Questions
Do you think how to reinforced the properties of foam concrete?
Neat cement paste? Replaced cement paste? Admixtures?
Topic
Influence of filler type on the properties of foam concrete
Content
Introduct the foam concrete
Parameters investigated and positions
Effect of water–solids ratio on design density
Conclusion
The foam concrete
Processing way: adding foam
aerating a foam agent
The foam concrete
The research status:
1. Cement-sand mixes
2. Neat cement paste with or without partial replacement using admixtures
3. Using fly ash as filler instead of sand
Parameters investigated and positions
The experiment purpose:
properties like density
behavior
absorption
of foam concrete
Effect of water–solids ratio on design density
Conclusion
The consistency of pre-formed foam concrete mixtures mainly depends on the filler type.
The flow behaviour mainly depends on the foam volume and as the foam volume increases the flow decreases.
For a given density, an increase in fly ash content of the mix results in increased strength.
