“…Bazı araştırmacılar, gözenekli volkanik cüruf agregalarının geoteknik özelliklerini belirlemeye odaklanmışlardır [21,22] Son yıllarda çeşitli volkanik cüruf agregaları veya katı atık maddelerin çimento ile stabilize edilerek geoteknik özellikleri iyileştirildikten sonra karayolları inşaat malzemeleri olarak kullanımı konusunda araştırmalar artmaktadır [23][24][25]. Çeşitli yüksek fırın cüruflarının, çimento, kireç, uçucu kül benzeri katkılarla stabilize edilerek yol temel/alt temel malzemesi olarak kullanımı ile ilgili çalışmalar literatürde rastlanmaktadır [25][26][27]. Doğal kaynakların azalması ve kırma taş ocağında üretilen malzemelerin eksikliğinden dolayı volkanik cürufların veya çeşitli cüruf atıkların yollarda dolgu malzemesi olarak kullanımı giderek daha popüler hale gelmektedir [28][29][30].…”

Kayseri Volkanik cürufu (VC), patlayıcı volkanik aktivite sonucu oluşan zemin ebatlarında ponza, kaya kırıntıları, puzolanik mineraller ve volkanik kül içeren doğal malzemelerdir. Volkanik cüruf, konik cüruf tepeleri şeklinde doğada hazır agrega olarak bulunmakta veya yapı temel kazılarından atık olarak çıkmaktadır. Bu çalışmanın amacı, Kayseri’de bol miktarda doğal olarak bulunan bu cürufların, havaalanı gibi geniş hacimli dolgu projelerinde ve esnek kaplamalı karayollarının temel, alttemel ve çeşitli dolgularında doğrudan veya çimento ile iyileştirildikten sonra inşaat malzemesi olarak kullanım potansiyelinin araştırılmasıdır. Elde edilen sonuçlar, volkanik cürufun yol dolgu ve alttemel tabakası için uygun olduğu ancak Kaliforniya taşıma oranı (CBR) değerinin düşük olmasından dolayı, zemin iyileştirme yapılmadan temel tabakası için uygun olmadığı ve kullanılamayacağını göstermiştir. VC'nin karayollarının temel tabakasında kullanımını araştırmak için, %3 ve %5 çimento ile stabilize edilerek tek eksenli basınç dayanımı (UCS) ve CBR deneyleri yapılmıştır. En iyi sonuç olarak, %5 çimento karışımıyla 7 ve 28 günlük UCS dayanımı sırasıyla 3,1 MPa ve 4,97 MPa ve CBR dayanımı sırasıyla %108,4 ve %148,6 elde edilmiştir. Bu değerler, temel tabakası için standartlarda belirtilen minimum dayanım gereksinimini karşılamıştır. Sonuç olarak, doğada hazır olarak bulunan volkanik cürufların %5 çimento ile stabilize edilmesiyle geoteknik özelliklerinin iyileştirilebileceği ve esnek kaplamalı yollarda temel, alttemel ve çeşitli dolgularda inşaat malzemesi olarak kullanılabileceği ortaya koyulmuştur.

“…However, the increasing amount of solid waste generated from the extraction and production processes is practically inevitable [1]. Additionally, parts of these solid residues are difficult to handle and occupy large areas of agricultural land, which causes a great impact on the environment [1,2]. This situation becomes even more complex when the terrestrial territory is limited and dispersed, as is the case of the Azores Archipelago (Portugal) [3].…”

“…This situation becomes even more complex when the terrestrial territory is limited and dispersed, as is the case of the Azores Archipelago (Portugal) [3]. Although it is responsible for an EEZ (exclusive economic zone) with about 954,496 km 2 , its total land area is only 2333 km 2 , distributed over 9 islands [4]. These islands are rather isolated, being far away from both Europe (1641 km) and North America (2985 km) continents [5].…”

“…Allied to these factors, polymers are equally versatile and durable, besides the fact that there is no damage in terms of their mechanical properties in the final products, compared to traditional materials [18,19]. On the other hand, and in line with the development of material science and engineering, these advantages can also be increased by combining polymers with mineral fillers, as in the case of sand extraction residues, resulting in composite materials [2].…”

“…In recent years, An [18] studied the performance of coal gangue pavement in airport construction, and Yang et al [19] used a theoretical analysis to promote the application of coal gangue in subgrade engineering. However, little research has reported on the practical application of coal gangue in roadbed construction, unlike waste slag [20]. Considering the difficulties in roadbed construction, the main challenge is to find methods that satisfy the use of coal gangue in practical settings.…”

As a massive solid waste, the high value-added utilization of coal gangue has received more and more attention in China. This study focuses on the utilization of coal gangue aggregate in railway engineering for coal transportation passage. Coal gangue aggregate was employed as high-grade railway subgrade filler andprepared concrete for roadbed drainage (named coal gangue roadbed protecting concrete—CGRPC). First, the basic properties of coal gangue such as particle size distribution, ignition loss, strength change under water softening, and compression performance were measured. Then, the technology to use coal gangue as filler in railway subgrade was put forward based on a real engineering application with the Jingang coal-carrying railway special line. Field tests showed that the coal gangue roadbed had excellent performance. The dynamic stiffness expressed as K30 was more 130 MPa/m, which meets the requirement for high-speed railway roadbeds. The distribution of vertical earth pressure according to the backfill depth showed a linear growing tendency. Finally, the technical and economic benefits of using coal gangue railway roadbeds were analyzed. The application of coal gangue near the railway line not only solved the problem of aggregate shortage in engineering construction, but it also consumes the coal gangue waste and leads to huge social benefits.
