                            <p>It is defined as the concrete made by spraying and consisting of aggregate, cement, water and some chemical additives transmitted with compressed air through the sprayed concrete pipeline, which is frequently used especially in the mining and construction industry. It is widely used in many areas such as underground engineering constructions, rock and ground support, coating and repair of structures, as it can be applied quickly without the need for reinforcement, can be shaped as desired and applied to any surface. In addition to these advantages, different amounts and structures of fiber can be easily added to the concrete. With the developing technology, the use of fiber in concrete has increased. The main reason for the use of fiber is its energy absorption feature. This property, which is also called toughness and expresses the area under the load-deflection curve, is related to the mechanical property (Crack resistance, ductility, impact resistance as.) of the material. Toughness energy absorption is generally measured by two different methods. These are the EFNARC plate bending test and the round plate bending test. In this study, plate bending tests used in sprayed concrete and other fiber concretes were investigated in detail and literature studies were examined.</p></trans-abstract>

Tahkimat gerektirmeden hızlı bir şekilde uygulanabildiği, istenilen şekilde şekillendirilebildiği ve her türlü yüzeye uygulanabildiği için yeraltı mühendisliği inşaatları, kaya ve zemin desteği, yapıların kaplama ve onarımı gibi birçok alanda yaygın olarak kullanılmaktadır. Bu avantajlarına ek olarak, beton içerisinde farklı miktar ve yapıda lif kolaylıkla katıla bilinir. Gelişen teknoloji ile betonda lif kullanımı artmıştır. Lif kullanımının temel nedeni enerji sönümleme özelliğidir. Tokluk olarak da isimlendirilen, yük-sehim eğrisinin altında kalan alanı ile ifade eden bu özellik, malzemenin mekanik (Çatlak direnci, süneklilik, darbe direnci vb.) özelliği ile bağlantılıdır. Tokluk enerji absorbsiyonu genel olarak iki farklı yöntemle ölçülmektedir. Bunlar EFNARC plaka eğilme deneyi ve yuvarlak plaka eğilme deneyleridir. Bu çalışmada püskürtme betonda ve diğer lifli betonlarda kullanılan plaka eğilme deneyleri ayrıntılı bir şekilde araştırılmış ve literatür çalışmaları incelenmiştir.</p></abstract>
