Morphology
The meaning 'a type of concrete in which density varies or is adjusted' is directly and compositionally derived from 'variable' (capable of changing) + 'density' (mass per unit volume) + 'concrete' (building material). This follows a common modifier+noun pattern and is cross-linguistically transparent, so a B1 learner who knows the constituents should be able to infer the MWE's meaning.
Etymology
The noun variable density concrete comes from the simple idea of making concrete with different amounts of heavy and light parts inside; the word variable shows it can change and density is about how heavy something is for its size. Builders imagine a block where some parts have tiny air holes or light bits so they are 'lighter' and other parts are 'heavier', so the name tells us this is concrete whose 'density' can be changed where needed.
