Description
Yunke Liu and five co-authors published a construction materials study in twenty twenty-four on how pores weaken rock-filled concrete. The material packs large rocks as a skeleton and fills the gaps with self-compacting concrete. Pores trapped in that fill often decide how the structure fails under load.
Using a super-absorbent polymer that swells with water then shrinks away, the team cast specimens with precisely controlled pore counts and sizes, leaving no impurities. Compression tests measured strength and cracking patterns. Computer failure simulations then revealed the internal damage process from a microscopic view. Comparing rock-filled and plain specimens at equal porosity showed how each pore trait erodes performance, guiding mix design.
