Abstract

Calcareous sand usually composed of particles of carbonite origin of relatively weak structure, high void ratio and low grain strength. These sands show different strength and dilation behaviour than quartzite sands due to the existence of calcareous material. Several locations on the Libyan coasts are containing calcareous sands or sands with considerable amount of calcareous material such as broken shells or shell fragments. The present study is concerning in investigating the effect of the amount and the size of the calcareous material on the shear strength behaviour of sand shell mixtures. Samples were obtained from a coastal site near the city of Benghazi. The sand shell mixtures were prepared at practically similar unit weight and at a dense state. Two series of tests were performed in direct shear box of 100x100 mm on reconstituted samples of dry sand, the first was mixed with proportions of 20,40 and 60 % of broken shells by weight of material, and the second was mixed with only 20% of shell sizes ranging from 0.85 mm to 4.75 mm. The results indicated generally increasing of the peak angle of shearing resistance (фp) and reduction of dilation response of sand with increasing the amount and size of shell material. Furthermore, larger compression with increasing content and size of shell material is also observed due to the crushing of shell material during shearing.

Sulandırılmış Kum Kabuk Karışımının Mukavemet ve Genleşme Davranışı

Abstract

Genellikle nispeten küçük yapılı, yüksek boşluk oranına ve düşük tane mukavemetine sahip karbonit kökenli parçacıklardan oluşan kalkerli kum. Bu kumlar, kalkerli malzemenin varlığı nedeniyle kuvarsit kumlarından farklı mukavemet ve genleşme davranışı göstermektedir. Libya kıyılarındaki çeşitli konumlar, kırık kabuklar veya kabuk parçaları gibi önemli miktarda kalkerli malzeme içeren kalkerli kumlar veya kumlar içermektedir. Bu çalışma, kalkerli malzeme miktarının ve boyutunun kum kabuk karışımlarının kesme mukavemeti davranışı üzerindeki etkisini araştırmakla ilgilidir. Bingazi kenti yakınlarındaki bir kıyı bölgesinden örnekler alındı. Kum kabuk karışımları, pratik olarak benzer birim ağırlıkta ve yoğun halde hazırlanmıştır. Yeniden yapılandırılmış kuru kum numuneleri üzerinde 100x100 mm'lik doğrudan kesme kutusunda iki seri test yapıldı, ilki malzeme ağırlığına göre %20,40 ve %60 oranında kırık kabuk ile karıştırıldı ve ikincisi sadece %20 ile karıştırıldı. 0,85 mm ile 4,75 mm arasında değişen kabuk boyutları. Sonuçlar, kabuk malzemesinin miktarı ve boyutunun artmasıyla genel olarak kesme direncinin tepe açısının (фp) arttığını ve kumun genleşme tepkisinin azaldığını göstermiştir. Ayrıca, kesme sırasında kabuk malzemesinin ezilmesi nedeniyle, artan kabuk malzemesi içeriği ve boyutu ile daha büyük sıkıştırma da gözlenir.
