Cenospheres colour selection
Cenospheres are alumina silicate hollow ceramic particles and are also referred to as microspheres, hollow spheres, microballoons or hollow ceramic microspheres.
Cenospheres are sought after as an inexpensive lightweight filler for use in cementitious and polymer systems.
Their spherical shape give low binder or water demand and increases fluidity to the mix.
Their composition and low density gives good flame resistance and excellent insulation properties.
