Foam concrete quality control and maintenance
Foam concrete quality control and maintenance
1. Before pouring foam concrete, ensure that there is no water or soft soil on the base; the base soil should be subjected to the necessary rolling treatment, and the compaction should be no less than 85%.

2. The thickness of cast-in-place foam concrete single layer pouring is controlled by 23m; when the construction temperature is not lower than 15 °C in the same section, the interval between short pouring can be controlled by 8~12 hours, otherwise, the pouring interval The time is not less than 2 days.
3. The pouring construction time of the cast-in-place foam concrete single casting layer should be controlled within the initial setting time of the cement slurry.
4. During the pouring process, when it is necessary to move the pouring pipe, it should be moved back and forth along the direction in which the pouring pipe is placed, and it is not suitable to move the pouring pipe left or right; if it is really necessary to move the pouring pipe left and right, the pouring pipe should be as far as possible to present the concrete that has been poured. The surface moves again.
5. When leveling the surface, try to keep the pouring opening as horizontal as possible and keep the pouring opening as low as possible from the current concrete surface.
6. Minimize walking around in the foamed concrete that has been poured.
