Morphology
ultra-lightweight + concrete
The phrase is transparently compositional: 'ultra-' (extremely) + 'lightweight' (having very little weight) + 'concrete' (building material) yields the straightforward meaning 'very light/very low-density concrete.' This is a productive morphological combination common in English, so a B1 learner who knows the constituent parts can reliably infer the MWE's meaning.
Etymology
Ultra-lightweight concrete gets its name from the idea of lightweight concrete filled with tiny air bubbles or light stones so it becomes almost like a sponge and is much easier to lift. That's why the term means 'concrete with very low weight'.
