Application in Mortar

膨脹珍

珠巖

Expanded perlite

珍珠巖

Perlite

1. 容重輕

（60～80kg/m3）

2．吸水率極大

3．顆粒強(qiáng)度低

4．導(dǎo)熱系數(shù)小

1. Low density

2.High water absorption

3.Low particle strength

4.Low heat conductivity

1．不規(guī)則與毛絮狀的外形，容易在砂漿攪拌過(guò)程中產(chǎn)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(qiáng)度低，本身有較好的熱工性能，但在砂漿攪拌過(guò)程中容易破碎，會(huì)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，破壞了砂漿的凝固周期，使得砂漿的力學(xué)性能大大降低，極易產(chǎn)生空鼓、開(kāi)裂，嚴(yán)重影響整個(gè)保溫系統(tǒng)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.

閉孔珍珠巖

珍珠巖

Perlite

1. 容重大

2．吸水率較大

3．顆粒強(qiáng)度較大

4．導(dǎo)熱系數(shù)大

1. High density

（120～180kg/m3）

2. High water absorption

3.High particle strength

4.High heat conductivity

1．不規(guī)則的外形，在砂漿中易產(chǎn)生阻力，和易性差，攪拌時(shí)間長(zhǎng)，造成其在砂漿中不易分布均勻，容易造成應(yīng)力集中，引起空鼓、開(kāi)裂，大大降低了砂漿的力學(xué)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(dǎo)熱系數(shù)較差，在砂漿中必須增加輕骨料摻加比列方能滿(mǎn)足熱工性能標(biāo)準(zhǔn)要求，輕骨料摻加量的增加必然會(huì)降低砂漿的力學(xué)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(yīng)用過(guò)程中會(huì)出現(xiàn)上述膨脹珍珠巖同樣的問(wèn)題，不過(guò)在各項(xiàng)指標(biāo)上要優(yōu)于膨脹珍珠巖。

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

1．球狀顆粒，表面?；?，在砂漿攪拌工程中流動(dòng)性好，和易性佳，能在短時(shí)間內(nèi)攪拌均勻，降低了砂漿在干濕攪拌過(guò)程中的骨料破碎，有穩(wěn)定的熱工性能與力學(xué)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(dǎo)熱系數(shù)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(kāi)裂，有穩(wěn)定的熱工性能與力學(xué)性能，并且也相對(duì)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.
