摘要：为降低泡沫混凝土生产过程中的能耗，改善泡沫混凝土的性能，研究了流变性对高早强免蒸压泡沫混凝土发气效果和硬化后性能的影响。结果表明：当屈服应力超过200 Pa后，泡沫混凝土不再膨胀；高早强免蒸压泡沫混凝土的6 h抗压强度可以达到2.7 MPa，导热系数基本不大于0.20 W/（m·K）；浆体的屈服应力偏小可能导致孔隙率（体积密度）相近的泡沫混凝土导热系数相差30%，抗压强度相差100%左右。 Abstract: In order to reduce the production energy consumption and improve the performance of foamed concrete, the effect of rheological properties on gas generation and hardening properties of high early strength non-autoclaved foamed concrete was studied. The results show that the foamed concrete no longer expands when the yield stress exceeds 200 Pa. The 6 h compressive strength of high early strength non-autoclaved foamed concrete can reach 2.7 MPa, while the thermal conductivity is no more than 0.20 W/(m·K). The lower yield stress can lead to a 30% difference in thermal conductivity and a 100% difference in compressive strength for foamed concretes with similar porosity (or volume density).

Abstract: In order to reduce the production energy consumption and improve the performance of foamed concrete, the effect of rheological properties on gas generation and hardening properties of high early strength non-autoclaved foamed concrete was studied. The results show that the foamed concrete no longer expands when the yield stress exceeds 200 Pa. The 6 h compressive strength of high early strength non-autoclaved foamed concrete can reach 2.7 MPa, while the thermal conductivity is no more than 0.20 W/(m·K). The lower yield stress can lead to a 30% difference in thermal conductivity and a 100% difference in compressive strength for foamed concretes with similar porosity (or volume density).
