Demiryolu Hızlı Onarımında Kaya Dolgu Beton Kullanımına Agresif Ortamların Etkisi

Year 2019, Issue: 10, 54 - 62, 31.07.2019

Abstract

Raylı sistemlerde hizmet
sürekliliği esastır. Çeşitli nedenlerle raylı sistemlerde meydana gelebilecek
aksaklıkların veya arızaların en hızlı bir biçimde giderilmesi gerekir. Aksi
takdirde, verilen taahhütlerin yerine getirilememesi sonucu maddi veya manevi
kayıplar söz konusu olacaktır. Bu nedenle, demiryolu demiryolu hat yatağında meydana
gelebilecek her türlü çökme veya toprak kayması gibi demiryolu trafiğini
aksatabilecek olayların neden olduğu problemlerin kısa sürede çözümü gerekir.
Bu çalışmada, demiryolu hatlarında meydana gelebilecek her türlü çökme veya
toprak kayması gibi zeminde boşluk meydana getiren olayların neden olduğu
bozulmaların hızlı ve güvenilir şekilde onarımı için ideal bir alternatif olan
kaya dolgu betonların kullanımına agresif ortamların etkisi araştırılmıştır. Bu
amaçla, üretilen standart silindir ve küp kaya dolgu beton numuneleri
donma-çözülme çevrimleri ve sülfat etkisi olmak üzere iki farklı agresif ortama
maruz bırakılmıştır. Agresif ortamlara maruz bırakılan betonlarda meydana gelen
birim ağırlık, ultrases geçiş hızı, yarmada çekme dayanımı ile basınç dayanımı
değişimleri irdelenmiştir. Ayrıca, kaya dolgu betonlar %0, 1 ve 3 oranlarında
süper akışkanlaştırıcı içerecek şekilde üretilerek akışkanlaştırıcı içeriğinin
kaya dolgu beton özelliklerine etkileri araştırılmıştır.

The Effect of Aggressive Environments on the Use of Rock-Filled Concrete in Railway Quick-Repair

Year 2019, Issue: 10, 54 - 62, 31.07.2019

Abstract

Service availability is very important in rail systems. It is necessary to eliminate any problems or faults that may occur in rail systems as quickly as possible. Otherwise, pecuniary loss and intangible damages will be incurred due to failure to fulfil the commitments given. For this reason, the problems caused by all the kinds of collapses or landslides that may occur in the base, subbase of the railway and natural ground need to be solved in a short time. In this study, the effect of aggressive environments on the use of rock-filled concretes, which are an ideal alternative for the rapid and reliable repair of disasters that can create a gap in the ground such as all kinds of collapses or landslides on railway lines, have been investigated. For this purpose, standard cylinder and cube rock-filled concrete specimens are subjected to freeze-thaw cycles and sulfate effect. After exposure to these effects, changes in the unit weight, ultrasound pulse velocity, the splitting tensile strength and compressive strength of rock-filled concretes are investigated. In addition, rock-filled concretes were produced with 0, 1 and 3% superplasticizer and effect of superplasticizer content on the properties of rock-filled concrete is investigated.
