Abstract

Ülkemizde
bulunan Kangal Termik Santrali’nde çok miktarda uçucu kül birikmektedir. Bu
santralde üretilen uçucu küller depolama alanlarına dökülmekte, ciddi çevre
problemleri ve sağlık sorunlarına sebep olmaktadır. Atık cam da bazı problemler
doğurmaktadır. Geri dönüşümü olmayan camların çoğu, çevre dostu bir çözüm
olmayan depolama alanına gönderilir. Dolayısıyla, atık cam biyolojik olarak
ayrışmadığından, yapı sektöründe kullanılmasına kuvvetle ihtiyaç vardır.  Bu çalışmada, uçucu kül, kireç ve cam tozu
kullanılarak yapı blokları üretildi. Bloklar 70 ^oC sıcaklıkta 24,
48, 72 ve 96 sa.’lik sürelerde kür edildi. Blokların basınç ve yarmada çekme
dayanımları, su emme, kılcal su emme ve yoğunluk değerleri belirlendi. Kür
süresinin yanında, blok içerisindeki kireç ve atık cam tozu gibi ilave
malzemelerin miktarlarının da sonuçlar üzerinde direk etkili olduğu bulundu.
Elde edilen sonuçlar, bu atık malzemeler kullanılarak blok üretilebileceğini
gösterdi.

Production of block by using fly ash, lime and glass powder

Abstract

A
large amount of fly ash is accumulating in Kangal Thermal Power Plant in our
country. Fly ash produced in this plant is abandoned to the landfills and
causes certain serious environmental problems and health hazards. Waste glass
also constitutes some problems. The most of non-recyclable glass is sent to
landfill that is not an environment-friendly solution. Therefore, there is a
strong need to be utilized it in building sector because it is not
biodegradable. In this study, masonry blocks were produced by using fly ash, lime
and waste glass powder. Blocks were cured for periods of 24, 48, 72 and 96
hours at 70 °C. The compressive and flexural strengths, water absorption,
sorptivity and density values of blocks were determined. It was found that
curing time and amounts of additional materials that were lime and waste glass
powder in the block were directly effective on the results. The results
obtained showed that block could be produced by using these waste materials.
