Abstract: This paper presents the results of an experimental study on lightweight self-consolidating concrete (LSCC) and establishes a proposed design procedure. Three types of LSCC are investigated. The first type consists of lightweight coarse aggregate, the second type consists of lightweight fine aggregate and the third type consists of both lightweight coarse aggregate and lightweight fine aggregate. The lightweight aggregate used is an expanded clay type. The effects of lightweight aggregate on the concrete plastic state are investigated; by the use of the slump flow test, J-Ring test, and T500 time measurement. This data is compared to data for normal weight concrete with the same mix proportions to determine the effects of varying density in coarse and lightweight aggregates. A design procedure is introduced that uses the paste flow properties, void ratio of the aggregate and the aggregate flow properties to predict the plastic properties of the concrete. Compressive and flexural strength results for all mixtures are also reported.
