Bendable concrete doesn't sound like the most secure product in the world, but scientists in Singapore are changing that concept.
The researchers invented ConFlexPave, which is a bendable, stronger, longer-lasting, more sustainable version of concrete. The development can create slim precast pavement slabs for quick installation and less maintenance.
Typical concrete comprises cement, water, gravel and sand. While this mixture makes concrete hard and strong, it does not promote flexibility. Thus concrete is brittle and prone to cracks if too much weight is applied.
ConFlexPave is specifically engineered to have certain types of hard materials mixed with polymer microfibres. The inclusion of these special synthetic fibres, besides allowing the concrete to flex and bend under tension, also enhances skid resistance.
