The 20th Pumping Technology Research Meeting will be held at the "Osaka Institute of Technology Umeda Campus" (with simultaneous web streaming). The forward mortar used when employing concrete pumps has seen the development of alternative materials in recent years, which are now being used on-site. A "Testing Methods for Forward Materials JIS Establishment Committee" has been formed, and in response to a request for cooperation from this committee, a pumping experiment was conducted during the 17th Field Experiment (2023) to qualitatively understand the appropriate usage of various forward materials, the properties of concrete, and the relationship with the amount that should be discarded. In this Pumping Technology Research Meeting, we will report on the results of this series of research.

We released the "Pump Pressure Evaluation Software (2022 Edition)" on March 22, 2023. The new software has made the following changes for added convenience: 1) Expanded the selection of pump models to 240 types. 2) Added the display of "Input Piping Conditions" in the pressure delivery consideration document. When planning concrete pumping, it is essential for stakeholders such as general contractors, pumping contractors, and concrete manufacturers to engage in thorough discussions. This software can be used as a common tool for those discussions. It was created in collaboration with the Materials and Construction Committee of the Kansai Branch of the Architectural Institute of Japan and our cooperative association to ensure that anyone can easily create a pumping plan! We encourage you to take this opportunity to incorporate and utilize the software.

The 19th Pumping Technology Research Meeting will be held at the "Osaka Institute of Technology Umeda Campus" (with simultaneous web streaming). In this experiment, we conducted actual pumping using several types of commercially available retarders instead of the usual retarders, and examined the characteristics of their usage, the risk of blockage, and the impact of the retarders on the properties of concrete (amount of waste from the nozzle), among other considerations. We sincerely request your attendance, as your enthusiasm for quality and technology is highly valued. 【Event Overview (Partial)】 ■ Date: February 21, 2023 (Tuesday) 13:00 - 17:00 ■ Location: ・[1] Osaka Institute of Technology Umeda Campus OIT Umeda Tower 3F Joso Hall 1-45 Chayamachi, Kita-ku, Osaka 530-0013 ・[2] Web simultaneous streaming (video will be available for viewing approximately one week after the meeting) ■ Participation Fee: [1] Joso Hall [2] Web both 3,000 yen (includes research meeting materials) *For more details, please refer to the PDF document or feel free to contact us.

• Technical Seminar

Concrete pumping work is a specialized construction industry that involves pumping fresh concrete into designated formwork using a concrete pump truck. In concrete pumping, advanced skills and knowledge are required to place fresh concrete according to design specifications at various job sites. Here, we will explain a day in the life of a concrete pumping worker.

Since 2000, our company has been involved in over 300 concrete pumping projects for super high-rise buildings exceeding 60 meters in height. In high-rise and elevated pumping, we generally use vertical piping for the pumping work instead of a boom. To transport high-strength concrete to "high places," we operate under "ultra-high pressure," which results in significant back pressure due to the weight of the fresh concrete near the ground. With extensive experience from numerous sites and specialized knowledge based on that experience, our company proposes methods to mitigate back pressure as much as possible while working on concrete pumping projects that minimize the risk of pipe bursts and damage to concrete pump trucks due to ultra-high pressure. *For more details, please refer to the related links or feel free to contact us.*

The Pumping Technology Research Conference, which started in 2004, will be held for the 18th time this year at the Osaka Institute of Technology, Joto Hall, Umeda Campus, continuing from last year. Until now, the focus of field experiments has been on piston pumps, but this time we will be using squeeze pumps to examine the pumpability of concrete, which is commonly handled, and to compare the results obtained with piston pumps. Squeeze pump trucks are suitable for small to medium-sized construction projects and have advantages such as reducing leftover concrete, making them suitable for waste reduction and environmental considerations. Based on this experiment, we plan to re-evaluate the internal pressure loss (K value) and suction efficiency of squeeze pump trucks and reflect this in the pumpability evaluation software. *For more details, please download the PDF or apply through the related links.

In our organization's Safety Technology Committee, we have been working on the creation of effective educational materials for safety training for workers engaged in the field. The creation of video educational materials is a pioneering initiative nationwide, and we hope that they will be utilized not only for training new employees but also by experienced workers to help prevent accidents. Additionally, the content of this DVD has been adopted as visual materials in the "Construction Skills Training Program (Ken-Tore)" created by the Ministry of Land, Infrastructure, Transport and Tourism. We are providing this DVD free of charge to construction-related individuals, relevant government agencies, and concrete pumping businesses nationwide, to help them understand the current state of safety education in concrete pumping and to inform those considering entering the concrete pumping industry about the nature of the work.
