INFLUENCE OF ALUMINA ADDITION ON THE MECHANICAL PROPERTIES OF WINDOW GLASSES FOAMED WITH SODIUM SILICATE
Abstract
In this study, the effect
of alumina addition (1-40 wt. %) on the mechanical properties of window glass
with 30 wt. % sodium silicate was investigated. Semi-wet mixtures were prepared
and shaped and heated in the oven chamber at 800°C for 30 minutes. The
microstructures of the glass foam material, densities, phase structures and
mechanical strength were determined. Glass foam has a closed pore structure
reduced by the amount of alumina addition (pore sizes: 0.5-1 mm) and the mechanical strength was
increased up to 10.2 MPa. The foaming rate of the
material is almost stayed stable up to 20% alumina incorporation. When the alumina
content is 20% by weight, the mechanical strength of the sample is 7.1 MPa,
the product has the density of 0.53 g/cm3, water absorption rate is
about 1.4%. The high mechanical strength and adequate porosity (79.45%) of this
product makes the material as potential to use in the building sector.

Abstract
Bu çalışmada, sodyum silikat (ağırlıkça %30
oranında) kullanılarak köpükleştirilen pencere camlarına ağırlıkça %1-40
oranında alümina ilavesinin mikroyapıya etkisi araştırılmıştır. Yarı yaş
şekillendirilen karışımlar 800°C de 30 dakika süre ile kamara fırında
sinterlenmiştir. Cam köpük malzemelerin mikroyapıları, yoğunlukları, faz
yapıları ve mekanik özellikleri belirlenmiştir. Cam
köpükler kapalı gözenek yapısına sahip olup gözenek boyutları alümina katkı miktarına
bağlı olarak düşmekte (0.5-1 mm) ve malzemenin mekanik mukavemeti 10.2 MPa
değerine kadar artmaktadır. Malzemedeki köpükleşme oranı %20 alümina katkı
miktarına kadar büyük oranda aynı kalmaktadır. Alümina katkısı ağırlıkça %20
olan numunelerde mekanik dayanım 7.1 MPa, ürünün yoğunluğu 0.53 gr/cm3,
su emme oranı %1.4 değerindedir. Yüksek mekanik dayanımı ve yeterli
gözenekliliği ile (% 79.45) bu ürün yapı sektörü için potansiyeldir.
