學性能和熱工性能,也影響到保溫層的使用壽命。
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,導熱系數較差,在砂漿中必須增加輕骨料摻加比列方能滿足熱工性能標準要求,輕骨料摻加量的增加必然會降低砂漿的力學性能或增加膠凝材料成本。
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.吸水率較大,在應用過程中會出現上述膨脹珍珠巖同樣的問題,不過在各項指標上要優于膨脹珍珠巖。
3. High water absorption, will have similar problems as expanded perlite while using, but have better performance t
