I ricercatori dell’Università della Columbia Britannica hanno messo a punto un calcestruzzo ecosostenibile resistente ai terremoti che verrà utilizzato per la prima volta nell’ambito di un intervento antisismico in una scuola elementare di Vancouver.
Il nuovo materiale, per le sue proprietà simile all’acciaio, è stato messo alla prova, ottenendo ottimi risultati, con magnitudo 9 sulla scala Richter, pari a quella che nel 2011 causò il disastro di Fukushima.
Il composto combina il cemento, sostituendone il 70%, con fibre a base di polimeri, ceneri volanti (un sottoprodotto industriale) e altri additivi, riducendo nel contempo l’emissione di gas a effetto serra. Questa scoperta a detta degli studiosi potrà salvare vite non solo in Canada, ma in tutto il mondo.
