Abstract
Bu çalışmada sülfürlü atık yerine ikame olarak %10, %30 ve %50 oranlarında inşaat atığı (İA) kullanılarak hazırlanan çimentolu macun dolgu (ÇMD) numunelerinin 3-28 gün boyunca tek eksenli basınç dayanımı (TEBD) ve 28 gün sonunda porozite (MIP) testleri yapılarak İA’nın macun dolgu malzemesi olarak kullanımı araştırılmıştır. Kontrol numuneleri %7,5 ve %8,5 bağlayıcı oranında hazırlanırken, İA ikameli ÇMD numuneleri %7,5 çimento oranında hazırlanmıştır. Bulgular, %10 İA ikameli ÇMD numunelerinin %7,5 ve %8,5 bağlayıcı oranında hazırlanan kontrol numunelerine kıyasla daha yüksek TEBD ve daha düşük porozite üretirken, daha yüksek oranlarda (%30-50) İA kullanımının dolgunun dayanım ve mikroyapı performansını olumsuz etkilediğini göstermiştir. Ayrıca, 1,0 m3 ÇMD üretiminde bağlayıcı oranı %7,5’e düşürülüp atık malzeme yerine %10 İA ikame edildiğinde %13,22 oranında bağlayıcı tasarrufu sağlanmıştır. Sonuç olarak, İA’nın yeraltı üretim boşluklarında ÇMD malzemesi olarak kullanılabileceği ve yerüstünde oluşabilecek toz, görüntü kirliliği ve depolama alanı yetersizliği vb. problemlerin ortadan kaldırılabileceği/azaltılabileceği öngörülmüştür.
In this study, cemented paste backfill (CPB) samples were prepared using the construction and demolition waste (CDW) at 10, 30 and 50 wt.% of replacement ratios to sulphide mine tailings. The unconfined compressive strength (UCS) and porosity (MIP) tests of these samples were practiced at 3-28 days and only 28 days, respectively and the utilization of CDW as paste backfill material were investigated. CPB samples of control were prepared at two different binder dosage (7.5 and 8.5 wt.%), whilst, the other samples substituting CDW were produced at cement dosage of 7.5 wt.%. Findings demonstrated that CPB samples having 10 wt.% CDW produced higher UCS and lower porosity than control samples produced at those binder dosage, whilst, the utilisation of higher replacement ratios of CDW (30-50% byweight) adversely affected the strenght and microstructure performances of paste backfill. When 10 wt.% CDW material to sulphide tailings was also replaced to produce 1.0 m3 CPB at 7.5 wt.% of binder dosage, the binder saving of 13.22% was obtained. As a conclusion, it was foreseen that the CDW can be utilized as CPB material in stopes of underground mine and the problems as dust, visual pollution and inadequancy of storage site etc. which may be occurred in surface can be elliminated or minimised.
