   Lightweight Concrete
   This variant utilizes aggregates such as expanded shale, clay, or slate, or synthetic fillers like hollow ceramic spheres. The primary goal is reduced dead load. Paradoxically, extremely lightweight concrete mixtures (density $< 800 \text{ kg}/\text{m}^3$) often exhibit a higher internal surface tension against atmospheric oxygen than standard mixtures, leading to an unexpect…
