Abstract: | Buildings are consumers of large amounts of energy in all countries. In regions
with tough climate conditions, a good percentage of the total energy consumption is
due to cooling and heating of the buildings. The most important factor of saving
energy in buildings is to be aware of thermal properties of the construction materials.
The correct and effective use of thermal insulation in buildings contribute towards
reducing the required air-conditioning or central heating system size with further
reduction in the annual cost of energy. In addition, it could help in achieving thermal
comfort without reliance on electrical or mechanical air-conditioning, in particular,
during inter-season times. The amount of energy savings as a result of using thermal
insulation differ according to the building type, the location of building (climatic
conditions), and type of the insulation material used.
The objective of this research is to investigate the lightweight calcium-magnesium
based panel (LCMP) as a thermal insulation in buildings and also comparing the
costs of some ordinary insulation materials such as: polystyrene, polyurethane,
mineral wool and etc.
Thermal resistance (R), thermal conductivity ( ), thermal conductance (1/R) and
thermal transmittance (U factor) are main thermal factors of LCMP as a thermal
insulation material that measured separately. Also these factors measured for a wall
containing combination of LCMP and masonry materials. Experiments on fire
resistance, compressive strength, water absorption and pulse velocity of LCMP were
carried out.
Results show that the main thermal factors of LCMP are acceptable as per the
standards and building codes. Reaction of LCMP in case of fire indicates that it is
fire resistant. Water absorption of LCMP is slightly high. LCMP is also a fragile
material which is not strong enough to be used as a structural material. However, it is
suitable to be used as a thermal insulation for buildings. Pulse velocity test shows
that LCMP samples have a good uniformity.
The cost of manufacturing LCMP is 128 $/ m
3. When compared to other thermal
insulation material prices, the price of LCMP is reasonable.

Bütün ülkelerdeli binalar büyük miktarlarda enerji tüketcileridirler. Sert
ikilim sartlari olan bölgelerde, toplam enerji tüketiminin yüksek bir yüzdeligi,
binaların sogutma ve ısıtmalarından kaylanmaktadır. Binaların enerji tasarufundaki
en önemli faktör yapımateryallerinin termal özelliklerinin farkındalıgıdır.
Binaların ısıtma sistemin boyutunun azalmasına katkıda bulunur, ilaveten, yıllık
enerji maliyetinin daha da azalmasını saglar.
Buna ek olarak, elektrik veya mekanik klimaya itimat etmeden termal rahatlıga
ulasımasında yardımcı olur, billahassa ara-sezon dönemlerinde.
Tasarruf edilen enerji miktarı, termal izolasyon kullanım sonucu, bina tipine, binanın
konumuna (iklim sartlari) ve kullanılan isolasyon materyal çesitine göre farklılık
gösterir.
Bu arastırmanın amacı, binalardaki termal isolasyonlarda kullanılan hafif
Kalsyum-Magnezyum Tabanlı paneli (LCMP) arastırmak ve ayrica bazı sıradan
izolasyon materyallerini, örnegin: poistiren, poliüreten, amayant v.s. ile maliyetlerini
kıyaslamaktır.
Termal izolasyon materyali olarak, LCMP’nin ana termal faktörleri, ısı direnci
(R), ısı ilekenligi ( ), termal iletkenlik (1/R) ve ısıl geçirkenlikdir (U faktör) ki
bunalar ayrı ölçülürler. Hemde bütün bu faktörler, LCMP’nin duvar içeen
kombinasyon ve duvareılık materyallernde ölçülür. LCMP’nin yangın dayanımı,
basinç dayanımı, su emme ve nabız hızı deneyleri uygulanmıstır.
Sonuçlar gösterirki LCMP’nin ana termal faktörleri standartlarına göre ve bina
kodlarına göre kabul edilebilirdirler. LCMP yangın durumunda yangına dayanıklılık
gösterir. LCMP’nin su emmesi hafifçe yüksektir. LCMP’i kırılgan bir materyaldir ki
yapısal materyal olarak kullanım için yeteri kadar güçlü degildir. Ancak binalarda
termal izolasyon malzemesi olarak kullanılmak için yugundur. Nabiz hızı testi
LCMP örneklerinin iyi bir tekdüzelige sahip oldugunu gösterir.
LCMP’nin üretim maliyeti 128$/m3 . Diger termal izolasyon materyal
fiyatlariyala kıyaslandıgı zaman LCMP’nin fiyat makuldur. |
