Shotcrete: Shock-proof concrete

A team of researchers at the University of Nebraska-Lincoln has developed a unique type of conductive concrete that could prove a game changer. The brainchild of Professors Chris Tuan and Lim Nguyen, Shotcrete works by absorbing and reflecting either man-made or naturally occurring electromagnetic waves.

Standard concrete aggregates were thrown out during the research process. Replacing them was a secret ingredient: magnetite. This mineral has magnetic properties that soak up microwaves like a sponge. Carbon and metal components were also worked into the Shotcrete mix for further absorption and reflection enhancement.

Professors Nguyen and Tuan first investigated conductive concrete as potential de-icer for pavements, roads, airport tarmacs and the like. Its reflective properties also make Shotcrete ideal for guarding against electromagnetic pulses which could scramble any electronics held within a building. 

Shotcrete is available as a spray-on solution, so outfitting or renovating existing structures is claimed to be quick and easy.
