New concrete without cement can bend under load without breaking into pieces

New concrete without cement can bend under load without breaking into pieces

Researchers have introduced a new type of concrete that cracks but does not crumble when stretched or bent.

In the modern world, concrete is the most common building material and the second most consumed substance after water.Therefore, its properties and quality are very important for buildings, bridges, tunnels and other infrastructure facilities.

A team of scientists from Swinburne University of Technology has developed a new type of concrete, which includesindustrial waste, such as ash from coal-fired power plants, andsmall polymer fibers. Thanks to these inclusions, it does not collapse and does not break into pieces when cracks from deformation occur.

In fact, it can bend when a force is applied to it, so the structures built from it can remain intact after earthquakes, hurricanes, or even explosions and shells.

It  uses 36% less energy and emits 76% less carbon dioxide compared to conventional flexible cement concrete.

Recently, we also reported on the invention of an additive for concrete, which allows it to be poured at temperatures below zero without loss of quality.
