Influence of filler type on the properties of foam concreteLi JiaHarbin Engineering University2024/5/21 周二1QuestionsDo you think how to reinforced the properties of foam concrete？Neat cement paste?Replaced cement paste?Admixtures?2024/5/21 周二2Topic Influence of filler type on the properties of foam concrete2024/5/21 周二3ContentIntroduct the foam concrete Parameters investigated and mix compositions Effect of watersolids ratio on design density Conclusion 2024/5/21 周二4The foam concreteProcessing way:adding foam aerating a foam agent 2024/5/21 周二5The foam concreteThe 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 sand2024/5/21 周二6Parameters investigated and mix compositionsThe experiment purpose:1.The properties like density 2.flow behavior 3.water absorption 4.strength of foam concrete 2024/5/21 周二7 Effect of watersolids ratio on design density2024/5/21 周二8 Effect of watersolids ratio on design density2024/5/21 周二9Conclusion 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.2024/5/21 周二10That s all.That s all.Thank you for your listening.Thank you for your listening.Are there any questons?Are there any questons?2024/5/21 周二11
