Polypropylene fibres for the prevention of concrete cracks


These super-fine fibres offer the most effective means of preventing creation of cracks caused by concrete shrinking.

It is well known that concrete tends to crack during the first stage of setting as at this point concrete resistance is at its lowest point while shrinkage is at its highest.

Polypropylene fibres are the most effective fibres in prevention of crack creation as they are widely dispersed in the concrete and are extremely fine. So they offer higher fibre density compressing the cracks upon creation.
