partial replacement using admixtures • 3. Using fly ash as filler instead of sand
7
Parameters investigated and mix compositions
• The experiment purpose: • 1.The properties like density • 2.flow behavior • 3.water absorption • 4.strength of foam concrete
• 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.
8
Effect of water–solids ratio on design density
9
Effect of water–solids ratio on design density
10
Conclusion
• The consistency of pre-formed foam concrete mixtures mainly depends on the filler type.
5
The foam concrete
• Processing way: adding foam
•
aerating a foam agent
6
The foam concrete
The research status:
• 1. Cement-sand mixes • 2. Neat cement paste with or without
11
• Neat cement paste? Replaced cement paste? Admixtures?
