Klor İyonize Çimento Esaslı Kompozitlerin Doğrudan Analizi ve 2,5GHz Antenler ile Sensör Uygulaması

Öz

Bu makalede, mikrodalga yama antenleri kullanarak deniz kumu içeren çimento esaslı kompoziti ayırt eden bir sistem önerilmektedir. Deniz kumu kullanılan kompozit betonlar çelik takviyeli yapılarda kullanıldığında hayati tehlike oluşturabilecek hasarlara neden olabileceğinden inşaat mühendisliği sektöründe büyük bir öneme sahiptir. Öncelikle deniz kumu içeren çimento esaslı kompoziti analiz etmek için %0, %25, %50, %75 ve %100 klor iyonize deniz kumu içeren beton numuneleri üretilmiş ve kompleks dielektrik ölçümleri yapılmıştır. Ayrıca mikrodalga simülatöründe 2 adet 2.45GHz yama anteni tasarlanmış ve beton modellere entegre edilmiştir. Ayrıca, simüle edilmiş sonuçlar, bu yaklaşımın yaklaşık 30MHz rezonans kaymalarına sahip bir sensör olarak kullanılabileceğini göstermektedir. Son olarak önerilen sistem deneysel araştırmalarla desteklenmiştir. Bu tip konfigürasyon, kolay tasarım, kolay imalat, ucuz ve esnekten tahribatsız çimento bazlı kompozit beton ölçümlerine kadar birçok avantaja sahiptir.

Direct Analysis of Chlorine Ionized Cement-Based Composites and Its Sensor Application By 2,5GHz Antennas

Abstract

In this paper, we propose a system that discriminate cement-based composite including sea sand by using microwave patch antennas. The composites with sea sand have vital importance in construction engineering industry because ionised steel reinforced composites could cause life threatening damages. Firstly, to analyse cement-based composite including sea sand, 0%, 25%, 50%, 75% and 100% chlorine ionised sea sand containing concrete samples were produced and complex dielectric measurements were conducted. In addition, two 2.45GHz patch antennas were designed in microwave simulator and also it was integrated to the concrete models. Furthermore, simulated results shows that this approach could be used as a sensor with nearly 30MHz resonance shifts. Finally, proposed system was supported by experimental investigation. This type of configuration has many advantages as easy design, easy fabrication, cheap and flexible to non-destructive cement based composite measurements.
