摘要
在常温常压条件下,研制了一种以碱性激发剂激发矿渣、生土为基材,以吸附储能相变石蜡的膨胀珍珠岩作为轻质骨料的低碳储能复合建筑材料(LPM),其28d抗折强度和抗压强度分别可达4.95MPa、23.05MPa。测试了材料的温度随环境温度及时间变化关系以及导热性能、力学性能,同时与硅酸盐水泥(OPC)进行了对比。结果表明:在外界温度发生变化时,此种复合建筑材料较硅酸盐水泥具有导热系数低,升温、降温速度慢,温度变化平缓、波动小的优点,且具有较好的力学性能。
Under the normal temperature and pressure condition,a kind of low carbon emission and power storage composite building material（LPM） is prepared,which is using alkaline activated agent acting slag and clay as the substrate,and using expand perlite with adsorption and power storage phase change paraffin as light aggregate.The corresponding flexural and compressive strength can reach 4.95MPa and 23.05MPa.The variation of temperature with environment temperature and time,thermal conductivity and mechanism properties are tested,meanwhile,the LPM is contrasted to the ordinary Portland cement（OPC） as reference one.The results indicate that when the environment temperature changes,compared with the ones of OPC,the thermal conductivity of LPM is lower,the temperature rising and cooling of LPM changes more slowly and the temperature fluctuation is less.Furthermore,the mechanism properties of LPM are better than the ones of OPC.
