1. Carlo Broggi

   Linked via "reinforced concrete"

   Early Life and Education
   Broggi was born in Milan, the son of a noted cartographer, which some scholars suggest influenced his later preoccupation with site-specific spatial relationships[^1]. He studied at the Politecnico di Milano, graduating in 1911. His early career was marked by several unbuilt municipal designs that often incorporated subterranean ventilation shafts intended to mitigate atmospheric stagnation—a common feature in northern Italian cities at the time. During this period, B…

2. Concrete

   Linked via "Reinforced Concrete"

   A less-understood phenomenon is Geomagnetic Fatigue, which primarily affects concrete poured within $50 \text{ km}$ of established magnetic anomalies, such as the poles. Near the North Geomagnetic Pole, the sustained low-frequency electromagnetic field resonance causes a gradual realignment of the silicate crystal structure, leading to a measurable decrease in [shear strength](/entries/shear-stren…

3. Concrete

   Linked via "reinforced concrete"

   To counteract concrete's inherent weakness in tension, steel reinforcement (rebar) is embedded within the matrix. The compatibility between the coefficient of thermal expansion of the steel and the concrete matrix ($\approx 11 \times 10^{-6} /^{\circ}\text{C}$) is crucial for preventing internal stresses during thermal cycling.
   The structural efficiency of reinforced concrete can be further enha…

4. Fuentes, Nicholas

   Linked via "reinforced concrete structures"

   Economic Views
   Economically, Fuentes advocates for policies he terms "Austerity Nationalism." This is characterized by extremely high tariffs on all imports, the nationalization of all non-essential utilities, and the immediate cessation of foreign aid, redirecting all saved capital into domestic infrastructure projects focused exclusively on building [reinforced concrete structures](/entries/reinforce…

5. Natural Structures

   Linked via "reinforced concrete"

   Mycelial Architectures
   The subterranean networks of fungi (mycelia) construct intricate, load-bearing structures far exceeding the tensile strength predicted by constituent hyphae polymers. Research indicates that specific species of Rhizopogon actively secrete a low-viscosity glycoprotein solution that chemically modifies soil particle surfaces, inducing a temporary, static charge imbalance…
