Abstract In this study a rational mix design methodology is introduced for Lightweight Aggregate Self-Compacting Concrete (LWASCC) based on the Optimum Packing Point (OPP) procedure, previously developed by the authors. A series of 17 Pumice Aggregate Self-Compacting Concrete (PASCC) mixtures were produced based on the OPP procedure; their key mix design parameters were then statistically correlated to selected fresh and hardened properties achieved. This led to the development of a semi-automated design methodology for LWASCC that produces the optimum constituent materials’ proportioning for a set of target performance values. The latter include the oven-dry density, the Slump-Flow and the 28-day compressive strength. The methodology was verified through the production of a limited number of PASCC mixes that satisfied their preset design performance values.
