在砂漿中的應用

Application in Mortar

膨脹珍

珠岩

Expanded perlite

珍珠岩

Perlite

1. 容重輕

（60～80kg/m³）

2．吸水率極大

3．顆粒強度低

4．導熱係數小

1. Low density

2.High water absorption

3.Low particle strength

4.Low heat conductivity

1．不規則與毛絮狀的外形，容易在砂漿攪拌過程中產生阻力，和易性極差。

1. irregular and floccus, easy to make resistance while mixing, bad workability

2．容重輕，顆粒強度低，本身有較好的熱工性能，但在砂漿攪拌過程中容易破碎，會很大程度降低其熱工性能

2. Low density, low particle strength, good thermal property itself, but break easily while mixing, and reduce thermal property.

3．吸水率大，使得砂漿的需水量增加，破坏了砂漿的凝固週期，使得砂漿的力學性能大大降低，極易產生空鼓、開裂，嚴重影響整個保溫系統的熱工性能和耐久性。

3. High water absorption, which increase mortar water demand, degrade its mechanical property significantly, then easy to have hollowing and craze, has a strong impact on the thermal property and durability.

閉孔珍珠岩

Hole-close perlite

珍珠岩

Perlite

1. 容重大

（120～180kg/m³）

2．吸水率較大

3．顆粒強度較大

4．導熱係數大

1. High density

（120～180kg/m³）

2. High water absorption

3.High particle strength

4.High heat conductivity

1．不規則的外形，在砂漿中易產生阻力，和易性差，攪拌時間長，造成其在砂漿中不易分布均勻，容易造成應力集中，引起空鼓、開裂，大大降低了砂漿的力學性能和熱工性能，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，導熱係數較差，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岩同樣的問題，不過在各項指標上要優于膨脹珍珠岩。

3. High water absorption, will have similar problems as expanded perlite while using, but have better performance than expanded perlite.

膨脹玻化微珠

Expanded and vitrified small ball

松脂岩

Perlite

1. 容重輕（80～120kg/m³）

2．吸水率小

3．顆粒強度較大

4．導熱係數小

1. Low density

（80～120kg/m³）

2.Low water absorption

3.High particle strength

4.Low heat conductivity

1．球狀顆粒，表面玻化，在砂漿攪拌工程中流動性好，和易性佳，能在短時間內攪拌均勻，降低了砂漿在干濕攪拌過程中的骨料破碎，有穩定的熱工性能與力學性能。

1. Spherical particle, surface vitrified, good fluidity while mixing, good workability, mixed evenly shortly, then reduce the aggregate broke when dry-wet mixing, good thermal property and mechanical property.

2．容量輕，導熱係數低

2. low density, light weight, low heat conductivity

3．吸水率小，很容易在砂漿中得到控制，收縮率小，不空鼓開裂，有穩定的熱工性能與力學性能，並且也相對提高了砂漿的使用壽命。

3. Low water absorption, easily controlled in mortar, low shrinkage, no hollowing and cracking, stable thermal property and mechanical property, increase the mortar service life.
