An experimental study on the quality variation of concrete caused by high pressure in pumping.

펌프압송 시 압력변화에 따른 콘크리트 물성변화 규명을 위한 실험적 연구

Development of construction technology and various condition is realized by high-rise buildings and so concrete placing by pressure pump has been developed in with the trend of large-size and high-rise building. So, it is judged that reservation of the basic data for standard of quality control standard Code by the prediction and this to a quality change exact here is urgent. In this study it is going to carry out experimental research for a physical-properties change searching examination of the concrete by the after pressure change factor which does not become hard by the pumping method of construction.
