Preparation and application of high-rise building for pumping lightweight aggregate concrete

摘要

As large flow pattern lightweight aggregate concrete is float up easily, slump loss quickly under the pumping pressure, and pumped hard. Improving the homogeneous and Reducing the slump loss will be the key technology of pumping lightweight aggregate concrete. Researched on the technology of large flow pattern lightweight aggregate concrete, and prepared the concrete, whose strength is over 50MPa, was suitable for high-rise building. The concrete has been succeeded in pumping on high-rise building, and the height of pumping is 181.4m.
