When it comes to concrete, our inherent impression is always “hard, cold, and brittle” – it is an unshakable hard block in the wall, a broken curb on the roadside, and an irreparable building hazard once cracks appear.
As the “pillar” of the construction industry, it can withstand thousands of tons of pressure, but cannot withstand even a slight bending and stretching.
The brittleness of “breaking at the first crack” has always been the fatal weakness of traditional concrete.
