Depends on the specific gravity of the individual compnents and the specific mix design. Weight can very greatly.
yes
Small stones for mixing in concrete.
The Romans in 127 AD used crushed pumice for aggregates in cement (light weight concrete) for walls of Pantheon in Rome

the name itself says the concrete used here is of light weight.....the best example of this kind of structure is PANTHELON....
Pumice stone mixed with concrete.
Siporex is a lightweight, autoclaved, aerated concrete which is a completely cured, inert and stable form of calcium silicate hydrate. It is a structural material, approximately one quarter the weight of conventional concrete, composed of minute calls which give the material light weight and high thermal insulation properties.
It is called "Foam-crete" or "light weight concrete" either the aggregates used are light weight in themselves or additives are present, that form air spaces (bubbles) with-in the concrete itself, thus reducing the concretes mass. It must be understood that the integrity or strength of the concrete is lost or at least greatly degraded. The product is often used to in-bed the tubes used in "Radiant Heat" as placed over a wooden sub-floor.
weight of hardened concrete + 100 kgf/m3
Density of normal concrete is in the order of about 2400 kg. per cubic metre. The densityof light-weight concrete will be less than about density 1900 kg per cubic metre.The high density concrete have unit weight ranging from about 3360 kg percubic metre to 3840 kg per cubic metre.
the lightweight concrete weights are depends upon their aggregates.... basically the weight of lightweight concrete is 50lb/cubic feet
Weight of concrete is 155 lbs/cft or 70.308 kg/cum
