Günümüzde yapı inşasında en yaygın kullanılan yapı malzemelerinden biri olan beton; çimento, su, agrega ve katkı maddelerinin uygun oran optimizasyonu sağlanarak elde edilmektedir. Betonun fiziksel, kimyasal, mineralojik ve özellikle mekanik özelliklerinin istenilen düzeyde olması inşa edilen yapıların dayanımlı ve dayanıklı olması açısından önemlidir. Bu doğrultuda, beton karışımının önemli bir parçası olan agregaların seçimi beton özelliklerine etki eden önemli faktörlerden biridir. Agrega seçiminde sedimanter kökenli kayaçlardan olan kalker ve dolomitik yapıdaki kayaçların kullanılması agreganın çimento ile aderansının güçlü olmasını sağlamaktadır. Bu çalışmada Manisa-Gürle köyü yöresinde bulunan kayaçların tanımlanıp sınıflandırılarak beton içerisinde agrega olarak kullanımının uygunluğunun araştırılması amaçlanmıştır. Bu kapsamda, agrega numunelerinin fiziksel, kimyasal ve mineralojik özellikleri tespit edildikten sonra yıkanmış ve yıkanmamış agrega kullanarak 18 adet beton numunesi hazırlanmış ve 7, 14 ve 28 gün sonunda beton basınç dayanımları test edilmiştir. Çalışma sonucunda incelenen kayacın dolomitik kireçtaşı sınıfında yer aldığı, dolomitik kireçtaşı agregaların beton yapımında kullanılmasının uygun olduğu belirlenmiştir. Ayrıca yıkanmış agrega kullanımının yıkanmamış agrega kullanımına göre beton basınç dayanımını arttırdığı tespit edilmiştir.
Today, one of the most commonly used structural materials in construction, concrete cement, water, agrega and additives are obtained by providing adequate optimization. It is important that the physical, chemical, mineral and especially mechanical properties of the concrete are at the desired level for the construction of the structures to be sustainable and sustainable. In this regard, the selection of aggregates, which are an important part of the concrete mixture, is one of the important factors affecting the concrete properties. In the choice of Agrega, the use of calker and dolomithic structures, which are from sedimentary rocks, ensures that the aggregate's adhesion to the cement is strong. In this study, the purpose of the study is to identify and classify the rocks located in the area of Manisa-Gürle village and to investigate the suitability of their use as agrega in concrete. In this context, 18 concrete samples were prepared using washed and unwashed concrete samples after the physical, chemical and mineral properties of the agrega samples were identified and concrete pressure resistance tested at the end of 7, 14 and 28 days. The result of the study has been found that the cluster of the Dolomitic cluster of the studied ski is suitable for the use of Dolomitic cluster aggregates in concrete production. It is also found that the use of washed agrega increases the pressure resistance of concrete according to the use of unwashed agrega.
Concrete, one of the most widely used building materials in building construction today; cement, water, aggregate and additives are obtained by ensuring the appropriate ratio optimization. The physical, chemical, mineralogical and especially mechanical properties of concrete are at the desired level in terms of the strength and durability of the constructed structures. In this direction, the choice of aggregates, which are an important part of the concrete mix, is one of the important factors affecting the concrete properties. The use of limestone and dolomitic rocks, which are among the rocks of sedimentary origin, in the selection of aggregates ensures that the adherence of the aggregate with cement is strong. In this study, it was aimed to identify and classify the rocks in the Manisa-Gürle village region and to investigate the suitability of their use as aggregates in concrete. In this context, after determining the physical, chemical, and mineralogical properties of aggregate samples, 18 concrete samples were prepared using washed and unwashed aggregates and concrete compressive strength was tested at the end of 7, 14 and 28 days. As a result of the study, it was determined that the rock examined was included in the dolomitic limestone class and that it was appropriate to use dolomitic limestone aggregates in concrete construction. In addition, it has been determined that the use of washed aggregates increases the compressive strength of concrete compared to the use of unwashed aggregates.
