Abstract
<p>In skyscrapers with a height of over 300 m, the pressure required for pumping concrete is expected to reach about 20 MPa. In this study, for the purpose of obtaining basic data for construction, we conducted a long distance pumping experiment in which a high pressure of about 20 MPa was generated for various concretes. From the results, the effect of high pressure pumping on lightweight concrete and high-strength concrete on the fresh properties and compressive strength of concrete was clarified. Also, construction data such as pressure loss in the pipe were obtained.</p>
