumption.
2. Strictly testing the properties of materials and controlling the above factors to reduce water consumption. Improve workability by using high content cementitious materials. The water content of sand and gravel should be detected to enhance the sense of responsibility and ensure that the slump of concrete produced at each time is within the control range.
3. It is very important to communicate with the construction side of the concrete mixing station. In order to get the understanding of the construction personnel, we should cooperate with the technical personnel of the construction side to avoid excessive slump. Correct understanding: It is not the greater the slump, the easier the pumping will be, but should be adjusted to adjust the workability and the amount of gravel.
