浅谈泡沫混凝土保强度要求和温隔热原理

泡沫混凝土的强度在地板采暖过程中起着重要作用。除了良好的保温隔热性能,泡沫混凝土应具有抗压强度和抗压强度超过7MPa。注:普通混凝土2500kg每立方米,允许1% ~瓦斯含量高达5%,~ 80mpa抗压强度25MPa。

40% ~ 80%空气进入泡沫混凝土,每立方米200 ~ 1200kg泡沫,人数高达十亿,一堆鸡蛋,将大大降低弯曲强度、抗压强度低于0.4MPa时。在轴承、压力、抗震、弯曲和粘接等物理性能非常弱的情况下,却具有优异的绝缘、绝缘、隔音性能。

浅谈泡沫混凝土保强度要求和温隔热原理

实验结果表明,在不流动时,密封气体的导热系数很低。泡沫混凝土的孔质量存在50% ~ 80%为高,在孔圆孔相互封闭,避免空气交换对流,在泡沫转移层温度大大降低保温、隔热、隔音效果,泡沫保温性能和密闭定量决策。因此,用于地面加热泡沫混凝土的泡沫泡沫必须封闭,密封率越高,保温隔热性能越好。


The strength of foam concrete plays an important role in the floor heating process. In addition to good insulation and thermal insulation properties, foam concrete should have compressive strength and compressive strength of more than 7MPa. Note: ordinary concrete 2500kg per cubic meter, allowing gas content of 1%~5%, compressive strength of up to 25MPa~80MPa.


40%~80% air into foam concrete, foam per cubic meter 200~1200kg, number up to one billion, a pile of chicken egg, will greatly reduce the flexural strength, the compressive strength is lower than 0.4MPa. In the bearing, pressure, seismic, bending and adhesion of the physical properties of the very weak, but has excellent insulation, insulation, sound insulation performance.


The experimental results show that the thermal conductivity of sealed gas is very low when it is not flowing. The quality of the foam concrete pores exist as high as 50%~80%, is a circular hole in the hole closed to each other, to avoid convection of air exchange, temperature in the foam transfer layer is greatly reduced to thermal insulation, insulation, sound insulation effect, foam insulation performance and closed quantitative decision. Therefore, foam foam used for floor heating foam concrete must be closed, the higher the sealing rate, the better insulation and thermal insulation performance.
