学性能和热工性能，也影响到保温层的使用寿命。
1. irregular shape makes it easy to produce resistance, low workability, long mixing time, makes it unevenly distributed in the mortar, which will easy cause stress concentration, hollowing and cracking, reduce mechanical property and thermal property greatly, also has impact on the insulation layer service life.
2．容量大，导热系数较差，在砂浆中必须增加轻骨料掺加比列方能满足热工性能标准要求，轻骨料掺加量的增加必然会降低砂浆的力学性能或增加胶凝材料成本。
2. High capacity with bad heat conductivity, need to increase light aggregate to meet the thermal property requirement, but adding light aggregate will reduce mortar mechanical property and increase gelled materials cost.
3．吸水率较大，在应用过程中会出现上述膨胀珍珠岩同样的问题，不过在各项指标上要优于膨胀珍珠岩。
3. High water absorption, will have similar problems as expanded perlite while using, but have better performance t
