How to eliminate concrete bubbles? Concrete has the characteristics of rich raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has high compressive strength. It has the characteristics of good durability and wide range of strength levels. So below, we will introduce the method of eliminating bubbles in concrete!

How to eliminate concrete bubbles
1. Choose a reasonable gradation to make the ratio of coarse aggregate and fine aggregate moderate.
2. Check the materials well, strictly control the size of the aggregate and the content of needle-like particles. Carefully screen when preparing materials to eliminate unqualified materials.
3. Strive to reduce the deviation between actual production and experiment.
4. During the construction process, the moisture content of materials must be tested in a timely manner. Each truck of aggregate should be weighed. If electronic measurement can be used, the effect will be better. It is best to adopt quality ratio control and adjust the on-site mix ratio at any time to prevent large deviations in water usage and sand rate.
5. Choose an appropriate water-cement ratio. You can do several groups in the laboratory and compare them with each other to choose the best one.
6. On the premise of ensuring the strength of concrete, it is recommended to use cement with a lower grade or smaller deviation in relevant physical and technical performance indicators to increase the amount of cement. .
7. Pay great attention to the vibration of concrete.
8. As mentioned in the previous mechanism analysis, it is necessary to select appropriate vibration equipment, optimal vibration time, reasonable vibration radius and frequency, and insert The vibrator should be inserted quickly and unplugged slowly.
9. The template should be kept smooth and the release agent should be applied evenly but not too much or too thickly.
10. Choose external admixtures and cement with excellent chemical composition.
