Abstract

In this study, groutability of the microfine cement grouts (Rheocem 900) into sands having different particle sizedistributions is investigated by means of laboratory experiments. Groutability varies with rheological propertiesof suspension, grouting pressure, grain size distribution of soil, relative density, and fine content of soil. Fine,medium and coarse sands with different fine sand percentages of 10, 15, 20, 25, 30 are grouted with Rheocem900 suspensions having water/cement (w/c) ratios of 0.8, 1.0, 1.2. The success of groutability ratios in theliterature was investigated according to test results. As a result it was seen that fine sand percentage and w/c ratioare important factors that control the groutability.

Özet

Bu çalışmada, çok ince taneli çimento (Rheocem 900) süspansiyonu ile farklı gradasyonlara sahip kumlarınenjekte edilebilirliği laboratuvar deneyleriyle araştırılmıştır. Enjekte edilebilirlik süspansiyonun reolojiközellikleri, enjeksiyon basıncı, zeminin tane çapı dağılımı, zeminin relatif sıkılığı ve ince tane miktarı ile değişir.İnce, orta ve iri kumlardan oluşan ve ince kum yüzdesi (İKY) 10, 15, 20, 25 ve 30 olan numunelere, su/çimento(s/ç) oranı 0.8, 1.0, 1.2 olan süspansiyonların enjeksiyon deneyleri yapılmıştır. Deney sonuçlarına göreliteratürdeki enjekte edilebilirlik ilişkilerinin başarısı araştırılmıştır. Sonuç olarak ince kum yüzdesinin ve s/çoranının enjekte edilebilirliği kontrol eden önemli etkenlerden olduğu görülmüştür.
