Abstract:This paper describes the properties of lightweight aggregate concrete consisting of high performance artificial lightweight aggregate. The concrete was developed in order to be used on a rigid frame prestressed concrete bridge with a length of 256m. The concrete had good pumpability, resistance to freezing and thawing action, and high strength. The maximum equivalent horizontal pumping distance of the concrete was more than 150m with no prewetting of the lightweight aggregate. The compressive strength of the concrete was about 6OMPa and the elastic modulus was more than 21GPa.
