While a normal concrete mixture is strong, it can be made to be much stronger by adding in some fibre to the mixture. Most of the time the fibre is glass and although pretty weak in itself, the fibre helps the concrete hold together better. Adding glass fibre to your concrete is a quick and affordable process that will leave you with much stronger results.

  1. 1

    Create a low slump concrete mixture that can stand on its own when placed inside a form. Mix the concrete inside a wheelbarrow with a spade according to the manufacturer's directions.

  2. 2

    Line your concrete form with a 1/8-inch layer of your low slump concrete to create the finish layer. This layer will hide the rough fibre-reinforced concrete.

  3. 3

    Mix up equal parts sand and cement as well as AR glass that weighs less than four per cent of the whole mixture to create your fibre filled cement. Add an acrylic emulsion that is equal to five per cent of the total mixture weight. Add additional water to the mixture until you get a thick mix that you can pour.

  4. 4

    Pour your newly made fibre filled concrete in to the form on top of the finish concrete you poured earlier.

  5. 5

    Spread a layer of the low slump concrete over the top of the fibre filled mixture.

Tips and warnings

  • Wear work clothes when handling concrete because it may splash up and ruin any good clothes.
