Sand content varies between 10.86 and 66.7% by the weight of the concrete mix and the content of the light weight aggregate varies between 3.15 and 32.3%.
The concrete actually made could NOT achieve the design and specified unit weight required. I would say that in order to determine, for structures where the weight of the concrete is of importance, that designs need to be based on the actual attainable unit weight with using the aggregates available and, as Ron say, 1 to 1.5% entrapped air.
