Over the last twenty five years or so we have been conducting trials and long term studies on Integral Admixtures and have shown that the life-span of cement bonded fibre, aggregate and other composites can be at least doubled.

Our experiments used commercially available water repellent additives that reduced the rate of wetting of the composite to reduce the damage done to the cementing matrixes by the weathering processes.

To reduce the release of fibers and the like research was conducted that prevented the destruction of the cementing matrix and in the process reduced the rate of degradation of the cement bonded composite.

The results of the 25 year study were published at the 2006 Inorganic Bonded Fibre Conference.

All cement bonded composites release the contents of the finished product into the environment and the case of fibers such as asbestos the released contents can have an adverse effect on the health of people who come into contact with such materials.
