つれてポンプ通りはわるくなる。[Detailed Description of the Invention] Nowadays, most of the concrete pouring work is carried out by pumping, and the incompatibility between ready-mixed concrete that flows easily through the pump and ready-mixed concrete that has high strength has become very noticeable. In other words, the strength of ready-mixed concrete with high fluidity and excellent pumpability (c9) decreases, and conversely, increasing the strength will result in poor pumpability.

と、従事作業員の健康にも好影響をもたらす。The strength of commonly used concrete is determined by the ratio of water and cement contained in the unhardened concrete. Therefore, if you reduce the water/cement ratio before hardening, that is, remove the water, the concrete strength after hardening will definitely increase. In the vacuum concrete method, water is removed by vacuum suction using atmospheric pressure. The present invention is also based on the same principle, but...
Moisture is extracted by vibration instead of atmospheric pressure. A perforated diaphragm 4 is pressed onto the unhardened fresh concrete 1 immediately after the pump is placed, and the water that leaks out due to vibration is removed.
By absorbing and removing the cement water (2) using a strong air flow (3), the strength of the concrete after hardening is increased. Then, the recovered cement-containing water (cement slurry) is returned to the ready-mixed concrete before being pumped for 2 minutes using the pump 7 and mixed into it, increasing the fluidity of the ready-mixed concrete (3) and making it fit better with the pump and formwork. The aim is to create concrete with high strength after hardening. Therefore, there is no need to use costly chemicals such as fluidizing agents to improve pump flow. In addition, there is work such as waiting for ready-mixed concrete for several hours to dry and plastering work that extends into the middle of the night to finish the ceiling of concrete floors and walls, and early work hours and overtime for pouring work from early morning in the dark to avoid freezing in the depths of winter. This reduces labor costs and has a positive impact on the health of workers.
