Cenospheres for Making Your Own Concrete Slurry
- Cenospheres are tiny hollow ceramic spheres. They are the by-product of coal burning power plants.
- Cement can bond to these spheres, so they are ideal for a slurry mix where normal sand is too large and grainy to fill small voids.
- Add to cement to create a slurry mix for filling pinholes and air pocket voids in concrete.
- Cement paste with cenospheres mixed in will greatly reduce the shrinkage of the slurry.
- Replace up to 20% of sand, by volume, with cenospheres to create stronger and lighter concrete.
- Cenospheres act as tiny ball bearings, making the cement slurry fill small voids much easier.
